GE Additive, the AM division of General Electric, has announced an update to its Concept Laser M2 cusing and M2 cusing Multilaser machines. The new versions reportedly improve productivity and print reliability and can contribute to lower overall operating costs. The upgraded metal AM systems are now available to order.
Since GE’s acquisition of German metal AM company Concept Laser in 2016, the M2 cusing family of printers has played a critical role in GE Additive’s product portfolio. Based on a Direct Metal Laser Melting (DMLM) technology, the M2 cusing printers have found applications across a wide range of industries, including aerospace, automotive, medical and dental.
With a slew of new features and upgrades to the metal AM systems, GE Additive is aiming to improve its clients’ overall productivity and manufacturing costs.
“Customers, especially in the aerospace and medical industry, have high expectations. For that reason we continuously review our solutions portfolio to confirm we are offering the right machines and the right materials for an ever-demanding range of applications,” said Meddah Hadjar, General Manager, Additive Laser Products at GE Additive.
Notable upgrades to the M2 cusing family include a new gas flow system, a new cooling unit for optical components, a higher build chamber and a more tightly controlled build environment.
The new gas flow system, which is backed by redundant oxygen monitoring and a closed inert gas circuit, promotes higher part quality and reliability thanks to a better flow in the build chamber. By ensuring higher part quality, GE Additive says the new gas flow system can also help to lower operating costs.
A new cooling unit for optical components integrates a temperature controlled environment which is monitored by a range of new sensors to prevent influence from both external and internal temperature changes. By establishing tighter controls of the build environment, the M2 cusing family promises better print quality and reliability for metal parts.
The upgrades also include a higher build chamber (with a z-axis of 350 mm) for printing taller parts, giving the new machines an overall build volume of 250 x 250 x 350 mm. In combination with a “newly designed heating” system and advanced closed-loop control, the upgraded M2 cusing printers ensure higher precision and accuracy along the z-axis.
Finally, the newly released metal AM systems also come with updated software and additional sensors for data analytics.
Recently, GE Additive also introduced the Arcam EBM Spectra H metal AM system—the first product to be put out by Sweden-based Arcam since its acquisition by GE in 2016. Based on electron beam melting (EBM) technology, the new Spectra H delivers up to 50% faster build speeds than competing EBM systems.
