The Alpha 140

The Alpha 140 combines innovative additive manufacturing technology with simple operation at low system costs. The Alpha 140 offers an optimal solution for the tool-free production of metal parts, especially for small and medium-sized companies.

The Alpha 140

Performance and precision

A fiber-coupled diode laser with 140 W power offers optimal properties for processing stainless steel, nickel alloys and tool steel alloys. The focus diameter of 140 µm enables the production of fine details and thin wall thicknesses. Layer thicknesses between 30 µm and 90 µm and the open process parameters allow a production process optimized depending on the component and material.

Soon available: The Alpha 140 for processing of Aluminium alloys!

Build space and footprint

The Alpha 140 offers a round build space with 140 mm diameter and 200 mm height. A spindle-driven axis system enables high positioning and repeat accuracy of the laser system. The system size of the machine with a footprint of 1,70 m x 0,95 m allows space-efficient use in production environments and research laboratories.

Process materials

The components produced on the Alpha 140 achieve strengths comparable to those of conventional LPBF machines and densities of up to 99.9%. Available materials and parameter sets for the Alpha 140 include stainless steels, tool steels and nickel-based alloys (e.g. IN625 und IN718). The open system design enables in-house material qualification and material development. A further developed Alpha 140 for processing aluminum alloys and will be available shortly. enables the processing of aluminum alloys will be available shortly.

Process stabilizing inert gas flow

The laser optics, which is guided coaxially to the powder bed, enables a constant focus diameter in the entire build space. A laminar inert gas flow creates optimal process conditions for the inert welding process and for the protection of the laser optics.

A nitrogen generator that can be optionally integrated into the machine housing enables an autonomous operation without additional external inert gas supply and reduces the process costs.

 

Integrated solution

With LMI SliceAM, we offer our own software for data preparation: Perfectly adapted to user and machine. Preset parameter sets for data preparation without previous knowledge. The software offers the possibility to influence process parameters extensively and a simple generation of support structures.

The integration of the Alpha 140 in Autodesk Fusion 360 and Autodesk Netfabb enables the complete additive manufacturing workflow in one software package. From component design and simulation to the generation of support structures and data preparation for the Alpha 140, more information on the integration in Fusion 360 can be found here.
