Dutch Researchers Develop Technique to Laser 3D-Print Metal Drop-by-Drop

Published by , November 2, 2018 1:44 pm

(3Ders.org) University of Twente researchers have developed a new metal 3D printing technique which allows a laser apparatus to print metal structures drop by drop, including in pure gold, on the few micron scale. The new technique, which has been called laser-induced forward transfer (aka ‘LIFT’), uses an ultra-short laser pulse to melt tiny bits of metal from a nano-thickness film. The ability to create fully free-standing and overhanging structures is crucial for printing complex 3D devices. Using LIFT in combination with chemical etching displays one possibility for creating these types of structures on a small scale.
