Ships next business day!
1KG roll of Carbon Fiber PC+
Orders placed by 3pm (EST) are shipped same day!

Please note:

The carbon fiber powder is hygroscopic, meaning it will absorb moisture if left in a humid environment. If it does absorb moisture, you will notice weird artifacts or difficulty printing. To fix this, we recommend dehydrating the roll in a food dehydrator or via an oven before printing.


PC+ (PolyCarbonate)

Polycarbonate is an extremely strong, impact resistant thermoplastic that is widely used in industrial applications. This material does not shatter like plexiglass. It tends to bend and deform similar to hard rubber until it eventually breaks. PC absorbs a lot of moisture in the air. It is a hygroscopic material, and it is best to store in an airtight container when not in use. Even during use the material can become unprintable within a 24 hour print if in a humid environment. Therefore, keeping in an airtight container during printing as well is ideal. Dry filament will print more clear. Filament that has absorbed moisture will print white as well as pop and bubble during the print.

Our PC+ differs from pure PC as it contains additives to make it easier to print reliably.


  • Biocompatible and can be sterilized
  • High strength and heat resistance
  • Malleable while cold and can be bent without cracking
  • Exceptionally durable
  • Use Acetone for a polished finish.
  • Carbon Fiber filled for stronger prints!

    Amazing Stuff!

    This stuff is amazing! Definitely my new favorite when it comes to strong functional prints unseating XT-CF20 as my goto filament. With PC filmanets I typically print with a 2 layer brim and I have to say you can definitely tell there are actual fibers instead of powdered fiber because the brim doesn't tear off as easily. Love this stuff!!

    CF PC+

    My favorite structural filament to print with, prints perfectly every time without me intervening or having to do anything other than take parts off the build plate. I've gone through an entire roll printing small precise parts.
