Metal-filled PLA vs PETG
Compare Metal-filled PLA and PETG filaments side-by-side so you can pick the right one for your 3D printing project.
Metal-filled PLA vs PETG: Metal-filled PLA is known for hefty, while PETG is known for tougher than pla. Metal-filled PLA is easier to print; PETG prints at higher nozzle temperatures (230-250°C vs 190-220°C). Choose Metal-filled PLA for hefty, or PETG for tougher than pla.
Key differences at a glance
Metal-filled PLA
FPLA + metal shavings
Hefty, can show metal-like properties (patina/polish/magnetism)
PETG
APolyethylene Terephthalate Glycol-modified
Tougher than PLA, higher temp tolerance, more durable in real-world use
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)
PETG Strengths
- Tougher than PLA, higher temp tolerance, more durable in real-world use
- Good clarity and low friction among easy-to-print materials
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
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
