摘要

During this grant we installed a 3D Systems SLA 250/40 stereolithographyapparatus, and used it to directly fabricate ceramic green bodies from ultraviolet (UV) curable solutions which contain dispersed ceramic powders. We emphasized SLA of alumina as a structural ceramic and for investment casting cores. Viscosity was reduced with improved dispersion. The quality of the prototypes was improved by determination of appropriate build styles, and by optimization of photoinitiators and photoresins. The latter were studied by photo-differential scanning calorimetry, and photo-rheology.
