For this reason,some new methods,technics and application examples of rapid manufacturing casting moulds based on the laminated object manufacturing(LOM)and selective laser sintering(SLS) series rapid prototyping (RP) system developed by Huazhong University of Science and Technology(HUST) are presented in this paper.

Curl distortion in the process of selective laser sintering(SLS) greatly affects the accuracy of the shaped parts by SLS.

Application of Partite Wax Pattern Combination Technology;

Study of the Making Technology of the Wax Pattern for Shovel Casting;

In order to rapidly,cheaply and flexibly produce single or low-volume precision castings by investment casting,technology of SLS Prototype Wax Pattern instead of Die Wax pattern was investigated in the paper.

New Process of NC Forming of Casting Waxen Mould for Complex Parts;

By dopting RP technique to making waxen pattern in exploitation and produce of new products in small batch investment casting,the press patte don't need making,which can shorten the prodoction peroids,reduce the cost and improve the efficiency of products exploitation and produce.

Study on high strength wax and its use on large complicated integrated thin wall titanium investment casting;
