Abstract
Provided are a systems and methods for manufacturing objects by solid freeform fabrication, especially titanium and titanium alloy objects, wherein the deposition rate is increased by using two separate heat sources, one heat source for heating the deposition area on the base material and one heat source for heating and melting a metallic material, such as a metal wire or a powdered metallic material.
Claims1
A system for building metallic objects by solid freeform fabrication, comprising:
- a first welding gun for pre-heating a portion of a surface of a base material;
- a second welding gun for melting a source of metal into droplets of metallic material that are deposited onto the preheated surface of the base material;
- and
- a computer model of an object to be formed to define a deposition profile welding gun such that the object is built by fusing successive deposits of the metallic material onto the base material.
