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 vs ASA: Metal-filled PLA is known for hefty, while ASA is known for excellent uv resistance (outdoors indefinitely). Metal-filled PLA is easier to print; ASA prints at higher nozzle temperatures (220-275°C vs 190-220°C). Choose Metal-filled PLA for hefty, or ASA for excellent uv resistance (outdoors indefinitely).
Key differences at a glance
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
Detailed Comparison
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
