Abstract: How to make large-scale prototype is one of the hotspots of the development of rapid prototyping (RP) technology. Long time consumption is one of the difficulties. Laminated object manufacturing (LOM) has particular advantage in forming large-scale prototype. A new method—dynamic divisional parallel scanning system aimed to LOM is put forward. Analysis and test achievement show that by this method the forming efficiency can be improved remarkably.
