Metal Printing

·  Compatible with complex geometries for cooling, heating, porting, venting, nested cores, spiral vents and volute shapes, as well as the integration of multiple components

·  Lattice structures allow for reduced material cost while maintaining strength and keeping parts lightweight

·  Economical short-run production of small metal components

·  Great for sand molds and cores

·  Cost effective

·  Faster alternative to traditional methods

·  Metal castings used for industrial, military and consumer products
