Choosing Nylon 11 CF Powder
A Fuse-series carbon-fibre PA11 for stiff, lightweight functional components where black as-printed appearance is acceptable.
- Consider it for
- Stiff jigs and fixtures · Lightweight brackets · Thermally demanding functional prototypes
- Tradeoffs
- CF reinforcement improves stiffness but reduces compliance and brings orientation sensitivity. It is still a printed polymer composite, not a blanket replacement for metal or a certified conductive part.
- Design and validation
- Keep loads in the stronger plane where possible, avoid sharp internal corners, and validate loaded threads, inserts and fatigue features on representative production orientation.
- Finishing
- Black is the inherent as-printed appearance and is not a dye base. Any abrasive cleanup may change the surface fibre appearance.
- Before choosing
- Does the geometry need compliance that unfilled Nylon 11 offers? Are high temperature and rigidity worth the lower strain margin?

How to interpret this data
The TDS says properties may vary with part geometry, print orientation, and temperature.
The solvent section says printed and post-cured but defines no SLS post-cure. This wording does not establish an SLS post-cure requirement.
This TDS does not publish powder moisture, printed-part water absorption, or a UL 94 result.
Formlabs Nylon 11 CF Powder — frequently asked
What is Formlabs Nylon 11 CF Powder used for?
A Fuse-series carbon-fibre PA11 for stiff, lightweight functional components where black as-printed appearance is acceptable. Consider it for stiff jigs and fixtures, lightweight brackets and thermally demanding functional prototypes. CF reinforcement improves stiffness but reduces compliance and brings orientation sensitivity. It is still a printed polymer composite, not a blanket replacement for metal or a certified conductive part.
What should I validate before using Formlabs Nylon 11 CF Powder?
Keep loads in the stronger plane where possible, avoid sharp internal corners, and validate loaded threads, inserts and fatigue features on representative production orientation. Does the geometry need compliance that unfilled Nylon 11 offers? Are high temperature and rigidity worth the lower strain margin?
How can Formlabs Nylon 11 CF Powder be finished?
Black is the inherent as-printed appearance and is not a dye base. Any abrasive cleanup may change the surface fibre appearance.
How should I interpret the published values for Formlabs Nylon 11 CF Powder?
Fuse 1+ 30W; specimens conditioned at 23 °C and 50% relative humidity for 7 days before testing. Tensile strength, tensile modulus, and elongation report X, Y, and Z values. Flexural, impact, and thermal rows do not state an orientation. Read each value with the stated method, specimen preparation and conditioning.
