This paper presents a simple process that allows for isolated metal features to be easily defined on the surface of 3D printed micro parts. The process makes use of a standard low cost sputter coating system to quickly deposit metal layers of approximately 100 nm thickness on to the surface of polymer micro parts. The inclusion of inbuilt masking features on the surface of the polymer parts ensure that the conformal metal layer can be effectively broken to create electrically isolated metal features. Using the process a series of polymer micro probes are created and metalized to form electrically conducting, but isolated probe needles. In addition a polymer micro gripper with an inbuilt thermal actuator is demonstrated. © 2012 The Authors. Published by Elsevier Ltd.
