The Alpha 140 combines innovative additive manufacturing technology with particularly simple operation at low system costs. The Alpha 140 thus offers an optimal solution for the tool-free production of metal parts, especially for small and medium-sized companies. Complex structures with the greatest geometric freedom can be mapped quickly and cost-effectively. Thanks to the open system, the customer can independently set the process parameters in the slicer according to his individual requirements. A wide range of usable metal materials is thus available through the free variation of process parameters.
The fiber-coupled diode laser with up to 200 W power processes stainless steel and alloys with ease. Due to the focus diameter of 110 µm, even the finest details and thin wall thicknesses can be precisely produced.
The small size of the machine with a footprint of 1.675 x 0.92 m saves space without sacrificing performance. The spindle-driven axis system with an installation space of 140 and 200 mm height enables high positioning and repeat accuracy of the laser system.
The materials that can be used for the Alpha 140 include stainless steels, tool steels and nickel-based alloys (e.g. IN625 and IN718). The components produced on the Alpha 140 achieve strengths comparable to conventional LPBF machines and have a component density of up to 99.9%.
With the aid of a laminar shielding gas flow, optimum process conditions are created for the inert welding process. At the same time, the laser optics are protected. Optionally, an integrated nitrogen generator ensures self-sufficient and efficient operation without additional external shielding gas supply.
The LMI SliceAM software, specially developed by LMI, offers intuitive data preparation through preset parameter sets, even without prior knowledge. The integration capability of Autodesk Fusion 360 and Autodesk Netfabb allows the complete workflow of a software.
Thanks to Kurtz Ersa's worldwide distribution network, the Alpha 140 is available in all demo centers and can also be delivered and made available globally within a very short time. 24/7 service included.
