MattFlex 40D is a flexible filament that stands out from other rubber-like filaments due to its matte finish, which perfectly hides layer boundaries and gives the model a unique look. The ability to stretch up to 6 times and 50% compression combined with high impact strength, chemical and temperature resistance make it a very versatile material for many applications.

Fiberlogy MattFlex 40D is ideal for printing models exposed to frequent impacts, bending or twisting.
