Carbon Fiber PLA
CF-PLA (Carbon Fiber Polylactic Acid) is very similar to Standard PLA but is blended and composited with carbon fiber strands. This reduces the plastics tendency to warp in addition to adding rigidity. However the reduction of flex causes this material to be very brittle. CF-PLA also leaves your prints with one the best surface finishes out of all the materials offered.
Ease of Use
Printing at a slow speed is recommended.
