Hi Nate. You must have read my mind, as I was thinking of almost exactly the same thing! I was thinking of a setup for about 500 quid, but not sure where to start...

I';ll keep an eye on this thread, but also add any info that I stumble across if I think it will be useful.

How about this - https://www.think3dprint3d.com/3D-Printer-Kits/complete-3D-printer-kits/Kossel-Mini-3dPrinter-Kit (https://www.think3dprint3d.com/3D-Printer-Kits/complete-3D-printer-kits/Kossel-Mini-3dPrinter-Kit)

Build volume: cylindrical, 170mm diameter, 245mm height.

Footprint: triangle, 300 mm width.

Frame height: 650 mm.

but its not a Cartesian printer, its a Delta

I';ve just finished a Delta, which is essence is the same, but just scaled a little larger

The best starter printer I could recommend is a wanhao duplicator 4x, I started on one of these and I loved it, heated build platform, full enclosed and can pick them up between 300 and 500 quite easy. Delta printers are not something I would recommend for a beginner into 3D printing, I purely base that on issues I had and I had 12-18 month of printing experience.

Yes CTC printers are good, they take quite a bit of time to set up, but once done prints are good quality and reliable.

No worries buds, Cdc are box type printers(easy way to describe) and delta are like the mini Kossel, I have a similar printer to fletch about the same size too and mine is a Kossel xl

I did have have to mod my CTC, like installing a glass bed, enclosing panels, wire chain for the X axis cables and moving the filament high up.

Designs? Simple designs I rush up on TinkerCAD - an on-line site which is quite good, even if the designs need to be straightforward. I';m no CAD artist - mainly making up practical parts for various stuff.

like any software, its more of how you use it than how it appears.

I initially started designing using tinkercad with the mind to move onto more complex software.

it wasn';t till I did move onto said software that I realised its was surprisingly unnecessarily complex and I unerringly found myself returning to tinkercad repeatedly.

on first glance it looks incredibly simplistic and almost childish (afterall it uses the "building block" approach to design which means in many ways it is) but Ive found that depending on how you utilize its design features you can produce even the most complex designs and I often use it as a preferred tool during projects..... though its occassional server sloth fits can really p*ss you off.

Wow, there';s certainly a lot to learn about in the world of 3D printing.

Thanks so much for all the input so far guys.   :beer2:

It';s clearly far more diy/hands on than I realised, but that hasn';t put me off at all.

Did anyone bother reading up on the subject before buying a machine, and if so can you recommend a good and useful book?  I';m considering buying one of the following three books about it:

http://www.bookdepository.com/3D-Printing-James-Floyd-Kelly/9780789752352?redirected=true&utm_medium=Google&utm_campaign=Base6&utm_source=UK&utm_content=3D-Printing&selectCurrency=GBP&w=AFC7AU9SBR6UL7A8ZT7N&pdg=kwd-104399158419:cmp-177155787:adg-15139031667:crv-44091921627:pid-9780789752352&gclid=CJ6jpt_Ch88CFcG4Gwod_JsI7w (http://www.bookdepository.com/3D-Printing-James-Floyd-Kelly/9780789752352?redirected=true&utm_medium=Google&utm_campaign=Base6&utm_source=UK&utm_content=3D-Printing&selectCurrency=GBP&w=AFC7AU9SBR6UL7A8ZT7N&pdg=kwd-104399158419:cmp-177155787:adg-15139031667:crv-44091921627:pid-9780789752352&gclid=CJ6jpt_Ch88CFcG4Gwod_JsI7w)

https://www.amazon.co.uk/dp/1457182939/ref=wl_it_dp_o_pC_S_ttl?_encoding=UTF8&colid=1VZDWMT535IFD&coliid=I157P06V21IJCL (https://www.amazon.co.uk/dp/1457182939/ref=wl_it_dp_o_pC_S_ttl?_encoding=UTF8&colid=1VZDWMT535IFD&coliid=I157P06V21IJCL)


So it looks like there';s no one go-to brand or machine for the best budget 3D printer.  It';s cool that there';s so many different designs and units available but it means I';ll be taking a little longer than planned to make a decision about which one to go with.

For the uninitiated (like me) I';ve learned that there are 3 main types of 3D printer:

Delta - Generally tall tripod machines where the printer bed is fixed and the arms holding the print nozzle move up and down the vertical pillars in order to give the extruder the necessary movement.
Cartesian - Generally boxy printers (open and encased) where the flat bed moves up/down and forward/back whilst the print nozzle runs left/right across the top.  Printing certain shapes is more difficult due to the constant flat bed movement and the machines generally take up more desk space..
Polar - The daddy of 3D printers where the flat bed rotates whilst the print nozzle moves left/right and also up/down giving full 360 movement quickly and efficiently.  Machine';s can be small whilst printing big!

I like the looks of the Polar unit, but at $899 + import costs I think price will put me off of buying one!  Very cool though.   :cool:

Cheers DarkButterfly for all the excellent pics and info about your CTC machine.  That';s a nice looking bit of kit.  And I like your makeshift storage-box hood (hillbilly enclosure, as shawdreamer puts it lol)!

I was confused what was meant by the glass bed, but now I understand that it';s just a bespoke sheet of toughened glass laid onto the standard heated bed for better heat dispersion and print material adhesion.  Boro glass is meant to be very good apparently.

What are you using in the 3rd to last photo as flat bed adhesive?  I';ve read that masking tape, dried PVA glue and even prit-stick works well.

How did you fabricate the side panels?  Are they cut-to-fit sheets of standard acrylic?


Rommie, the Wanhao Duplicator 4s looks decent.  It gets plenty of love around the web.  Cheers for the heads up.  I think the newer one is the 4S.  I';ll take a proper look at that too.

When it comes to making enclosure, (or airframes) I';m not just frugal, I';m downright cheap and will not waste time making a box if I already have one to fit ~~

I had some acrylic sheets left over form another project, so I cut them to fit, but they are standard acrylic.
The adhesive I use on glass is super hold hairspray.

Hopefully this helps ~~

Hmmm, I think that upon reflection I was perhaps a bit unkind to TinkerCAD.  ::)

As you rightly say, it is surprisingly flexible and I have made a couple of complex designs myself also.  Its just a matter of getting your head around how to combine various shapes and holes to come up with the whole thing.   

But yeah, I';d agree with you wholeheartedly, its a rather fabulous tool.  More so that you can stop your work, shut down the browser, go off somewhere else and pick up again from where you left off.  I';ve even done some sneaky edits at work in a spare browser tab ~~ 

I have recommended TinkerCAD before to people who';ve never done design work.  The great feature is to be able to visualise your design in the 3D viewer where you can see how the design is going to come out.

Nate80

First thing you have ask yourself is do you want it to work out of the box,  Require minimal assembly, a printer in kit forum taking several hours of building or going totally custom and sourcing the parts required?

Answer that and we can point you in the direction of your choosing.

Are there restrictions depending on what type of unit get ? Some have moving tables, static tables, the Delta type seem totally different to the rest. Have they any advantages ?

I wouldn';t term it as "restriction" as such, to a certain degree each type excels at certain print types, for example kossel types are superior to Mendel types when it comes to building taller prints while maintaining quality whiles Mendel types are often better at building large footprint designs.

Its probably more about personal preference when choosing what printer is best for yourself, Mendel types are often the preferred printer for a newcomer as there easier to setup and get calibrated with limited experience which means you can often get printing quicker, kossels print better quality but require alot more experience, time, calibration and general effort to get them to do so consistently which means a much larger learning curve for a newcomer.

The reason you see so many variations on the Prusa and similar is due to their ease of setup and use.

I';m not completely sure yet, that';s what I';m here for - to work that out.   ;)   It';s a bit tricky as I';d guess (as with most things) if you want ease and productivity it';ll cost lots of conga, so a budget ready to use 3D printer will probably offer less features etc.

I';m great with building stuff and fine with performing basic electronics, and I';m good with computers, so I';m happy to buy bits and build it - as long as it';s guaranteed to work when it';s all put together and calibrated!   :laugh: 

I';m still trying to figure out what style of 3D printer is best for my needs.

kossels print better quality but require alot more experience, time, calibration and general effort to get them to do so consistently which means a much larger learning curve for a newcomer.

I';ve been reading that Kossels (Delta';s) are not so good for ABS printing and that the material is more likely to shrink and warp in a Delta?  I';m really interested in printing ABS so that wouldn';t be good, if it';s true?
Title: Re: WHICH? 3D Printer
Post by: JeremyE on September 13, 2016, 12:14:58
I have the Duplicator I3, and while it prints fantastically, the biggest issue I find is adhesion to the print bed because it needs to be calibrated more than a Delta. If I had to look again at getting a new printer, it would be a delta style every time. Easier calibration, faster printing, less desk space and easier to enclose.

I did not find the learning curve of 3D printing hard at all (I am and electronic engineer but still think anyone can grasp it).

the only reason abs and kossels seem less compatible is due to the shrinkage ABS undergoes during cooling, this is only really a problem when your building a tall design though (which Kossels are most suited for, hence why the bad press with ABS).

Without a good solid footing (bed adhesion) ABS can be a pain on any printer, regardless of type, its said that enclosing a Kossel helps it maintain a higher degree of ambient air temp which would certainly help with ABS shrinkage during printing.

Generally speaking though, if your using ABS then the main battle is with its first layer and bed adhesion, get that right and usually any printer can use ABS successfully.

I myself very rarely use any other filament type than ABS, Ive used Petg for some structural components and flexible PLA for a couple of phone covers for my lad but since moving from mainly PLA printing to ABS Ive not used PLA since.

All my quad designs are done in ABS and stand up to some very punishing treament.

+1 for ABS

I run my Duplicator 4 in a small study that has no draughts and is quite warm throughout the year.  ABS shrinkage has not been a problem for me in that respect.  Early days, in more open parts of the house I did have some problems with prints....

Bed adhesion of first layer is critical and i find that a disk-shaped test print helped me get the calibration of the print bed just right.  I print on to Kapton tape - glass just didn';t work for me - and the adhesion is brutal  ::)  Just remember to let the bed cool down before trying to remove the print.  I use a sharpened pallet knife to help, just keep fingers away from the blade  :o  When the ABS lets go it does so quickly  ~~

Post by: Hozza on September 13, 2016, 12:42:48
Kossel will print abs but the thermal shock is the biggest problem, either a warm room or encased machine will sort the issue, however I print with an open printer in a victorian property that I can';t double glaze, so in winter abs is a no go but I found PETG and it';s so much better than abs for strength and durability, a ****** to get settings correct for but once it';s dialed in you wouldn';t go back to abs.

So what I think I';ve concluded is that cartesian';s and delta';s are both good and the best - depending on who you talk to and which machine they run personally!  :laugh:   ;)

Seriously though, there';s so much differing opinion all over the net that I don';t think there';s a definitive answer just yet as to what is best for who.  I guess it';s too early days and the 3D printer market hasn';t grown big enough yet in order for the mainstream testers and journalists to highlight a selection of printers best suited for certain jobs and the various categories of purchaser: hobbyist, educational, commercial etc.

I generally read that Delta';s are harder to calibrate than cartesian';s and less aimed at newbs, but some think the opposite.  And ABS appears to be either the best print material ever, or the cause of many heads lacking hair anymore.  I';ve read conflicting reports that PETG is both fantastic and awful, that glass beds are both a necessity and a waste of time, that ready to run machines like the DaVinci models are both fantastic and utter c*@p etc.

 :help:  It';s no walk in the park, this 3D printer malarky!   :blink

I';m really enjoying learning about it all though.   ::)

I';m using my printer as I type this post, its printing a float switch adjustable mount in ABS, its a bed of two parts that are holding nicely to the glass bed under a fairly liberal layer of hairspray.

The thing with the conflicting information is that its dependent on the individual and what works for them, as you said above, its a case of experiment and find what works for you, it took me many attempts to get it working consistently.

On a side note I have more hair than when I started :laugh:

I';m pretty sure it';ll all come clear to me suddenly and I';ll know which machine';s right for me.  Usually works that way I find.   ~~

At the moment I like the look of the CTC unit, the original Wanhao Duplicator 4S and the PRUSA I3 mk2 3D (the official one seems to have some wicked upgrades like PEI print surface and auto levelling - but I haven';t checked out any of the clones yet, if they even exist yet).  I like the fact Delta';s take up less desk space but I';ve still got to learn a bit more about them before I decide if they';re for me or not, and if they are, which one.

I have been obsessed with getting shot of my Wanhao 4x recently looking for an excuse for a meaty (expensive upgrade)
I';ve taken the Wanhao as far as it will go, all metal hot ends, modified drive system for flex filament, stiffened arms, fan shroud etc. etc. etc.
The thing is I';ve just come to the realization that there is nothing viable that can print PLA, ABS, Carbon Fiber, Flexible, PETG as well as I currently have mine set up for.
The build platform is a tad small, but that';s the only downside. I haven';t actually dropped a part into my slicer that is too big anyway so it makes no sense to get rid.
I looked at the quality of a couple of prints I did today with no brim, raft, supports or any of that and I was still mighty impressed.

Oh, and take heed, I';m still banging the drum for laminator pouches as a bed surface. Forget all the ABS slurry, Kapton tape, Blue Tape, Glue Stick, Hairspray, Buildtak concoction of confusion. One surface works for all. Trust me.

So what I think I';ve concluded is that cartesian';s and delta';s are both good and the best - depending on who you talk to and which machine they run personally!  :laugh:   ;)

Wrong lol I run a totally custom built i3 I even had my own frame milled and cut, but the i3 has it';s issues the biggest being the moving print bed and a Kossel XL is the way forward :laugh: I know it';s a better design due to less inertia, it prints faster 3 to 4 times faster and has much better electronics.

Who supplies a good kossel kit ( or clone ) of parts ? There are quite a few and the only supplier I';ve found in the uk sells the mini. Do you have to keep these open framed units covered to stop dust ? One video I';ve seen the print head needed changing and the belts to the side restricted what size you print making the table size pointless.

I';m building a big delta6 at the moment, ooznest stock most of what you will need.
once you go large so does the price, if you can';t print plastic parts, -  some of the parts are 10hr prints so take some time to get there.

Once you';ve taken the plunge and have bought a machine I totally agree that';s generally the best way to go.   :smiley:  But before you';ve bought a machine I reckon it';s definitely best to ask owners with real-world-experience which machine';s perform best - and why.  Otherwise it';s a bit like buying a new car or motorbike without finding out what';s considered the best, and then soon after finding out you bought the wrong one and it doesn';t do what you wanted.   :banghead:

The Kossel from T3P3 is a well sorted kit that if built accurately will produce excellent prints.

The big advantage over any other kit AFAIK is that it comes with all Top notch Electronics to take advantage of the cutting edge in performance at this Time ie it has a 32 bit controller board (absolutely essential to get the most out of a delta) it also has a DC42 Mini IR sensor board which means that the Delta will auto-calibrate in under 60 seconds and once set up properly will do it in about 30 secs.

This so quick I have it run at the start of every print and this takes care of any fluctuations due to Temp differences (And yes Aluminium does expand by quite a large amount believe it or not.

I print almost exclusively ABS with the occasional Petg thrown into the mix with no issues and the printer is not enclosed is just in a draft free heated room.

Coming to the Robotdigg all metal Kossel it is excellent for all the mechanical parts in it but is let down IMHO by old 8 Bit ellectronics need to manually calibrate it and a poor extruder.

Both these kits have a very similar build size.

To increase the build size is a simple matter of replacing the Extrusions with longer ones and the Carbon arms also need to be lengthened both of which are relatively easy to do?

The one upgrade to the T3P3 that I think would be well worthwhile is a set of Robotdigg Aluminium corners. (T3P3 may even have some)

As I have said previously I started with a I3 and moved to a kossel of which I have now built 3 (Mine Rommies and part built Hozzas) and have another (very large one) on the way.

At the end of the day there is no best option except maybe for a Stratasys printer if you have very deep pockets?

And just to throw another design into the Mix there is CoreXY which will be my next design once the Mega Delta is finished and more funds become available.

Thank you, thats really interesting.   I may have missed it but what filament material are you using for this method?  Will it take the bed heat for ABS (110C) for example?  I';ve a ton of unused laminate so am interested try this out.
Title: Re: WHICH? 3D Printer
Post by: Sweet Pickle on September 15, 2016, 04:03:41
Works on every filament I';ve tried. All the ones mentioned in my initial post i.e. Flexible, PLA, ABS, Carbon Fiber and PETG.
It can take all temperature ranges.
I print Carbon, PLA and Flex 1t 50-60 and ABS and PETG at 100-110.
Quite durable, one sheet will last an age and if you heat the bed up to 40-50 it will peel off with no residue. Grips like a swine mind, taking it off cold can be done but it';s not easy.

After being burnt with Geetech in the past (Ripping off beta devices and then continueing to sell them even tho they have been shown to be dangerous (even the Designer changed the design due to this but never finished or released it due to Geetech)) I would never ever touch any product they release ever again.

Now to that Delta it is very old design using 8mm steel rods for the linear motion which just aren';t stiff enough for the job they use very poor rods ends for the Diagonal rods that do not give enough movement and also have a lot of backlash/slop in them (Not good for a delta). There extruders are weak the Hot end is a rip off of the Diamond Hotend and not done very well either they are using Rip off E3D Heatsinks and not cooling them Properly.

Don';t think I really have to say much more

+1 the above  ~~, Hear Hear.  Get stuck in and see what happens.  My Kolobus (nee Wanhao) Duplicator 4 is un-modded and produces a mean print, in ABS, using just Makerware to lay out the parts, slice and print all in one app.   I have treated it like an appliance rather than a project, although I am 100% certain you could do just the opposite.

In My view there are a few issues with this kit.

1. The heatbed being that large at 12V will draw an awfull lot of current prob close to 20 amps and a Cheap SSR (Which is what is prob supplied) will drop upto 2V itself (40W of heat to get rid of) and this will also slow down the Heating of it.
2. * bit electronics which are known to struggle with Delta Maths esp. when fitted with the Display?
3. Plastic printed parts which if not 100% perfect will affect the accuracy of the Build and hence make Calibration difficult.
4. and this may be an issue it all depends on which Wheels they are supplying most cheap Chinese/eastern europe kits tend to use Shower door wheels which are Bad (They wont go to the expense of good double bearinged vee wheels) but it is difficult to see in the pics.

At the end of the day you pays your money and takes your pick.

I would NOT be able to help with those electronics on a Delta as I have allways used a Duet 32 bit board which I now know almost backwards.

There is two ways to get into 3D printing, one being buying right from the start and creating a working printer be it pre-built or kit, the other is buying a printer than you know will be a pain to print with on a daily basis and mod it to work for you, so in saying that it depends on what you want and your life style as some love to tinker and other would just open the window and introduce it to the back garden.

The best part of building a Kossel XL will be you can buy it bit by bit instead of one huge out lay and have it sat in the corner gathering dust like mine.

Can point you in the right direction for the parts mate only need to go to 3 or 4 suppliers for all the bits,

and not many from China either (Just the Alluminium corners and carriages from Robotdigg)

give me an idea of the size you would like to go to and I can give better info (Fletches BOM is pretty damned good for sources as well).

both mine and Fletches are 1 mtr tall with 500mm side extrusions and this will give around 360mm dia x 450-500 hight

Yep I knew that and that is one of the choices any new builder needs to make.

Those corners weren';t available when I did the 3 that I have done so far however the next one is having 40x40 verticals and 20x80 horizontals bar one face where there will be a 20x20 and a 20x40.

Chris it';s like anything you will basically get what you pay for, but with your background and knowledge I';m sure you could turn it into a a capable printer with a little outlay, what normally happens is they are brought by people who are led to believe 3d printing is plug and play, which is something it isn';t especially at that price range.

When looking at Prusa i3 clone';s I was initially interested in the geeetech i3, but in the end I decided against it after reading so many negative reviews and opinions from owners. The negative comments about all of geeetech';s printers was pretty overwhelming tbh. They included poor construction, bad design using inferior parts, issues with printer kits arriving missing bits and poor customer service. It was enough to make me look elsewhere unfortunately.

can honestly say I havnt really had any of that, tbf you';ll always hear the bad about anything you look into, if it works well and as it should there';s really no reason to say anything about it on the net :hmm:

I cant comment on the rest of their range but the I3 pro B was well worth the small cost, only really had one issue with mine and that was a slightly bad formed small acrylic frame part which was easily replaced with a printed part.

nice strong nema14';s
Mk8 extruder (which has so far matched my e3dv6 for print quality)
quiet and smooth movement
tons of mods available as its a prusa based design
and Geeetechs take on the 2560 all-in-one controller has been a pleasantly capable surprise.

It';s all a bit confusing. I believe your positive experience whole heartedly. But I also believe that some, if not most, of the negative stories about geeetech have some meat to them too. Different people, different experiences I guess. For example, it';s even been mentioned by a respected builder in this thread that they wouldn';t touch geeetech again. And Ive found so many horror stories around the net about their gear. But, as you say, people generally tend to report the bad, not the good and definitely not the average!

Saying that, if it were a question of which kit car should a newbie buy as a quality starter model there would be only a handful of models that enthusiasts would recommend due to their knowledge of the hobby. I had hoped there were 3-5 or so printers that were obvious choices as an introduction into the 3d printing hobby, and that came widely recommended from seasoned enthusiasts. As had been mentioned it shouldn';t really be a case of ';buy what works for you'; because newbies don';t know what works for them. That';s the real reason for this thread.

I';d guess some peeps will disagree and think every interested party should learn from their own experience / the hard way etc. And I mean no disrespect to anyone at all. I';ve learned loads from people sharing some excellent info on this thread and really appreciate all the input. It';s been fantastic. I';m just a little disappointed that there isn';t an easier answer to the op.

I plan to build a simple box to sit over the M150 for abs printing. Looking forward to Christmas to see what it can do.  ::)

Ikea Lack table fits great over I3';s, the m150';s dimensions are very similar to my own I3 Pro B';s and even my own designed RepRap I3 and both sit comfortably under a Lack table.

you can either cover three sides with board or use some clear acrylic for that all-round view effect.

alternatively you can flip the table on its back and put another piece of acrylic across the top so you can also look down on you printer while its doing it business.

not only cleans up everything but it does a crackin job of maintaining the ambient air temp around the printer meaning you dont have to worry about the occasional chilly draft screwing up you heatbed temps. ~~

Great idea, thanks.   ~~  I';ll be popping to IKEA for the christmas tree in a few days so I';ll probably pick up one of them tables too.  I like the idea of a large viewing area.  I';ve got some acrylic lying about so I';ll probably use that.   :smiley:

Esun PLA is amongst the best Ive used in their translucent and semi translucent range, surprisingly hard-wearing and less brittle than the cheaper PLA knocking about.

a good PLA alternative is Excelvan which is what I primarily use when working with PLA or even Flexi-Pla, their ABS is pretty good quality too but as your new to 3d printing Id stick with PLA before you decide to move onto ABS, unlike PLA ABS can be temperamental and requires a little more careful tweeking and bed prep to get truly decent largish prints , PLA on the other hand is a very forgiving material to work with and will often supply fine quality prints even on the most basic of settings. ~~

Cool, I';ve bookmarked Excelvan to try next.  I bought one or two reels of ABS (one black, one red iirc).  I plan to make a frame and some multi rotor parts, and buying PLA and ABS together allowed me to save a little on postage, but I';ll defo get to grips with the new printer using PLA first.

I'm still looking after over a year ! I've got my eye on one but there's a choice between a soft touch display control panel and the ordinary scroll wheel push type. The soft touch panel is the later design but costs £30 more and it comes with auto level. Would it pay to get the auto level ?

If your new to 3d printing then a pre-installed auto-level setup will ease the learning curve you'll be on certainly, us long term printing veterans have long since learnt the art of getting a level bed without AL so it often appears that its not as big an issue as everyone makes out but its very likely the most time consuming "tweeking item" on any non-AL printer

Levelling a bed isn't difficult and only takes a minute or two to get right.  In general it doesn't need to be redone that often (varies on the physical size and weight of prints you do and the way you remove them from the print bed) as long as the nozzle height and the print beds sprung screws are correctly taught and set up nicely from day one.

But it is boring and can slow down progress. Assuming theres no mention of problems associated with the touch screen I'd definitely recommend spending the extra £30 and saving yourself the hassle of bed levelling.

There's not much info on the soft touch control as it's just being introduced. Its on the Tronxy x5s and x5sa printers, I've looked at Deltas, bit big for me, Ctc types but I fancy this box extrusion type, you can do lots to it.

I'm still currently running my little HK Fabrikator II Mini.  I bought it while it was on one of HK's "OMG, were overstocked and the b*ggers are not buying any" sales, a very hefty discount it does not have now.

It worked well straight off but after a dozen or so prints a flanged gear wheel threw off the flange. As HK support seemed in the middle of hibernating through an Ice Age I stripped it out, superglued it back, and its been OK ever since. I did eventually get sent some gears but by that time I'd decided my repair was OK.

While I didn't have any obvious bed levelling issues, I certainly had issues with bed adhesion, which did not seem to be levelling related, at least not solely. This intermittently was quite frustrating.

Eventually the penny dropped and I realised that the small amount of expelled filament between the head starting to move and the head getting across and down to the start point was not helping, and not being able to stop it happening I used to use a paperknife blade to wipe it away just before it got too low to access.

This worked, and more recently it seems to have stopped doing that, not that I have altered anything.

Its got quite reliable (famous last words), but if anything, bed adhesion is now too great and removing the print is sometimes quite tricky!!   :rolleyes:

The only mod I have done is to replace the reel holder with a 3D print one that allows the slightly larger ESun reels to avoid jamming on the feeder block.

I'm using HK, ESun, and Polymaker reels, all PLA, with no effect on changing between.

I'm going to be buying new again in the next couple of months, at least 250x250x250 this time, and multi material capable.

It's SO difficult to see wood for trees on what's "best", and at the moment I'm tending towards the Original Prusa i3 in the latest Mk3 form.

Post by: shawdreamer on March 04, 2018, 16:56:01
hmmmm to be honest the more I look at that MK3 the less I can actually see the point, or for that matter the justification for calling it "the mk3".

by my eye, even on the most fundamental scale its just a standard "MK2" with a few of the mods people thought up and perfected slapped on it, there's very little if not anything NEW about it (except maybe a higher price tag)

personally Id just stay with a Mk2 clone and add the mods you want yourself, you can pick up a cr10 for half the asking price of a mk3 and still have money left over if you then paid out for high quality add-ons.

With a little experience under your belt you could even build a printer to match the mk3 from scratch for a fraction of the cost, my PolturXL can run a 300x300 heatbed (using a silicone heatpad it puts any alu heatbed to shame too), I recently converted the bed to a magnetic setup too, It can run just about any extruder I care to chuck at it, from dual to diamond head, Its ran every filiment Ive used (from PLA to PETG 190c-260c), the list could be endless but If I totted it all up on cost to build (including mods I tried and discarded) Id say Ive spent about 300 notes getting it to were it is now. :hmm:

The mk3's a pretty big step up from anything that's gone before it. It's genuinely the most advanced 3d printer available on the hobby market right now. It's a completely new design compared to the mk2S and it's the first time you can't fully upgrade a previous model to the newest version via an upgrade kit.

The mk3 has a new box mount frame that highlights how outdated the mk2's frame has become. The onboard sensors (that actually work) are phenomenal and almost a must for serious makers and commercial print farms. For most people there's no way they could build a 3d printer from scratch that rivals the mk3. And it wouldn't come with the renowned support or access to off the shelf parts and free specific firmware updates. From everything I've watched and read it's quite simply the cheapest, best equipped and most reliable 3d printer on the planet.  ~~

I'll hopefully be able to confirm all this when my mk3 arrives later in the month or early April.  :crossfingers:

I bought direct from Joseph Prusa Research.  They've got a 4-6 week backlog at the moment (better than the 2-3 month backlog that was in place after it launched last November) but they're printing and building kits and pre-assembled machines to order as quickly as they can.

I emailed them a question and they got back to me within 3 days with an answer, and they've supplied me with a couple emails already with info about the machine and a new firmware that's just been made available (guessing my machine may already have it installed when it arrives).

Know of build times, no problem.  I'll soldier on with my little Fabrikator!

My research has seemed to show that Prusa have a noticeably more pro-active approach to customers than many of the other makers, who seem not to bother with such frippery.

The "this is a developed product" approach rather than "been there, but this is all new" is attractive to little old engineer me.

I draw the similarity with MMW and other motor/etc suppliers. MMW isn't the cheapest, but Benedikt is very active in customer service and that has a value.

+1. The Crealty CR-10S is the printer I'd have bought if I'd not decided to go down the official prusa route. It's got a huge build volume for the money (and can go even bigger for more ££) and it gets rave reviews for ease of use and great print quality. There's a ton of modifications available for it too. As long as your ok with tinkering and figuring things out yourself it looks like a great machine.

While I've been looking I see mentioned that most printers work with filaments at 1.7mm but work out twice as expensive than 3mm, so is it possible to upgrade extruder and heat head thingamijigs or is 3mm filament just for industrial stuff ?
Title: Re: WHICH? 3D Printer
Post by: nate80 on March 06, 2018, 13:17:57
As far as I'm aware the difference is marginal and plenty of people are migrating from 1.75 to 3mm due to the cost savings.  The extruders stepper motor has to work a little harder with 3mm and slippage is slightly more likely (though not a problem if everything calibrated properly).  Most 3mm setups are Bowden style.  1.75m is a little easier to find and buy.  I don't really know of any other significant differences or issues.
Title: Re: WHICH? 3D Printer
Post by: Doug on March 06, 2018, 14:45:29
Be careful going to 3mm filament.  it stems from the very early days when there was no real filament as such and people used to uses trimmer plastic. 3mm is becoming less popular and I suspect that is why it is reducing in cost cos everyone is trying to get rid of stocks they hold I can see it disappearing almost totally in the not to distant future although there will alway be a requirement for it for those who print very large stuff and then it will be at a premium.

Also consider that you need much more powerful extruders to be able to push that size of filament thru what is effectively a tiny hole.
Title: Re: WHICH? 3D Printer
Post by: nate80 on March 06, 2018, 16:20:58
I've not heard that before.  Guess we'll have to wait and see if 3mm (actually 2.85mm, I think?) dies any sort of death as I've read plenty of discussions and reports of people jumping the 1.75mm ship for 3mm over the past year or so.  The reason was mostly cost, which hasn't changed relative to 1.75mm prices for some time afaik.  I understand the cost difference between 1.75mm and 3mm is vast in some areas of the world too, so that can make a big difference to the products longevity.

It'll be interesting to see if all those loyal to 3mm will be forced to swap over in the near future.  Personally, I'm not so sure.  3mm requires more effort on behalf of the stepper motor but it also feeds slower.  With the right nozzle it can obviously output far denser filament runs so can produce suitable models far quicker than 1.75mm, so that's another huge benefit.

Personally I'll be sticking with 1.75mm as it answers all my needs ok, but if I were looking to print large models and big runs frequently, and if money was a concern (the more you print the more the cost matters) I'd seriously consider 3mm.

MMMM, interesting.

Have just been searching to buy PLA 1.75 and found TONS of 3mm on sale but little 1.75 available. HobbyKing as just one example, loads of 3mm in PLA, ABS, etc.
Title: Re: WHICH? 3D Printer

there's another factor to take into account if considering using 3mm, its doesnt like being pushed through any extruder lower than 0.4mm, even with a strong motor behind it the stock heater found in most printers just cant keep up with the sheer volume of filament that has to be melted fast enough to pass through the extruder smoothly, from personal experience I found the average extruder temp for 1.75mm abs was notably lower than 3mm as I had to increase temps to give the 3mm abs a better chance of hitting its ideal melt point before trying to pass through the tip.

Even with the increased temp and stronger stepper I struggled to get consistency on any print using a 0.3mm tip, It did improve when I swapped it out for a 0.4mm tip but the big downside imho was the loss of print quality and accuracy in small parts, larger prints did see a print time reduction but the quality loss alone made the time saved unjustifiable.

for the sake of saving yourself a couple of quid a roll I honestly cant recommend using 3mm at all, 1.75 is just better supported in general and produces much more consistent results, thats all just based on my own experience though so feel free to give it a bash if all your doing is mid-sized/large prints that dont really need high detailing. :shrug:

Well I am still looking at the Tronxy x5sa and the Anycubic linear plus delta, both have heated beds although the Tronxy needs a 24v upgrade to get higher than 60c. Brain hurts  :banghead:

just run the HB off a separate 24v/variable PSU through a expansion board.

.... hold on

stock setup only does 60c?, wtf is the point of that????

Looks like without insulating under the heated plate it won't go any higher and it takes forever to heat up.

In that case just put a silicone heatpad under the build bed and not even bother wiring the stock bed,  even the BG 12v 200x200 I use can make my build deck hit 130c in about 20mins

I’ve seen a few people use old cut down mirror glass for replacing warped heat beds. I can’t make my mind up which one to go for. Are deltas supposed to be less accurate and better for speedier prints ?

MMMM, interesting.

Have just been searching to buy PLA 1.75 and found TONS of 3mm on sale but little 1.75 available. HobbyKing as just one example, loads of 3mm in PLA, ABS, etc.

Hobbyking have been out of stock of 1.75mm pla for ages. I've been waiting for a restock for a couple months now. I think their shortage is to do with economics. Hobbyking's stuff is super cheap compared to the majority of other retailers (who have recently been edging prices upward). I believe they can't get it from their suppliers because their suppliers are selling it to the competition for more money. There's also a slight shortage in global plastic production at the moment.

1.75mm machines are most popular so filament for those will have sold out first. Hobbyking and other suppliers may not be getting supplies of 3mm right now either but their stock levels could be high enough to outlast through drought.

I know nothing about plastics but maybe it's a good time to get into plastic recycling as nobody wants the waste. I've seen a 3D print pen that runs on plastic bottles whilst goooogling around.

I've spent a little time looking into the potential of recycling old PLA prints. It'd be great to be able to turn old models or waste back into usable PLA filament. Unfortunately, for hobby users, the technology just isn't there yet and whilst it's possible to purchase equipment that can grind and re-form filament it's slow and very costly, so I'll be sticking with wincing every time I throw wastage in the bin for the time being.   :-/

Does anyone have experience with the Malyan M200
I'm after a small, simple 3D printer
It wont be used for more than small Quad parts - ie I cant see anything bigger than 2-3 inches being printed at this stage.

build it your self theirs some great guides out there you learn so much and the first time it breaks down you know how to fix it and if your lucky you can sell for a prophet
i've built two now if you like tinkering then its good and easy 

id recommend something like this remember to have lift lid and door its cheap it easy to store as its a box and it keeps all the mess enclosed and if the roof and door will make great for stopping drafts killing your prints as that can be a big issue later on down the road honestly if your going to do it build it

yes there was lol

its basicly a ramps board running everything theres lots of information on ramps there old and noisy but still do the job great place to start inexpensive 18 dollars for the hole brain run it with a raspberry pie using octo print for web contorl of your printer from anywhere on your network again octo print can be added in at a later date

printing area of 200mmx 200mm is normal size so and print bed only goes up and down  very doable

prusa i3 are very good machines lots of blogs on them like this 1 and 200 quid if you dont maind 30 day post from china are very doable id print the parts you need but i no longer have my printers i sold them 
but have a look at this

and there more blogs out there
 wood and threaded rods  can be got from most diy stores 5mm thread rods use banggoods aliexpress same for soomth rods get the hardened chrome smooth rods  take you time find out the datail the prusa i3 is a good place to start as its one of the most documented builds going
