proto-pasta Stainless steel PLA is a dense Material that prints as easily as standard PLA but results in heavy cast metal looking prints that can be brushed, sanded, or Polished post-print to achieve amazing results. Perfect for jewelry, costumes, props, figurines, crafting, robots, and more! we suggest experimenting with polishing using our starter Kit and following Online videos at Proto-pasta.

in filament form, Stainless steel PLA is more brittle than standard PLA and requires extra care when handling. Processing is Comparable to standard PLA. No heated bed required. Process may be less consistent on smaller nozzles and/or bowden Type machines. We frequently print using direct-drive systems with 0.4mm nozzles, though suggest 0.6mm and 190-230c (standard PLA or a bit cooler) for the best experience. This filament is more abrasive than standard PLA. Be prepared to replace your nozzle and do 1st layer adjustment. Try a wear resistant and/or larger diameter nozzle for increased service intervals.
