ED352 - course 'Handle and use pulsed lasers for additive manufacturing' - ALLONCLE / CONSTANTINESCU / CASANOVA

The LIFT laser technique (acronym standing for "Laser-Induced Forward Transfer") is an innovative printing technique taking advantage of the ability of pulsed lasers to transfer material pixels by applying a local pressure constraint with a high level of precision and controllability. During this training, the coaching team will present its scientific and technical operating principles and will illustrate its advantages through a demonstration of the manufacturing (and characterization) of a simple electronic device. The objectives are as follows:
· Acquire basic skills in the development and fine-tuning of a high-power laser manufacturing process.
· Understand the basic principles and potential of the LIFT digital laser printing process.
