Flexible filaments are chemically and mechanically resistant materials. Individual layers adhere strongly together and there is excellent print bed adhesion (applicable to TPU and TPEE). Flexible filaments are made of TPE (thermoplastic elastomer) but are distributed under various names such as TPU, TPEE, etc. Generally, the more flexible the filament, the more challenging it is to print.
Flexible filaments are highly wear-resistant, remain flexible even in cold environments, and show great resistance to various solvents. Dimensional stability is excellent with little to no shrinkage or warping. Their toughness and tensile strength are exceptional, allowing 3D printed parts to withstand high stress before breaking. These properties make them suitable for printing spacers and other highly stressed parts. With the right print settings, you can print stamps, RC tires, shoe soles, belts, and more.
