Company Profile (Optomec)

Optomec is evolving the world of additive manufacturing by enabling new dimensions in 3D printing. The LENS and Aerosol Jet families of printers support a range of materials for metals, electronics and other applications, and are able to implement feature sizes never before possible. And, our open system architecture means they can be easily integrated into existing production environments for a non-disruptive hybrid approach that combines with traditional manufacturing systems. With Optomec, the promise of high-volume additive manufacturing is a reality today, transforming how companies design, build and maintain critical parts and products.
