Copperfill filament.
Experimental filament.
For experienced user.

Testing showed reliable results using the all metal hot-ends, such as the E3D and the Makerbot Replicator 2 hotend. Hotends which use a teflon isolator coupler can generate adhesion to the copper filament possibly leading to clogs and is there for not recommended for novice users yet. 


  • Copper shine when polished
  • 3 times heavier than standard PLA

Heat will travel through Copperfill filament more efficiently, because of the metal particles. This results in two things; it will heat up easier in your hot-end and it will cool down faster when leaving the nozzle.
1- The fact that the filament heats up easier in the nozzle usually means for most printers to print at lower temperatures and keep the filament moving through the nozzle by printing at relatively high speeds.
2- The better cool down properties when leaving the nozzle means good performance on overhanging parts, this is a big plus for printing busts that often feature overhanging parts such as the chin, nose and ears.

Use coarse steel wool to polish the surface of the print. You can apply quite a bit of pressure but don’t polish a specific spot for too long, it’ll get hot and softens the material.
The print should now look already quite shiny and exposed surfaces should be looking shimmer and be smooth without visible print lines. Next we apply a thin coat of black spray paint and immediately use a white cloth to wipe it off. Places hard to reach will stay slightly tainted black which enhances the contrast.
Last step is using a copper polish which helps get to get the extra shine you would expect from a metal and also helps creating an interesting patina over time.

Due to all the different types of hot-end it's extremely difficult to give a temperature advice. Please consider these tips, provided by the manufacturer, as a starting point to find the temperatures that work well in your setup. You may have to adjust the temperature settings slightly based on your type of printer.
