Bambu PA-CF – PA12 with 20% Carbon Fiber

Bambu Lab's PA-CF combines a PA12 matrix with 20% short carbon fibers for maximum stiffness and heat resistance up to 180 °C. Requires a steel nozzle and a heated filament drying chamber (active during printing). The highest-performance FFF material for load-bearing structural parts in mechanical engineering.

Compliance Evidence

RoHS

Free of hazardous substances (lead, mercury, cadmium, hexavalent chromium, PBB, PBDE) per EU Directive 2011/65/EU. Safe for commercial use in the EU.

Evidence: Documented via Bambu RoHS PDF (Bambu Material Safety Portal)

~REACH

⚠ Partially documented – SVHC statement available, but no complete REACH conformity declaration on file.

Evidence: Only documented if PA-CF is explicitly listed in the Bambu Material & Chemical Safety/REACH list. When in doubt, treat as undocumented.

The evidence listed applies to the filament or raw material per manufacturer documentation. Regulatory clearance of the printed final product – particularly for food contact, medical devices, electrical applications or UL-relevant parts – is not automatically included and must be evaluated on a project-specific basis. Technical machine assignment is handled internally.

Material Profile

PA12-CF is the flagship material in this database. Choosing polyamide 12 (rather than PA6 or PA66) as the matrix is technically motivated: PA12 has the lowest water absorption of all polyamide types (~0.3% equilibrium vs. ~3% for PA6). This is critical for dimensional stability and mechanical reproducibility in the FFF process.

Why PA12-CF for Structural Parts?

PA12-CF combines the lowest water absorption of all polyamide types (~0.3% equilibrium) with the reinforcing effect of 20% short carbon fibers. The result: dimensionally stable parts with reproducible strength values – even after humidity cycling. We ensure process quality through active material drying.

When Is PA12-CF the Right Choice?

Only when all of the following apply:

  1. Temperature continuously >100 °C or briefly >140 °C
  2. Tensile loads >50 MPa expected
  3. Weight optimization is critical (modulus/density)
  4. Tribological stress (sliding, abrasive load)

For brackets, consoles and prototypes, Prusament ASA or BASF Ultrafuse PET is the more economical choice.
