Black High Strength Carbon Fiber PCTG

~45% stronger + 250% stiffer than PCTG w/o fibers. High quality, US-made PCTG just got higher performance! The stiffest, strongest material of it's type that we've tested (see our comparison)!!! The value gets even better with free US shipping for orders $49+, 10% loyalty discount for orders $99+, and bulk discounts of 15-35% off starting at $249.

Like Carbon Fiber PLA, Protopasta Carbon Fiber PCTG is a performance value. It requires higher printing temperatures than Carbon Fiber PLA, but is still quite easy to print with bed temperatures from 70+ C and nozzle temps 255+ C. Higher nozzle temps improve layer adhesion, but risk overheating when printing too slow. We print up to 275 C, but 255 C is a good compromise. Start with a Generic PETG or PCTG profile and adjust if/as needed.

Like other PCTGs and PETGs, material can stick to the nozzle. Drying may not resolve this completely. In this case, consider reducing the flow rate to less than 100% to reduce buildup. Further, you might add a nozzle wipe at layer change with custom gcode.

Black High Strength Carbon Fiber PCTG is stronger and more ductile than Carbon Fiber PLA and HTPLA, but with a similar stiffness. It has a thermal performance in between PLA and heat treated HTPLA. Consider PCTG as a PETG alternative for improved durability, UV, and chemical resistance. More details in our blog.

Protopasta Carbon Fiber PCTG includes:

• 100% new PCTG, made in the USA for the highest quality result
• quality ingredients plus in-house processing for curated chemistry
  
• processing from 255+ C @ 2 cu mm/s volume rate, 80+ C bed
  
• more heat resistance than PLA, but less than heat treated HTPLA
