Controlled-Atmosphere DED Systems


LENS CS 600 and CS 800 Controlled Atmosphere (CA) DED Systems offer up new additions to the Laser Engineered Net Shaping (LENS) Classic System Series. The printer’s controlled atmosphere chambers allow for processing of both non-reactive and reactive metals in an atmosphere that keeps moisture and oxygen levels at less than 10 ppm. A powerful Siemens 840D controller allows for smooth and sophisticated 3D printing from three-axis up to simultaneous five-axis motion. These systems are also compatible with Optomec’s latest generation LENS deposition head providing higher power laser processing (up to 3 kW), interchangeable print nozzles, and variable spot sizes.


Optomec LENS systems use an additive manufacturing technique called directed energy deposition (DED), where high-powered lasers build structures layer by layer directly from powdered metals, alloys, ceramics or composites to produce fully-dense parts with excellent mechanical and fatigue properties.


The LENS CS 600 and CS 800 systems are designed to maximize the LENS process build envelope while minimizing chamber volume and system footprint. The base LENS machines are equipped with a linear three-axis motion system, but optionally can be delivered with a user interchangeable rotary table and/or tilt-rotate trunnion for four and five-axis operations. The Siemens motion controller provides an easy-to-use push button HMI and utilizes industry standard G&M codes to drive the system. Optional material starter recipes, closed-loop process controls, thermal imaging, five-axis tool path generation software, and unparalleled customer service round out the systems.


All classic series systems incorporate Optomec industry-leading LENS 3D Metal Printing technology, which has been enhanced for higher power and faster additive manufacturing. One unique advantage of LENS is that it is able to add metal to existing parts for repair and coating applications that extend the useful life of components without the need to re-fixture or align the component on a second machine.
