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! Usable on most PLA-compatible printers, such as Lulzbot, Makerbot, FlashForge, Dremel, Ultimaker, Printrbot, and more!
