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.
