3D Print Gold Microstructures Using LIFT

Posted on Updated on

According to the UT researchers Matthias Feinaeugle, Ralph Pohl, Ton Bor, Tom Vaneker and Gert-willem Römer, “laser-induced forward transfer (LIFT), they are able to build, drop by drop, a structure with copper and gold microdroplets. The copper acts as a mechanical support for the gold. In their paper in Additive Manufacturing the researchers show, for example, a printed helix: this could act as a mechanical spring or an electric inductor at the same time. This helix is printed with copper around it: together with the helix, a copper ‘box’ is printed”.
