Concept Laser M Line

The design of the M Line allows for time & cost savings and the ability to manufacture high-quality production parts at scale.

Economical serial production

The M Line is more than just a single machine. It’s designed specifically for additive production, and was developed around the need for quality, safety, and productivity. The differentiator is the modular machine design, which allows for economical series production, at scale.

The modular machine technology concept physically decouples the Laser Processing System (LPS) and the Material Handling Station (MHS) units used for upstream and downstream stages of the production process and part production.

These tasks can now be carried out in parallel and physically separate from one another saving you time and cost.

Success for the EROFIO group

In less than three months after receiving and installing an M Line system the team at EROFIO successfully 3D-printed its first Mold Core. The Core contains more than eight independent, internal conformal cooling channels, stretching over eight meters in length and between five to eight-millimeters in diameter. The improved cooling will increase the overall plastic injection process productivity through decreased cooling cycle time and warpage, and the improvement of the injected plastic part aesthetics.

When compared with conventional manufacturing processes, additively manufacturing this part has reduced finishing requirements by 90% and reduced the total manufacturing time, from powder to mold assembly, by 30%.

Following remote optimization support from the GE Additive team in Lichtenfels, the part was successfully printed on its first attempt, over a six-day period.

Material Handling Station (MHS)

The handling of material is based on an integrated powder cycle in the MHS under inert gas atmosphere (nitrogen or argon). It is combined with the concept of separated modules and an automated lid system to allow contactless and inerted powder handling during operation. The protective atmosphere also avoids aging of powder material caused by oxygen ingress and humidity. After a build job is complete, the lidded build and overflow modules are moved into the inerted MHS. The operator can remove powder from both modules with the suction lance. The used powder can be recovered and reprocessed by the integrated sieving station of the MHS and loaded into a new powder module if desired.
