Experimental shrinkage study of ceramic DLP 3D printed parts after firing green bodies in a KILN

Popis výsledku v původním jazyce

The objective of this work was to investigate dimensional parameters of 3D printed parts from glass ceramic photopolymer before and after debinding and sintering in a kiln. During experiments, batches of green bodies were printed with different layer thickness and curing strategy. We used 3D printer with ultraviolet LED as a light power source. The peak of intensity of the UV LED was in the range from 385 to 405 nm. DLP projector from Texas Instruments was used for mask projection. After printing, each batch of green bodies was cleaned and post-cured in a UV chamber. Then their dimensions were measured, overgrowth of each sample was calculated. The next stage of the experiment was kiln firing according to special firing schedule. Dimensions of final parts were measured again, and their shrinkage was calculated. The experiment proved the high influence of printing parameters on the overgrowth of models and almost no influence on shrinkage of parts after firing.
