Zero adventure rapid design/manufacturing can be realized with rapid prototypes of 3D CAD of products. Rapid prototyping has been an effective tool of R&D of new products. A novel rapid prototyping and manufacturing (RP&M) technique is brought forward. The principle of the process is to form layered sections and to make the prototype or part layer by layer by deflection projection of electric charged powder granules passing through electric or magnetic field and by controllable line and field scan of the powder granule beam. The feasibility issue of the process is theoretically and experimentally investigated.It shows that deflection projection of electric charged powder granules beam passing through electric field can be significant and feasible to the rapid prototyping technique.展开更多

This paper is concerned with the software system aspects of the selective laser sintering (SLS),i.e.the issues that deal with an external geometric CAD model to automatically control the physical layering fabrication process as directly as possible ,regardless of the source of the model. The general issues are described and some key methods are given in this paper.展开更多

To facilitate application of RP&M technology as an enabling technology in product development and manufacturing, our center has done a series of pojects covering RP theory (modern shaping science), new RP processes and equipment,rapid tooling technology and rapid product development systems. With the STEP protocol and product modeling technology, RP&M technology can be integrated into CIMS to form a new subsystem, the free form manufacturing subsystem. The subsystem architecture is investigated in this paper.展开更多
