Abstract
The additive manufacturing is very useful for prototyping in design analysis and functional testing. It can reduce lead-time and costs for product development. As one of open issues, it is difficult to make larger models than the machine size and take long time for making solid models because processing point is limited in a very small area. So, we propose an approach that we divide one object into some segments, fabricate them with hollow space by using 3D-printers, and then run polymer into the hollow space by a vacuum pomp to reinforce the model strength. In the present paper, some experiments are conducted to evaluate this approach.
