Abstract


Rapid prototyping technology is an advanced manufacturing technology developed in the late 1980s , the technology development to today , has to mature and improve its application areas covering almost the various industries in the manufacturing field . However Fused Deposition Modeling (FDM) technology as a rapid prototyping technology , has the advantages of low running costs , parts can be sanded , lightweight equipment , and environmental protection . In view of such a wide range of applications and the many advantages of the FDM process , independently developed a set of mature FDM rapid prototyping equipment and development toward commercialization , there must be a lot of development potential . In this paper, for the structural design and optimization of mechanical system FDM rapid prototyping equipment to conduct a comprehensive in-depth study . First , through the comparative analysis of the structure of the traditional FDM equipment at home and abroad , a complete set of structural design , the use of three-dimensional the entity design software UG for parametric design and virtual assembly of the major parts of the structural design , get the whole complete three-dimensional model of the mechanical system . Then, using the finite element analysis method to validate the safety and stability of the whole mechanical system , on the mechanical structure at the same time to be optimized and improved . When the performance of mechanical systems to meet the design requirements , began to put into the actual production of the prototype . At present , the study of the subject has achieved initial results , the first experimental prototype debugging has been completed , in depth study of the process of its parts process . The research methods have some practical value , for similar large-scale structure of the design and structural optimization and transformation project is very important .
