Electromagnetic print nozzle for direct-write additive manufacturing with resistive renditions

Title: Electromagnetic print nozzle for direct-write additive manufacturing with resistive renditions

Abstract

A method and apparatus for additive manufacturing that includes a material guide for directing a supply of working material. An advancement mechanism comprising one or more pistons, pushers, plungers and/or pressure regulation systems are positioned behind at least a portion of the supply of working material for advancing the working material forward. The working material is heated using an electro-magnetic heating element and the melted or molten working material is deposited from a tip positioned at an end of the material guide.
