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)
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
What is the difference between Metal-filled PLA and PLA?
Metal-filled PLA prints at 190-220°C nozzle / 50-60°C bed (No enclosure, moderate moisture sensitivity). PLA prints at 190-220°C nozzle / 50-60°C bed (No enclosure, moderate moisture sensitivity).
Is Metal-filled PLA or PLA stronger?
Our dataset does not include comparable tensile strength values for both. Qualitatively, Metal-filled PLA is suited to hefty, while PLA is suited to easiest to print.
Which prints at a higher temperature, Metal-filled PLA or PLA?
Both print at similar nozzle temperatures (190-220°C vs 190-220°C).
Is Metal-filled PLA or PLA better for beginners?
Both are similarly approachable: Metal-filled PLA (no enclosure, moderate moisture) and PLA (no enclosure, moderate moisture).
Should I use Metal-filled PLA or PLA for hefty?
For hefty, Metal-filled PLA is usually the better fit (Hefty). Choose PLA instead when easiest to print.
