New laser-induced forward transfer (LIFT) technology fabricates slender, out-of-plane metal microdevices. This method successfully created a 10 µm thick, 250 µm tall platinum and gold pillar thermocouple.

Area of Science:

  • Materials Science
  • Microfabrication
  • Additive Manufacturing

Background:

  • Conventional microfabrication techniques have limitations in creating complex 3D microstructures.
  • There is a need for advanced methods to produce microscale devices with out-of-plane features.

Purpose of the Study:

  • To demonstrate a novel application of laser-induced forward transfer (LIFT) for fabricating metal microdevices.
  • To showcase the capability of LIFT in creating slender, out-of-plane structures with high aspect ratios.

Main Methods:

  • Utilized laser-induced forward transfer (LIFT) to deposit and pattern metals.
  • Employed a multimaterial LIFT approach for fabricating devices with multiple metal components.
  • Characterized the dimensions and morphology of the fabricated microdevices.
