Finishing Degrees

The right finish and color can transform a print into a product. With Metal 3D Printing, the possibilities range from basic supports removal and a matte finish to electropolishing for a reflective surface, or post-machining for accuracy requirements.

How Does Metal 3D Printing Work?

Metal 3D Printing is a laser-based technology that uses powdered metals. Similar to Laser Sintering, a high-powered laser selectively binds together particles on the powder bed while the machine distributes even layers of metallic powder. Support structures are automatically generated and built simultaneously in the same material, and are later manually removed. Once complete, the part undergoes heat treatment.
