Copper-fill PLA

Intermediate

Copper Powder-Infused Polylactic Acid

A PLA composite loaded with fine copper powder that gives prints real metallic weight and the ability to develop a genuine patina over time. Copper-fill PLA is significantly heavier than standard PLA and can be polished, brushed, or chemically aged to achieve a true copper finish indistinguishable from cast metal at a glance.

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

Printing Tips

  • Use a hardened steel nozzle with a 0.5 mm+ bore — copper particles clog 0.4 mm brass nozzles quickly.
  • Print slowly (20-40 mm/s) to avoid under-extrusion; the heavy copper powder increases backpressure in the hotend.
  • Sand with 400-800 grit paper and buff with a cotton cloth to reveal the metallic copper surface beneath the PLA matrix.
  • Apply liver of sulfur solution to create an authentic green verdigris patina on finished prints.
  • Increase flow rate by 5-10% to compensate for the higher-density material; standard flow often leaves gaps.
  • Store sealed with desiccant — moisture causes the copper particles to oxidize inside the filament, weakening layer bonds.
