Printing inks with CW lasers

Treballs Finals de Grau de Física, Facultat de Física, Universitat de Barcelona, Curs: 2019, Tutor: Juan Marcos Fernández PradasLaser-induced forward transfer (LIFT) printing is a technique with a great future as an alternative to the inkjet printing since it is not limited by the viscosity and size of the printing particles as inkjet. Even so, the use of expensive pulsed lasers could hamper its development. The use of continuous lasers can be an alternative since they are used industrially, and their cost is lower. In this work, different continuous LIFT printing conditions are studied by changing the thickness of the donor layer, the scanning speed and the laser power. A minimum of 0.5 Ω/sq is obtained and optimal printing conditions are determined for the 3 studied parameter
