Flame retardant
3D printing

Flame retardant, certified thermoplastics made with the SLS or FDM printing process.

SLS Flame retardant Materials

SLS is used for both prototyping and small-batch production of functional plastic parts with good mechanical properties.

Benefits and Limitations

No support material required
Excellent mechanical properties
Can produce complex geometries

Higher cost than FDM
Longer lead times than FDM


Price $$$$$ Tolerance ± 0.3% (min: ± 0.3 mm)
Turnaround time < 5 days Wall thickness 0.7 mm
Max part size 75 x 55 x 55 cm Layer height 80 - 120 μm

Flame retardant Nylon

Flame retardant Nylon (SLS) are certified PA materials for consumer applications and aviation with great mechanical properties.

Material family

FDM Flame retardant Materials

FDM is the most widely available 3D printing process, mainly used for low-cost prototyping and design verification with very fast turn around times.

Benefits and Limitations

Fast turnaround times

Limited dimensional accuracy
Print layers are likely to be visible


Price $$$$$ Tolerance ± 0.5% (min: ± 0.5 mm)
Turnaround time < 2 days Wall thickness 0.8 mm
Max part size 100 x 100 x 100 cm Layer height 50 - 400 μm

Standard PEI (ULTEM)

ULTEM (FDM) is an engineering plastic with good mechanical properties and exceptional heat, chemical and flame resistance. Suitable for top-end applications.
