Additec has introduced a new desktop-size metal AM system called as μPrinter, advancing Directed Energy Deposition 3D printing. The new desktop machine capable of producing complex metallic components from both, wire and powder feedstock using Additec´s unique LMD-WP (Laser Metal Deposition-Wire Powder) Process. The ability to produce parts from wire feedstock makes operation and material handling very clean, as well as ensuring 100% material efficiency. Being also able to process powder closes the gap to conventional LMD and brings the ability to mix alloys on the fly. Switching between wire and powder is fast, does not require a nozzle change and can be done automatically on the same part. The Process works by having multiple high-power diode laser sources arranged around the central axis of the deposition head. Wire is fed through a central wire guide, while powder is fed through an annular gap nozzle around the wire guide.
Despite the compact outer dimensions, the print envelope is 120x160x450mm (XYZ) making the μPrinter useful beyond research applications. The build chamber is fully inert, and the small volume makes filling quick, affordable and safe. In addition to Additive manufacturing, it is also suitable for Cladding and Repair work on small components.
The μPrinter is based on Additec’s patented LMD-WP process, launched in 2016. Previously offered as a retrofit package that could be used to turn existing CNC platforms into metal 3D printers or hybrid manufacturing systems. In order to lower the barrier of entry, Additec now offers complete systems, starting with the μPrinter.
