Technologies and equipment used
DED (Directed Energy Deposition) – metal printing
Directed energy deposition is a technological process in which the fed material is melted directly at the desired location using a laser beam.

InssTek MX600 - DED technology
The InssTek printer uses the so-called Powder-based DED method, where powder is injected into the laser-exposed area and is carried away by an inert gas.
Parameters
- 2kW fiber laser
- 5-axis movement
- Working press 450x600x350mm
- SDM800 (beam diameter 800 µm, layer height 250 µm)
- SDM1600 (1600 µm beam diameter, 600 µm layer height)
- SDM2400 (beam diameter 2400 µm, layer height 900 µm)
- Up to 4 materials at a time
- 3-axis printing capability with preheating to 500°C with 150x150x150mm part size
InssTek MX-LAB – DED technology
Parameters
- 0.5kW fiber IR laser

LPBF (Laser Powder Bed Fusion) – metal printing
An even layer of powder is applied to the vertically adjustable table and then the area corresponding to the cross-section of the desired piece is melted by a laser beam. Gradual application of individual cuts achieves the desired shape.
