ColorFabb BrassFill combines PLA and Brass Powder to bring you a premium filament that offers a wide variety of uses. BrassFill prints are completed with a coloring that is very similar to gold. Giving BrassFill prints a polished finish with bring out the metallic shine. Since BrassFill is a combination of PLA and real Brass Powder, it feels like a denser, heavier substance that is very convincing that it is pure Brass. When brassFill is used on an FDM 3D printer it comes off the print bed with a greenish matt surface, which is similar to that of the bronzeFill. Once polished, it displays an appearance that looks like gold (as seen in the 3D printed ’0Lgold bars’0M you see above).
