iMakr's Verdict
Filamet™ Copper PLA is the closest you can get to printing in metal from a FDM printer. It prints just like PLA, with a reduced speed to allow enough energy to melt the dense filament. Printed parts look, smell and feel like copper, even when they are not kiln fired.

Key features

  • High metal content: With 90% copper by weight printed parts feel, weigh and smell exactly like real metal parts.
  • Multiple post processing possibilities: Printed parts can be sanded, polished, coated, kiln fired or allowed to oxidise for a range of finishes.
  • Easy to print: Filamet™ prints like regular PLA, just reduce speed to around 50%.

Printing Tips
  • Print at 50% of your usual printing speed to allow the filament to melt properly.
  • Use an all metal hot end, the metal particles are abrasive and will damage other hot ends, and will wear all hot ends over time.
  • The filament is brittle and may snap during printing. Mounting the filament externally from the printer, ideally above with a clear path to the extruder, will reduce the likelyhood of breakage during printing.
  • A Magic Black Powder is available to purchase separately to kiln fire printed parts.
  • The sintering process can be downloaded below.
  • Magic Black Powder mixing ratio is about 1 cup of water to 2 cups Magic Black Powder.
