Subject description

Short description:

The subject covers the field of additive manufacturing (AM) with emphasis on AM of metals. By lectures, tutorials and hands-on work in the lab students acquire the knowledge and skills required to perform the whole AM production chain including product design process selection, , manufacturing process and its control, as well as post processing. In-depth knowledge of metal AM manufacturing is enriched by practical lab work on different AM processes including wire-arc, selective laser melting and direct laser metal deposition AM systems.


  •  Physics (radiation, wave, electron beam, laser, heat conduction, advection and convection, plasma, ultrasound, x-ray),
  •  Materials (properties of metals)
  •  Laser systems (laser sources, laser light absorption, laser beam parameters, optical elements such as fiber leads, collimator, focusing optics)
  • Manufacturing technologies 1 and 2 (characteristics of joining processes and material removal processes )
