Metal-filled PLA vs ASA
Compare Metal-filled PLA and ASA filaments side-by-side so you can pick the right one 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

Green marks the generally easier or more forgiving option in that row, based on tier, enclosure needs, and moisture sensitivity. It is not always the better choice for a specific job, so weigh it against what your project actually needs.
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.
