FiberFlex 30D

FiberFlex 30D - bardzo miękki filament elastyczny

FiberFlex 30D is our proposition for people interested in 3D printing with flexible filament of reduced hardness. This is the second filament from the FiberFlex family, whose high flexibility allows you to create 3D prints in projects that require rubber-like properties. Therefore, any project requiring resistance to bending, crushing or stretching may require the use of this material.

3D printing with flexible filament of Shore 30D requires some experience in this field and an appropriate 3D printer. Therefore, this extra soft material, like TPU filaments of similar Shore hardness, may be problematic for beginners. It highly recommended to use direct drive extruder and reduce speed. Reducing the pressure on the extruder gear may also help to achieve a successful print.

From other proposition of flexible filament, with hardeness grater than 30D, you may also be interested in Fiberlogy FiberFlex 40D and Fiberlogy MattFlex 40D.
