Carbon Fiber PETG *new low price*

*New low price* ~20% stronger + 90% stiffer than PETG w/o fibers. High quality, US-made PETG just got more affordable! Compare to Atomic, Prusament, and Pantheon PETG Carbon Fiber, but with Protopasta design intent + quality. 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 PETG 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 235+ 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 profile and adjust if/as needed.

Like other 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.

PETG-CF is more flexible and ductile than Carbon Fiber PLA and HTPLA, but less stiff and strong. PETG-CF has a thermal performance in between PLA and heat treated HTPLA. Consider PCTG as a PETG alternative for improved durability and chemical resistance. More details in our blog.

Protopasta Carbon Fiber PETG includes:

• 100% new PETG, made in the USA for the highest quality result
  
• quality ingredients plus in-house processing for curated chemistry
  
• processing from 235+ C @ 2 cu mm/s volume rate, 70+ C bed
  
• less rigid than PLA and HTPLA for more flex before break
• more heat resistance than PLA, but less than heat treated HTPLA
