抄録

Complicated ceramics structures were designed by three-dimensional computer graphics and fabricated by using Stereolithographic processes. Photosensitive acrylic resin including with the ceramics particles were spread on a substrate by using a mechanical knife edge. An ultraviolet laser beam of 355 nm in wavelength was focused into 100 μm in diameter and scanned to draw a cross sectional solid pattern. A composite precursor was obtained successfully thorough continuous laminations. The ceramics component could be created by dewaxing and sintering. In this investigation, sound absorption structure with structural property of Helmholtz chamber were designed and fabricated by this process. Sound wave generated by thermal spraying was controlled by the Helmholtz structure. The frequency spectra were plotted by computational fluid dynamics and acoustic simulation. According to the theoretical procedure, a soundproof equipment for gas flame noise from thermal spraying were designed and fabricated by stereolithography.
