Metal-filled PLA vs ASA
Compare Metal-filled PLA and ASA filaments side-by-side. See which one is best for your 3D printing project.
Metal-filled PLA
FPLA + metal shavings
Hefty, can show metal-like properties (patina/polish/magnetism)
ASA
AAcrylonitrile Styrene Acrylate
Excellent UV resistance (outdoors indefinitely), tough, matte surface

Strengths Comparison
Metal-filled PLA Strengths
- Hefty, can show metal-like properties (patina/polish/magnetism)
ASA Strengths
- Excellent UV resistance (outdoors indefinitely), tough, matte surface
- Less warping than ABS; low viscosity enables very high speed printing
- High heat tolerance (~boiling water range)
Considerations
Metal-filled PLA Caveats
- Weaker than regular PLA
- Very brittle on/off spool
- Very expensive and higher density means fewer prints per spool
- Usually better replaced by paint/inserts/electroplating
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
Frequently Asked Questions
Is Metal-filled PLA or ASA better for 3D printing?
ASA is generally rated higher (Tier A) compared to Metal-filled PLA (Tier F). However, the best choice depends on your specific needs: Metal-filled PLA is best for Hefty, can show metal-like properties (patina/polish/magnetism), while ASA is best for Excellent UV resistance (outdoors indefinitely), tough, matte surface.
What are the temperature differences between Metal-filled PLA and ASA?
Metal-filled PLA prints at 190-220°C nozzle / 50-60°C bed. ASA prints at 220-275°C nozzle / 90-110°C bed.
Do Metal-filled PLA and ASA need an enclosure?
Metal-filled PLA: not needed. ASA: recommended.
Which is more beginner-friendly: Metal-filled PLA or ASA?
Metal-filled PLA is more beginner-friendly as it doesn't require an enclosure.
