Metal Composite HTPLA

Now available in 1kg size. Protopasta Stainless Steel PLA filament 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. Using real steel powder, this premium, metal-filled steel PLA filament is perfect for jewelry, costumes, props, figurines, crafting, robots, or any other 3D prints needing a truly stainless steel finish. *Steel PLA made on and after Feb 27, 2025 (lot number X50227BXXX) is made from 400-series stainless, instead of 300-series, just like our new steel colors, gold, burgundy, and blue. Also, A identifies 300-series and B 400.
