Thats good news, thanks

RE: Can the Mini print TPU ?

what settings?  noobie here, bought the mini to print TPU FPV drone parts... TPU is pretty much my primary need... as a noob and with no presets, I'm worried about digging through the gears to pick out filament.

Any pointers on how to best achieve success with TPU on the Mini ?

RE: Can the Mini print TPU ?

I was honestly surprised when I threw some tpu at my mini, and it just printed it without any problems. My one piece of advise would be to print nice and slow. I usually run mine at around 50mm/s while printing 95A, but ymmv.

RE: Can the Mini print TPU ?

Well I just went for it. Heat at 215.  20 (.20? Sorry) mm speed.  Tpu spool temp was 200 - 220. Lots of strings, but usable print.  95a TPU.

RE: Can the Mini print TPU ?

what about Flexfill 98A? I haven't seen a profile for it.

Thank You

There is a profile for Fillamentum Flexfill 98A in Prusa Slicer. I've used it with my 95A and it works just fine.

RE: Can the Mini print TPU ?

I use sainsmat TPU and it worked great on my mini. It has a profile in prusaslicer. I set the temperature to 215C and changed retraction length to reduce stringing. Mostly I use the satin sheet or for models with larger base area the steel sheet. In fact it prints more easily then regular (prusament) PLA. Never had adheasion or extrusion problems. Stringing is a topic for complex parts, but it is manageable.

When I load the filament I choose "PLA" from the menu, because the sainsmart tpu didn't need high  temp.

see some of my tpu prints here (the "red" ones): https://www.prusaprinters.org/social/113164-antimaterie/prints

RE: Can the Mini print TPU ?

For others who may need it spelled out like I do, use the "Configuration Assistant" under the "Configuration" menu to add new filaments. Jump to the "Filaments" section on the left-hand side, then the TPU filaments exist under the "FLEX" type. My brand wasn't there, but it's a lot closer than just guessing on speeds and feeds.

RE: Can the Mini print TPU ?

Yes, and if you have a filament that is listed in the filament profiles, it is pretty much plug and play.  I printed some Fillamentum FlexFill 98A today for the first time.  The only thing i did was loosen the filament idler screw a couple of turns and sliced with the standard filament profile and pressed go and got multiple perfect prints in a row...  Amazing!

RE: Can the Mini print TPU ?

Yes it does support it.

I used Polymaker Polyflex TPU95.

I went to their website, download the mk3 print profile and modified it for the mini. it work immediately. I used the satin bed plate. and the filament was keep at 13% humidity.

The Mini is a way different printer than the MK3. Because of the Bowden tube it oozes more and needs to print slower, especially with soft stuff. I started with the Prusa Slicer TPU profiles and have good results, but others pretty much universally like the Bondtech extruder to improve printing of soft stuff like TPU, especially for the softer TPUs.
