ABSTRACT

The Stereolithography method is studied by several universities, such as TU, XJU, HUST. Since 1992, the Stereolithography Apparatus (SLA) has been built up in the CLRF and TU. This is the first SLA equipment in China. XJU gave a systematic study on the SLA. According to their experiences, the most important problem is automatic stability of the liquid surface of photoresin. They improved the structure of their new RP machine, and got much better results.
