| Abstract: | Based on selective laser sintering(SLS) rapid plastic prototype with precision casting technology, metallic parts are made. The ther mal degradation characteristics of plastic powder for prototype is studied . The rapid casting process from 3D solid mould to metallic parts was designed. The preparation of ceramic shell and casting process of metallic parts are exp ounded and the part accuracy is measured. |
