Laser-Based Manufacturing of Ceramics: A Review

Abstract

Ceramics are widely used in microelectronics, semiconductor manufacturing, medical devices, aerospace, and aviation, cutting tools, precision optics, MEMS and NEMS devices, insulating components, and ceramic molds. But the fabrication and machining of the ceramic-based materials by conventional processes are always difficult due to their higher hardness and mechanical properties. Therefore, advanced manufacturing techniques are being preferred for these advanced materials, and out of that, laser-based processes are widely used. The benefits of laser fabrication and machining of ceramics include high precision, reduced thermal damage, non-contact processing, and the ability to work with complex geometries. Laser technology continues to advance, enabling even more intricate and diverse applications for ceramics in a wide range of industries. This paper explains various laser based ceramic processing techniques, such as selective laser sintering and melting, and laser machining techniques, such as laser drilling, etc. Identifying and optimizing the process parameters that influence the output quality of laser processed parts is the key technique to improving the quality, which is also focused on in this paper. It aims to facilitate the researchers by providing knowledge on laser-based manufacturing of ceramics and their composites to establish the field further.

High-Power Femtosecond Laser Processing of SiC Ceramics with Optimized Material Removal Rate

“…Current research on the femtosecond laser processing of SiC and other ceramics has focused on the existing limitations, such as surface oxidation, the processing of fine structures (e.g., micro-holes, micro-grooves), and material thermal damage [18][19][20][21][22][23]. Most of the available studies address parameter optimization, processing path motion strategy, beam shaping, and the effects of assist gas [24][25][26].…”
