Microrobotic devices have been widely investigated as promising alternatives to convent biomedical technologies. Microrobotic devices having spatially complex structures such as the helical structures has generally been manufactured by using three-dimensional (3D) printing technologies. However, due to the limitations of the extrusion and lamination processes, microrobotic devices can be constructed with low degree of precision and can have poor surface roughness under the 3D printing technologies. This may cause undesirable damages to the human body tissues. Furthermore, 3D printing requires long processing time due to postprocessing to remove unwanted body parts. To improve surface quality and shorten processing time, this research uses laser machining. Before directly applying laser machining to fabricate microrobotic devices, understanding laser ablation characteristics on Acrylonitrile Butadiene Styrene (ABS), which is a common material used for 3D printing, is necessary. Laser ablation characteristics on this material are investigated with a variation of laser parameters such as a scanning speed and the number of scanning passes. An ablation depth prediction model is suggested. Laser ablation on ABS shows a high aspect ratio (~327.2). Furthermore, color changes around the ablation zone can be utilized for the indication to estimate the absorbed laser energy indirectly.
