Objectifs :
Laser-Induced Forward Transfer (LIFT) is an innovative printing technique that takes advantage of the ability of pulsed lasers to transfer small volumes of material (µm3) with a high level of precision and control. During this training course, the teaching team will introduce you to the scientific and technical principles of the process, demonstrating the manufacture (and characterization) of a simple electronic device.
The objectives of this training course are:
- Acquiring basic skills in using a high-power laser microfabrication work station.
- Understanding the basic principles of the process and potential of the digital laser printing.

Programme :
• 9h – 11h: lectures, Laser Induced Forward Transfer
▪ Technique description
▪ Key parameters (sample, printing, safety …)
▪ Pros and cons depending on the targeted application (electronics, bioprinting, others)
• 11h – 12h: hands on
▪ Presentation of the laser workstation.
▪ Safety rules for laser handling.
▪ Organisation of the afternoon training session.
• 12h – 14h: lunch break
• 14h – 17h30: hands on
▪ LIFT in liquid phase: samples preparation.
▪ Printing dots
-- demonstrating some key parameters
-- optical characterisations.
▪ Printing of a test vehicle
-- demonstrating some key parameters
-- optical characterisations.
▪ Printing lines
-- demonstrating key parameters
-- optical characterisations.
▪ Printing a simple electronic device
-- optical characterisations.
17h30 – 18h: debriefing, questions and final remarks

Pré-requis :
Basic knowledge (L3/BSc) of optics and physics

Equipe pédagogique :
P. Alloncle, C. Constantinescu

Méthode pédagogique :
7h (9h -12 h et 14h – 18h)
This one-day training course is organized in two sessions:
- a course focusing on the LIFT printing process and the key parameters for its optimization, its various possible fields of application, its advantages and disadvantages for industrial applications...
- a practical session on a laser printing workstation: i) how to use it, parameter settings, safety rules, ii) sample preparation, iii) printing a test vehicle and fabrication of a simple electronic microsystem, iv) optical diagnosis of samples.

Compétences acquises à l'issue de la formation :
- Know and understand how laser printing works.
- Identify its advantages and applications.
