Composite-filled filament combines a base polymer with fibers, minerals, metal or other particles. It changes stiffness, density, abrasion, surface and flow. The filler must match the function.
Common fillers
- Carbon/glass for stiffness.
- Metal for weight and heat.
- Mineral for surface or density.
- Wood for appearance.
Process effects
Abrasion, clogging and brittleness can increase. Use a suitable nozzle, dry the material and calibrate flow and retraction.
Selection
- Required property.
- Nozzle.
- Orientation.
- Surface.
| Filler | Benefit | Trade-off |
|---|---|---|
| Carbon | Stiffness | Wear |
| Glass | Stiffness | Wear |
| Metal | Weight/effect | Abrasion |
| Mineral | Finish | Flow |
Common engineering mistakes
- Using a brass nozzle.
- Expecting all properties to improve.
- Ignoring orientation.
- Not drying.
- Keeping the old profile.
Buyer checklist
- What property is needed?
- Is the filler abrasive?
- Nozzle suitable?
- Material dry?
- Flow calibrated?
