Heated bed and all-metal hotend recommended!

Processing is more challenging. For best results, a heated bed is required to control warpage and improve layer adhesion. Cross-sectional area should be minimized.

  • Available in 1.75 mm and 2.85 (3) mm diameters, black or natural color
  • 500g is on a 8" diameter spool

PC-ABS is moisture sensitive. Even when stored in a bag with desiccant, drying in an oven for ~ 1hr at 85C-95C may be required for bubble free high strength prints.

In our experience, good results are achieved when printing small parts at 270-290C on a heated bed at 110C up to 140C. For larger prints with good layer adhesion and minimal distortion, an enclosure is ideal.

The Best

Great product. All their products print great. Really wish they would offer a PLA Pro/+ option as well as a refill option that doesn't include the spool at a slightly discount price. Protopasta is the best though

Protopasta PC-ABS is incredible!

Protopasta's PC-ABS is one of my all-time favorite filaments for detailed, functional parts. It is incredibly strong, heat resistant, and has an incredibly smooth matte finish that makes for really polished, professional looking part.

Very impressive

I've had difficulty printing pure ABS in the past (warping with reputable brands). Using an Ender3 w/ bondtech direct drive and e3dv6 hotend I was able to print this flawlessly. For my first print I threw caution to the wind and went with a rather complex geometry and had no issue. Highly recommended.

Great results at very high temperature

Printed at 268*C — as hot as my printer goes. Used glue stick on glass for adhesion. Produced a great temperature-resistant motor mount for 3D printed electric RC plane. No warping. Great layer adhesion. Nice looking part.
