Flying Ray

3D multi-head printing - from prototype to series production.

The demand for metallic 3D printing is continuously increasing. Especially in terms of geometry freedom, customizability and use for small series. However, the production of large parts and series components is also being targeted by the industry. With the Flying Ray, Kurtz Ersa is taking a significant step in this direction. We are successively developing our large-format printer further and realizing large-part and series production.

Highly functional due to vertically impinging laser beams

The Flying Ray presents itself with a multi-axis system for lasers. It is highly innovative due to its vertically impinging laser beams. In the basic version, eight lasers are used simultaneously on eight swivel arms. The highlight: They work in parallel in overlapping work areas. The laser power is adaptive. Axes and lasers are modularly expandable.

Optimal results with build processor and slicer

Metallic 3D printing is not a trivial matter. It requires knowledge of machine parameters, processes and materials. To connect software and hardware, you need a user interface that reliably handles communication. The uncomplicated integration of your 3D models is important to us. By means of the slicer specially developed by Kurtz Ersa, data preparation becomes child´s play. Likewise, we ensure easy operation through an intuitive human-machine interface.



  • Eight fiber lasers in the standard configuration (expandable)
  • Continuous 90° impact angle of lasers
  • Highly innovative swing arm concept instead of Galvano scanners
  • High positioning accuracy
  • 45° swivel range for large overlap
