Fabru Compression spring extruder (flexible materials)

This pressure spring is ideal for 3D printing with purefil ceramic filaments as well as any elastic materials such as TPU, TPC, PLA soft, etc. The reduced clamping pressure significantly decreases the stress on the filament, allowing for reliable processing of elastic materials even with standard Bowden extruders. This pressure spring fits into almost any feeder from well-known manufacturers such as Creality Ender 3, Ender 3 Pro, Ender 3 V2, Longer3D LK1, LK4 Pro, LK5 Pro, Cube 2.0, and many more.
