Investigation into Development of Transfer Type for Variable Lamination Manufacturing Process and Apparatus

단속형 재료 공급식 가변 적층 쾌속조형공정 및 장치 개발에 관한 연구

A new rapid prototyping process, as a transfer type of Variable Lamination Manufacturing by using expandable polystyrene foam (VLM-ST), has been developed to reduce building time, apparatus cost including the introduction and the maintenance and additional post-processing. The objective of this study is to propose a VLM-ST process and to develop an apparatus for implementation of the process. Design criteria of the apparatus were defined and the techniques were proposed to satisfy the design criterion. In order to examine the efficiency and applicability of the developed process, various three-dimensional shapes, such as a world-cup logo, a knob shape and a character, Son-o-kong, were fabricated on the apparatus in which unit shape layer (USL) was generated to build up each layer.
