Title: Additive manufacturing via direct writing of pure metal and eutectics through latent heat position control

Abstract

An additive manufacturing system for producing metal parts from pure metal or eutectic alloys. The system includes an additive manufacturing print head, a print head heater system, an agitation system, a nozzle in the additive manufacturing print head, a reservoir for melting the metal, and a long heated tube for conditioning the alloy for extrusion in the semi-solid state through a nozzle.
