So I normally print high temp filaments across the board but recently something I designed really only worked best in TPU for it’s intended purposes.., therefore I’ve never had any of the A series or any printer without a heated chamber of some sort.
I did a few production runs of TPU in H2C’s and D’s using external spools with ball bearings etc., and it worked great.
But I didn’t want to tie up those machines with TPU so pulled the trigger on the Mini. Well, just finished the 1st print on it with TPU, talk about perfection!
I honestly have NO IDEA how they can sell this thing for $219 right now. Assembly and unpacking was 5 minutes. Just an absolute INSANE bargain for what you get.
Since this TPU product line I’ll be doing in mass quantities, I’ll be ordering several more of these machines soon.
I just wanted to thank the folks at Bambu for making such an amazing little machine and an absolute INSANE price point for what you get.
Absolutely LOVE my A1Mini. And yes, that thing giggles at TPU. Just an amazingly versatile little guy and it prints it all spot on. Such a cool printer.
I use a lot of TPU and I switched to the variable shore filaments. This makes all the print problems go away.
The stuff is rigid, and when heated it foams, and the bubbles soften it. It works in the printer as it’s rigid as it’s pulled by the extruder, and then you set the nozzle temperature to foam it to whatever softness you want.
I was finally able to print 60A shore tyres with this stuff.
I’m curious how this type of filament would hold up in a manufacturing / industrial environment.
I really like the siraya tech stuff as it has the flexibility but it’s rigid at the same time. Everything else I’ve tried, tries to do this with formulations of PETG or other hard plastics and testing the part shows they are much weaker in comparison.
