PLA Carbon Black Filament by Spectrum
is a modified, PLA-based filament blended with carbon fibers which contributes to a considerably higher rigidity, hardness and tensile resistance, while retaining low shrinkage and very good adhesion to build platforms typical for the pure PLA. 
The 10% addition of carbon fibre enables you to obtain matte surfaces of printed items, which greatly improves the aesthetic properties of printed items.
