Make metal parts with 3D printer using lost polymer casting method

A former Electrical and Explosives Engineering student named Peter, going by the handle ‘lyratron’, has shared a handy method for making metal parts using a standard plastic-printing 3D printer. After learning a technique called lost wax casting whilst studying at New Mexico Tech, Peter decided that carving machinable wax with a CNC milling machine was too much effort. He therefore began experimenting with lost polymer casting: a similar process, […]
