M2 Direct from CAD to Metal- Additive Manufacturing

What is Additive Manufacturing?

 

The M2 cusing is the workhorse of the Concept Laser system fleet and has been designed with ultimate flexibility in mind. Whether your application is serial production of parts or reactive materials R&D, the M2 delivers the necessary capabilities without compromise. The available laser options (200 or 400W, single or dual) allow our customers to tailor the system for their specific needs. A closed-loop material handling system ensures that the operator’s contact with unmelted reactive powders and soot is reduced to the absolute minimum. This, along with the patented filter-change mechanism with water-flood passivation, are part of the design that makes the M2 unrivaled in terms of safety. The optional integrated QM modules provide the user with absolute confidence that the build has proceeded as expected, which is especially important in the serial production of critical components.

The way it works

The machine takes metal powder and uses a high-energy laser to melt it in a designed pattern. The laser will layer the melted dust to fuse whatever part are need from the ground up, creating intricate designs. The process produces parts with complex geometries and precise mechanical properties from a three-dimensional computer-aided design.

This method allows parts that once had to be built in simple sub-stages and then stuck together to be made in one go, which eliminates many fabrication problems and can reduce costs by as much as half. It also improves safety because metal powders like titanium burn in air, so the M2 is designed to fabricate the parts in a neutral atmosphere without supervision.

User Experience

This process significantly reduces the manufacturing time required to produce parts from months to weeks or even days in some cases,” said Andy Hardin, the integration hardware lead for the Engines Office in SLS. “It’s a significant improvement in affordability, saving both time and money. Also, since we’re not welding parts together, the parts are structurally stronger and more reliable, which creates an overall safer vehicle.”

Technical Data:

The M2 cusing is designed in line with ATEX guidelines and thus makes it possible to process aluminium and titanium alloys safely. The machine is robust and suitable for 3-shift operation.
The complete process, from processing of the construction job through to removal of the component and powder conditioning, all takes place under the exclusion of oxygen. This therefore prevents the reactive materials from being contaminated with oxygen.
