Lasers in Manufacturing – LiM 2021

The LiM – Lasers in Manufacturing is the perfect platform for efficient knowledge transfer in the field of lasers and their applications.

The LiM 2021-Lasers in Manufacturing conference is organized by WLT e.V. (Wissenschaftliche Gesellschaft für Lasertechnik e.V. / German Scientific Laser Society).

The LiM focuses on the latest developments as well as future trends in the field of laser materials processing. The LiM consists of three sub-conferences – one for macro processing, one for micro processing, and one for Additive Manufacturing.

The conference topics address anyone who is interested in the potential of lasers in manufacturing in theory and application. It is the aim of the LiM to bring together international experts from research and industry in order to match scientific advances and economic needs for mutual benefit.

In cooperation with the Association of Industrial Laser Users (AILU), the European Laser Institute (ELI), the Japan Laser Processing Society (JLPS) and Swissphotonics.
