Most magnetic + heat resistant!
High Density Stainless Steel HTPLA Filament has 70wt% 400-series stainless steel for the most magnetic HTPLA 3D prints and 3x the temperature resistance (when heat treated) compared to PLA-based metal filaments.
Protopasta Stainless Steel HTPLA is ferromagnetic. Yes, 400-series stainless steel is magnetic! Encapsulated in plastic, the steel powder creates a matte, cast-metal finish as printed, but can be brushed, sanded, or polished for a real metal finish.
Featured in September 2025's Endless Exploration Subscription Delivery. More about the contents in our EX10 blog. You can also visit our blog for more about metal finishing and heat treating.
