Abstract

The microfluidic device needs multi-step fabrication, and this process relatively takes time because it requires meticulous treatment. This approach, using laser engraving, reduces the conventional mold fabrication step which is created by soft lithography in the cleanroom. For biomedical research purposes, a certain dimension of the microfluidic design needs to be achieved. Meanwhile, different material needs different variable setting in laser engraving. This article’s research objectives are seeking the optimum variable to achieve targeted dimension and investigating the influenced parameters lead to better understand the laser engraving fabrication process. The Poly (methyl methacrylate) (PMMA) sheets had been engraved to a particular dimension refers to the mold design that uses in the microfluidic device. The result showed that parameters meet the desired dimension found at values: 1000 for resolution, 95 for power, 500 for frequency, and 60 for speed. It can be noted that these adjusted parameters were performed for a single passage. Moreover, these influenced parameters also had been investigated to see their effect related to the engraving result. The result showed that the speed was the most significant parameter meanwhile the frequency has a stagnant value in the laser engraving process. This study also observed that higher resolution could smoother the rough surface. This study emerges the potential of laser engraving as rapid prototyping machinery for microfluidic technology.
