Proto-Pasta Stainless Steel PLA Filament


From the people who first brought you Carbon Fiber PLA, we are proud to present Stainless Steel PLA.

Protopasta was one of the first companies to bring a carbon fiber filled filament to the market.  Now they’re at it again with the stainless steel filled material.

Similar to the CFPLA, stainless is filled with finely milled and separated stainless steel particles.  The particles are small and well distributed so they will not clog your nozzle.  We’ve had excellent results printing this material in nozzles down as small as 0.35mm, but we recommend a minimum of 0.4mm.  Print at standard PLA temperatures.  Heated bed optional.

As printed, it’s a matte grey color.  However, after wet sanding and polishing to a smooth finish, it takes on a metallic shine.

Because stainless does not readily oxidize, this is easier to get a great shine than some other metal filled materials.

The stainless steel primarily gives a cool visual effect.  It is not conductive.  It does not increase strength.  However, it does increase density and  Some customers have observed that it increases wear resistance, but we don’t have any hard data on that yet.

IMPORTANT NOTE:  This material may be abrasive to your nozzle if printed in large amounts.  Consider a stainless nozzle.
