Metal Printing

Metal printing is the most cost-effective technology for 3D printing metal parts. It produces durable parts that are lightweight and economical for short-run production. Unlike DMLS printing, however, metal printing is only compatible with stainless steel bronze alloy.

Metal printing is excellent for creating sand molds and cores. Like all 3D printed metals, it is able to produce complex geometries, such as spiral vents and nested cores, that would be impossible to produce with traditional manufacturing technologies like CNC machining. Because it has no lead times or tooling costs, it is faster and less expensive than other technologies for small batches.

For medium- to large-sized productions, however, CNC machining is often a more cost-effective alternative. Machining scales well at volume and offers excellent fine detail, surface finish and material options.
