Metal infused PLA filament. What ideas come to mind when you have the ability to 3D desktop print with metal-like filaments? Please note these are metal filaments made from PLA, which is not a high strength material, but a material that gives you the look, weight and feel of metal, perfect for modelling and visual prototyping. This is a very easy to print material on the majority of 3D desktop printers. Due to the abrasive nature of this filament, your 3D Printer needs to be fitted with a hardened steel or Teflon coated nozzle.
