Kai Parthy has just announced his latest 3D printer filament creation, MOLDLAY. This new material is wax-like and enables its users to 3D print an item that they would like to cast. The full details on how to use the filament to make your own mold for casting tin or brass can be found here: http://3dprint.com/40579/moldlay-kai-parthy/ Below are some of the material's features/specs:

  • Near zero warping
  • Can be printed without a heated bed
  • Prints at temperatures of 170 – 180° C
  • Molds must be treated at 270°C in an oven
