Metal-filled PLA vs PETG
Compare Metal-filled PLA and PETG 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)
PETG
APolyethylene Terephthalate Glycol-modified
Tougher than PLA, higher temp tolerance, more durable in real-world use

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
Frequently Asked Questions
Is Metal-filled PLA or PETG better for 3D printing?
PETG 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 PETG is best for Tougher than PLA, higher temp tolerance, more durable in real-world use.
What are the temperature differences between Metal-filled PLA and PETG?
Metal-filled PLA prints at 190-220°C nozzle / 50-60°C bed. PETG prints at 215-270°C nozzle / 70-90°C bed.
Do Metal-filled PLA and PETG need an enclosure?
Metal-filled PLA: not needed. PETG: optional.
Which is more beginner-friendly: Metal-filled PLA or PETG?
Both Metal-filled PLA and PETG are beginner-friendly options.
