Marvin looks great no matter what material he is printed in, but he is particularly stylish in Stainless Steel. Part PLA, part Steel, Proto-pasta Stainless Steel 18 (SSPLA) turns your affordable PLA-compatible printer into a jewelry, costume, prop, figurine, robot-making factory. Workable with familiar metal-working techniques, Proto-pasta Stainless Steel PLA can left as-printed for a cast aestetic and brushed or polished for a bright metalic look. Compliment the ageless elegance of SSPLA with Magnetic Iron (FEPLA) for a previously unacheiveable rusty patina. Creatives unite!
