Make-up Fabrication of Big or Complex Parts Using the SLA Process

Rapid prototyping is a highly flexible manufacturing technology which can produce big or complex parts without any special fixtures and tools. But it is often a costly and time consuming process to produce big and complex parts. To solve this problem, this paper proposes the makeup fabrication process. The process cuts the CAD models of big or complex parts into several small components. optimizes the building orientation and the layout of the multiple objects and then uses theSLA process to build. The paper discusses the basic process, the discretion rules of the CAD models and the optimization of the layout of multiple objects in the simultaneous building
