TPU that works in AMS coming

[Hank]

Interesting but also uninteresting as well.

Thermoplastische Polyurethane have interesting properties that are not just based on their rigidity - That’s why I keep my eyes open for TPUs that get even harder than 58D which you actual can get.

There are already methods for getting to 58A with real TPU with under-extrusion …:

The Ultimate TPU? Achieve Shore Hardness Down to 55A and Beyond, ON YOUR PRINTER.

The problem still is at Bambulab only which simply reject all types of TPU without apology as soon as you want to load it into the AMS - So the solutions have been there for a long time:

Printing TPU with AMS

Bambu never put a blanket ban on just any TPU: Their wiki says the printers can handle 80A/30D or harder, and the AMS can handle 55D/98A or harder. There are some reddit threads where people have listed brands/types that worked or not. I’ve been meaning to experiment with it but haven’t had the time yet. I noted from some such thread that I might want to try Overture High Speed TPU 95A, Extrudr Flex Hard TPU 58D and/or Priline black. My use case is printing seals in place. I do have some CC3D …

And because of the poor description of this new “Big Tree Tech” fillament, the fillament is useless at all… UV resistance? Resistance to solvents? Splitter properties? Standards met for possible residues? And so on… They can sell this on Amazon as far as I’m concerned. At least for me, just good enough for the trash can due to missing specification and 3 batch checks…
