Choosing Alumide
Aluminium-filled PA12 for rigid parts where the metallic gray appearance and higher stiffness are useful.
- Consider it for
- Display-quality technical models · Rigid housings · Stiff brackets with a metallic-looking SLS finish
- Tradeoffs
- Alumide is polymer filled with aluminium particles, not a metal part. Its low elongation makes it a poor substitute for ductile nylon or structural aluminium alloy.
- Design and validation
- Avoid thin, notch-sensitive features and validate any electrical, grounding or thermal requirement; filler does not make a part a reliable conductor or metal heat sink.
- Finishing
- The metallic gray is as printed. Blasting and clear coating may improve appearance, but confirm coating adhesion and any dimensional effect on a sample.
- Before choosing
- Is the requirement visual metallic appearance, stiffness, or actual metal performance? Would PA12-GF provide the needed stiffness with a different finish strategy?

EOS Alumide — frequently asked
What is EOS Alumide used for?
Aluminium-filled PA12 for rigid parts where the metallic gray appearance and higher stiffness are useful. Consider it for display-quality technical models, rigid housings and stiff brackets with a metallic-looking SLS finish. Alumide is polymer filled with aluminium particles, not a metal part. Its low elongation makes it a poor substitute for ductile nylon or structural aluminium alloy.
What should I validate before using EOS Alumide?
Avoid thin, notch-sensitive features and validate any electrical, grounding or thermal requirement; filler does not make a part a reliable conductor or metal heat sink. Is the requirement visual metallic appearance, stiffness, or actual metal performance? Would PA12-GF provide the needed stiffness with a different finish strategy?
How can EOS Alumide be finished?
The metallic gray is as printed. Blasting and clear coating may improve appearance, but confirm coating adhesion and any dimensional effect on a sample.
