I have a Lulzbot Taz 6 and wanted to 3D print a part that is currently made from TPU (Thermoplastic PolyUrethane) with a shore hardness of 70A. I was looking to buy a filament for this and found NinjaFlex (https://www.lulzbot.com/store/filament/ninjaflex). Is this the appropriate filament or is there something better out there? Can this be used with the Taz 6?
