A very nice looking material. Heavy with a metallic aspect

Color: Gray

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.

These 500G spools are shipped on the industry's only fully recyclable corrugated paper spools with no metal or plastic parts. These extremely high quality spools are rigid, lightweight, attractive, and eco-friendly. They also have a larger than normal inner core improving printability of the last few layers of Material, especially on 2.85mm diameters. The different designs on each spool are actual drawings, schematics, and Code from the equipment we manufacture your filament on. Enjoy!

This stainless steel filled PLA can be Polished to look like Polished metal! it is also 2X the Density of PLA for substantial feeling prints

Material is matte Gray with a cast metal look. Can be Polished with proper Tools to a semi-reflective finish

Processing is comparable to standard PLA. No heated bed required. Process may be less consistent on smaller nozzles (<.4mm) andor bowden Type machines

We recommend printing this material at 190c-230c using a 4 mm or larger nozzle. Please Note that this filament is more brittle than normal PLA and requires more careful handling to prevent breaking

Designed and manufactured in the USA with quality and customer service as a top priorities. Usa sourced packaging and labor
