Abstract

This article presents the experimental investigation of the ability of a novel technique called Selective Laser Baking(SLB) to fabricate 3D printed micro-optics with Polydimethylsiloxane (PDMS), which has numerous applications due to its characteristics. SLB is a direct writing laser method that uses the thermal effect of a laser beam to fabricate 3D parts. In this method, absorption of the laser heats the emitted locations; increasing the temperature accelerates the hardening procedure and causes the PDMS mixture to get hard immediately. This fabrication technique is a unique method that contributes to fabricating 3D print with two-based thermoset polymers. In addition to analyzing the laser beam heat transfer in PDMS with COMSOL Multiphysics, multiple two and three-dimensional experiments were performed to investigate the optimal printing parameters. Experimental results have shown the ability of the SLB 3D printing method to fabricate microstructures such as micro-optics and microfluidics.
