Flexible Filament Flexible filament is a category of 3D printing material characterized by its elasticity and bendability. Common types include TPU (thermoplastic polyurethane) and TPE (thermoplastic elastomers). Flexible filaments are used to create objects that require stretchability or impact resistance, such as phone cases, tires, gaskets, and wearable devices. Printing with flexible filaments can be challenging, as they require lower print speeds, proper extrusion calibration, and often a direct-drive extruder to prevent jamming. The flexibility and durability of these materials make them valuable for both functional and aesthetic applications in 3D printing, enabling designs that rigid filaments cannot achieve. |
