Research group of Laser Processing – LUT Laser

The research group of Laser Processing at LUT Mechanical Engineering, known internationally as LUT Laser, focuses on researching and developing energy-efficient manufacturing methods and processes based on the use of a laser beam for industrial needs.

In addition to manufacturing methods, the research also targets other methods that utilise laser beams. Laser processing is a generic term for methods in which a laser beam is used to manufacture a range of products from various materials.

In general, laser processes are efficient methods that comply with sustainable development and that are used for several tasks, such as joining, cutting and drilling metals and non-metals.

With laser processing, production lead-through times can be shortened, product designing and quality can be improved, and completely new types of products and production technologies can be developed.

The focus areas of the laboratory research include the traditional welding, surface treatment and cutting of metallic materials and the processing of non-metallic materials. The newest focus area is research on additive manufacturing methods, the so-called 3D printing or sintering.

The laboratory's hardware enables versatile research and development work for laser processing.
