Kurtz Ersa ALPHA 140

Alpha 140 – we are constantly evolving!

We have listened carefully to our customers – and in order to be able to offer an even more reliable product, we have developed our 3D metal printer accordingly. In addition to further technical developments, the printing and process quality has been optimized.

We have now been successfully marketing our Alpha 140 for two years. In order to live up to our claim of constantly developing further, it is a matter of course for Kurtz Ersa that we also continuously improve our products and adapt them to customer requirements. At Formnext 2022 in Frankfurt am Main in November, we were able to present technical enhancements in line with market feedback and our own accumulated experience, so that the Alpha 140 can manufacture additive components even more reliably in the future.


Some examples of our further developments:


  • The wear resistance through improved shielding against powder or process fumes was increased and the shielding gas supply was optimized.
  • These changes also resulted in an adaptation of the optics holder, which has the positive side effect of further stabilizing the optics and achieving an even better print result.
  • The Alpha 140 can now reach web speeds of up to 500 mm/s and thus travel 2.5 times faster than before.

In addition to the technical enhancements of the basic Alpha 140, the integrated nitrogen generator and powder extraction options have also been further improved in this train. The integrated nitrogen generator makes it possible to integrate the additive manufacturing system even without an existing nitrogen infrastructure – simply connect to the existing compressed air supply and the Alpha 140 is “ready to print”. And the integrated powder extraction makes it even more convenient, and therefore safer, for the operator to de-powder the components directly in the Alpha 140 after the printing process. These two options make the Alpha 140 a compact all-in-one solution, perfect for entry-level additive manufacturing.


The further developments presented in Frankfurt are now undergoing a final long-term test at our Development and Technology Center (ETC), so that the series will be released at the end of Q1/2023.
