Optomec, a specialist in metal additive manufacturing, has announced the launch of two new Directed Energy Deposition systems, the LENS CS 600 and CS 800 Controlled Atmosphere (CA). The new systems, which expand upon Optomec’s LENS series, were developed with the aim of maximizing the process’ build envelope while reducing the machine’s chamber volume and overall footprint.
The compact CS 600 and CS 800 are both based on Optomec’s Laser Engineered Net Shaping (LENS) technology, which itself uses a directed energy deposition process to build shapes from a bed of powdered metal, alloys, ceramics or composites using high-powered lasers. Because of the process’ ability to produce fully dense parts with excellent mechanical properties and fatigue resistance, the technology is well suited for a range of industrial applications, including part production and part repair.
Looking more closely at the new LENS systems, both the CS 600 and CS 800 are equipped with controlled atmosphere chambers, which enable the use of both non-reactive and reactive metals by keeping moisture and oxygen levels below 10 ppm. Both systems also integrate a Siemens 840D controller—providing smooth printing from three axis motion up to five axis motion—and are compatible with the latest generation LENS deposition head.
“These new systems come packed with next-generation DED components all born from signature Optomec know-how and built to provide affordable, high-quality metal additive manufacturing capabilities for industry’s most demanding requirements,” commented Tom Cobbs, Optomec LENS product manager. “The LENS CS 600 and CS 800 systems represent the latest in DED processing from precision deposition to cladding applications and extend our product portfolio to continue to provide high-value metal additive manufacturing solutions.”
Though both systems share a range of features, there are a few distinguishing elements that set them apart. For instance, the CS 600 has a smaller build capacity (600 x 400 x 400 mm) and is capable of laser powers up to 2 kW. The compact size of the CS 600 is suitable for small to mid-sized industrial applications, such as new part building, part repair, part modification and part coating. The CS 800 for its part boasts a larger build volume of 800 x 600 x 600 mm and laser powers of up to 3 kW.
Other shared features between the two machines include a linear three axis motion system (with an optional rotary table and/or tilt-rotate trunnion for four and five axis motions); closed loop process controls, thermal imaging, five axis tool path generation software, optional material starter recipes and access to Optomec’s customer service.
Optomec has reportedly already started fulfilling its first customer orders for the new LENS systems. The Albuquerque-based company also recently announced a partnership with Phillips Federal, the largest supplier of manufacturing equipment to the U.S. government, to resell its metal AM LENS systems to government agencies.
