3D Printing

Combined metal 3D printer and hybrid machining handles large builds

Optomec – a leading global supplier of production-grade additive manufacturing systems for 3D printed metals – launched its LENS 860 Hybrid Controlled Atmosphere (CA) metal 3D printer. The new addition to Optomec’s LENS Machine Tool Series has a larger build volume and supports higher laser power for affordable, high-quality metal hybrid manufacturing.

The LENS 860 Hybrid CA system has an 860 x 600 x 610mm work envelope, is equipped with a hermetically-sealed build chamber that maintains oxygen and moisture levels below 40 ppm for processing reactive metals, such as Titanium. The system can be configured with closed loop controls and a high-power 3kW fiber laser, making it ideal for building, repairing or coating mid to large size parts with superior metal quality.

The LENS 860 Hybrid CA system has an 860 x 600 x 610 mm (33.85 x 23.6 x 24 in.) work envelope and is equipped with a hermetically-sealed build chamber that maintains oxygen and moisture levels below 10 ppm for processing reactive metals, such as Titanium. The system can be configured with closed loop controls and a high-power 3kW fiber laser, enabling it to build, repair or coat mid to large size parts.

In addition to the LENS 860 Hybrid CA model, three more configurations are available. The LENS 860 Hybrid Open Atmosphere (OA) system is for processing non-reactive metals, such as Stainless Steel, Tool Steel Inconel, and so on. Two Additive-Only models (both Open and Controlled Atmosphere) round out the new large format Machine Tool Series of LENS systems.

All Machine Tool Series systems incorporate the LENS 3D Metal Printing technology, which has been enhanced for higher power and faster additive manufacturing. One key advantage of the LENS Hybrid configuration is the ability to use the milling capability to perform finish machining on a printed part without re-fixturing or aligning the component on a second machine. The LENS Machine Tool Series has a starting price of under $250,000.

“The new LENS 860 suite of systems builds on the success of our Machine Tool Series, first launched at IMTS in 2016. These new larger machines continue to demonstrate our ability to transition Optomec production-proven 3D Metal Printing capability onto traditional CNC platforms that match the cost, performance and ease-of-use demands of the traditional machine tool market,” said Mr. Dave Ramahi, Optomec president and CEO. “These products are a key element of our strategy to bring Metal Additive Manufacturing into the industrial mainstream.”

The LENS 860 Hybrid CA system can produce and repair larger parts cost effectively. It also offers versatility with the ability to print fine-features for thin wall structures and handle wide area cladding for wear coating applications. Optomec software enables 5-axis build strategies that combine additive and subtractive operations in a single tool path. A range of material starter recipes are available to help speed adoption with the LENS 860 Hybrid Controlled Atmosphere System.
First customer shipments will commence this year.
