Description
In precision casting where production is of comparatively small scale, the use of photo-solidified polymer models in place of conventional lost-wax models can be recommended. Precision casting products using photo-solidified polymer models have the tendency for unstable product size compared with precision casting products using conventional lost-wax models. Dimensional changes in honeycomb structure models made by SL5170 epoxy photo-solidified polymer was measured during and after building, and experiments were conducted to investigate the cause of dimensional changes. As a results, it was confirmed that during building, there exists a swelling phenomenon due to liquid polymer although the rate of dimensional change is extremely small. It was found that after building, there exists a swelling phenomenon due to moisture in the atmosphere. The rate was comparatively large, that it had a bad influence on the quality of precision casting products.
