Which Material Do I Need?

Carbon fiber fill makes PETG-CF significantly stiffer than standard PETG, but color options are limited to black — the carbon fiber content prevents pigmentation.

Glass fiber reinforcement improves stiffness and reduces warping on large flat parts, but limits color selection to neutral tones. If color variety matters, standard ASA is the better choice.

ASA-CF is the strongest weather-resistant material we offer. The carbon fiber fill makes it significantly stiffer than ASA-GF and nearly eliminates warping. Unlike most CF materials, ASA-CF is available in four colors — black, dark grey, light grey, and navy blue.

CF-Nylon is used in production automotive components where PETG or ABS would warp or creep under sustained load. Carbon fiber fill limits color to black — if color is required at this performance level, consider PC.

PC has the highest impact resistance of any material we print. It's the same base polymer used in safety helmets and riot shields — it will flex before it fractures, which matters for parts that take vibration or incidental contact.

PPS is one of the few FDM-printable materials that resists gasoline, diesel, hydraulic fluid, and most cleaning solvents without swelling or degrading. It's the correct choice anywhere a part will be in sustained contact with fuel or lubricants.

PPS-CF combines the chemical resistance of PPS with the stiffness of carbon fiber reinforcement. It's the closest FDM material to injection-molded engineering plastics in terms of mechanical performance. Used where both chemical exposure and structural load are present simultaneously.
