Natural CoexFlex™ 60A TPU

**60A is very soft and can be challenging to print with.  We recommend a direct drive extruder with a contained filament path (it will squeeze out any gap it can) and a PTFE-lined hot end (it tends to stick to the walls of an all-metal hot end). Seasoning an all-metal hot-end may help.**

CoexFlex™ 60A TPU is, by far, the most flexible filament on the market. At Shore 60A, it is much softer than Ninjaflex or Filaflex, feels like a rubber band, and produces finished parts that are completely flexible no matter what infill density you use. Highly functional for applications that require stretch, flexibility, or compliance. (NOTE: Only printable with select printers capable of printing this durometer of filament. A direct drive extruder is required.)
