CC3D 72D Flexible TPU Filament Black 1.75 mm 1 kg 3D Printer Filament High Hardness Toughness TPU Filament FDM Printer 3D Printing Material Comparable to Nylon Filament Black

The best thing about this filament is the layer adhesion and that even thin parts, which would be fragile in most other common filaments are basically indestructible. you can bend it as much as you want, keep hitting it with a hammer and the part does not seem to care... also it seems to be way more flame resistant (but not flame retardant/self extinguishing) than PLA/ABS/PETG....The second best thing is that there is basically no smell when printing. I can still smell e.g. faint ABS smell which was printed a week before this in the same printer, but nothing for this filament.This is not a filament to print decorative things or to substitute either some stiff or "rubbery" parts. This is for very resilient functional parts with some flex.I had troubles when trying to print like TPU. When treated like nylon, I finally started getting successful prints. 235C hotend, 75C bed, enclosed, no part cooling apart from overhangs was the config which works for me. I have no troubles printing ABS with no warping, but had to apply substantial layer of gluestick on top of my PEI sheet to prevent severe nylon-like warping.Drying the filament is also a must and although maybe not as bad as pure nylon, it is worse than other TPU regarding water absorption. It also has much higher stringing than other common filaments and since this filament is not too susceptible to heat, it is not as easy to remove the strings with a lighter/heatgun.This filament is much stiffer than your standard TPU and can be printer almost as fast as PLA/PETG limited mostly by the reduced cooling.

話にならない。235度で使うと書いてあったが、290度でないと溶けない。ノズルが一瞬で詰まり、全く出てこない。（プリンタ側は正常）

TPUと書かれていますが印刷すると硬く、普通のPLAなどと同じ素材です。
