Printing Functional 3D Microdevices by Laser‐Induced Forward Transfer

Slender, out‐of‐plane metal microdevices are made in a new spatial domain, by using laser‐induced forward transfer (LIFT) of metals. Here, a thermocouple with a thickness of 10 µm and a height of 250 µm, consisting of platinum and gold pillars is demonstrated. Multimaterial LIFT enables manufacturin...

Summary:Slender, out‐of‐plane metal microdevices are made in a new spatial domain, by using laser‐induced forward transfer (LIFT) of metals. Here, a thermocouple with a thickness of 10 µm and a height of 250 µm, consisting of platinum and gold pillars is demonstrated. Multimaterial LIFT enables manufacturing in the micrometer to millimeter range, i.e., between lithography and other 3D printing technologies.
