Alpha 140

Your entry into metallic 3D printing.

Kurtz Ersa Alpha 140 - plug'n produce with best price-performance ratio

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.

Perfect match - LMI and Kurtz Ersa

The cooperation between Laser Melting Innovations GmbH & Co. KG (LMI), based in Aachen, and Kurtz Ersa is taking metallic 3D laser printing further. Together, they offer a cost-effective entry point for medium-sized businesses that benefit from the highest quality and very fast availability. At the same time, the Alpha 140 remains adaptable and can be tailored to customer needs.
