Desktop Metal systems can rapidly churn out finished parts of steel, aluminum or many other alloys. The company's machines come in two sizes, a smaller one for use in confined spaces like a design studio, and a larger one for use in factories.
Desktop Metal's 3-D printers bind metal and ceramic powders into a soft polymer; then they extrude layers of this mixture to make an object, which is moved into a sintering furnace. The polymer burns off inside the furnace, and the metal fuses together without losing its shape. Ceramic layers keep metal parts from fusing wherever a designer wants pieces to stay separate.
