Technology Overview

This additive method of manufacturing is gaining traction in the industrial marketplace for the speed, complexity and efficiencies it brings to the shop floor.

3D printing is a manufacturing process that build layers to create a three-dimensional solid object from a digital model. 3D printing can produce parts with geometric features that cannot be accomplished by other manufacturing processes.

ExOne builds functional 3D objects from the bottom up, one layer at a time with durable, industrial-strength materials. ExOne® 3D printing systems selectively bind thin, cross-sectional layers of fine powder. As the printhead passes over the powder bed, binder is deposited into the powder. The powder bed lowers and is coated with another layer of the print powder. With each successive pass of the printhead, more of the object is bound until a near-net shape object is completed.

For metal-based printing systems, the printed volume is typically the part itself. For sand systems, the printed volume forms a mold package for use with metal casting techniques.
