Print in Steel!

3d printing with metal on your own desktop 3d printer! This amazing one of a kind filament will allow you to print with actual steel at home! Straight from the printer parts look almost laser sintered with a matte finish. With a bit of sanding and polishing the copper particles will start to shine and shimmer unlike any 3d printing filament you have seen before. The weight of the material is about 3 times heavier then our regular PLA/PHA. *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.

Build Platform

  • Colorfabb PLA/PHA performs well on both heated and unheated build paltforms. For those users printing on a cold build paltform we suggest applying masking tape to the build area. The rough surface of the tape will provide enough adhesion for the first layer to stick and print almost without any warping.
  • Users with a heated build paltform have quite a few options. Most commonly glass or aluminium. For printing directly onto glass or aluminium we suggest the application of a glue stick. A very thin layer will be sufficient to keep your print nicely in place.
  • Another option is the use of materials such as Buildtak.

Gayest filament of all time

Product: ColorFabb SteelFill

The steel fill is the gayest filament of all time. You could pattycake beach sand into a shape and it would be stronger than this rubbish. I still have 90% of the roll left if anybody wants it free.

SteelFill Electronic Ferrites!

Product: ColorFabb SteelFill

Quality as expected from ColorFabb. Composites can sometimes be tricky to get right. SteelFill works great. Using it for custom low level ferrite shapes. It actually works.
