Metal-fill PLA

Intermediate

Metal Particle Composite PLA

PLA infused with real metal particles (copper, bronze, or steel) that gives prints an authentic metallic weight and finish. Parts can be polished to a real metal sheen and develop natural patina over time. Significantly heavier than standard PLA.

Nozzle Temp195–220°C
Bed Temp50–60°C
Print Speed20–40 mm/s

Printing Tips

  • Use a hardened steel nozzle — metal particles wear through brass nozzles in 1-2 prints.
  • Print SLOWLY (20-30 mm/s). Metal-fill filament is abrasive and clogs easily at higher speeds.
  • Polish prints with 400-800 grit wet sandpaper, then apply metal polish (Brasso works well) for a real metal look.
  • Parts are 2-3x heavier than standard PLA — adjust infill accordingly and reinforce overhangs.
  • Apply liver of sulfur solution to copper-fill prints for an authentic aged patina effect.
