Metal-filled PLA vs PLA
Compare Metal-filled PLA and PLA 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)
PLA
APolylactic Acid
Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal

Strengths Comparison
Metal-filled PLA Strengths
- Hefty, can show metal-like properties (patina/polish/magnetism)
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
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
PLA Caveats
- Creeps under sustained load
- Poor heat resistance, UV degradation, can shatter on drops
- Not great for sanding/gluing/painting/touch-ups
Frequently Asked Questions
Is Metal-filled PLA or PLA better for 3D printing?
PLA 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 PLA is best for Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal.
What are the temperature differences between Metal-filled PLA and PLA?
Metal-filled PLA prints at 190-220°C nozzle / 50-60°C bed. PLA prints at 185-235°C nozzle / 50-60°C bed.
Do Metal-filled PLA and PLA need an enclosure?
Metal-filled PLA: not needed. PLA: not needed.
Which is more beginner-friendly: Metal-filled PLA or PLA?
Both Metal-filled PLA and PLA are beginner-friendly options.
