Recently, the lead-time of a product is to be shortened in order to satisfy consumer's demand. It is thus important to reduce the manufacturing time and the cost of 3D-shaped microstructures. Micro-Electro-Mechanical Systems (MEMS) and devices are usually fabricated by lithography-based methods. Above method is not flexible for the rapid manufacture of 3D-shaped microstructures because it depends on work's experiences and requires excessive cost and time for making many masks. In this paper, the effective laser micromachining is developed to fabricate UV sensitive polymer microstructures using laser ablation. The proposed process, named by laser microRP, is a very useful method on rapid manufacturing for 3D-shaped microstructures.
