Design verification through tolerance stack up analysis of mechanical assembly for 3d printed components

Abstract

Automobile sector encounters new challenges and hurdles every day. New design trends and day-by-day technology advancement from research, push companies to develop new competitive models. Automobile manufacturing is one of the most competitive business domains where every organization will thrive to prove themselves in the society and market. In order to increase the production rate of the company, automobile manufactures can increase the efficiency of their research and development process enabling them to get their product in the market with less time and better quality. Additive manufacturing is being used in the prototyping, tool and dies making process due to less time, labour efforts and cost. But the hurdles faced by company in additive manufacturing are poor dimensional accuracies and tolerances. Automotive industries find difficult to get their exact dimensional tolerance values resulting in failure of the component. In this paper authors demonstrated tolerances stack-up analysis through a case study of critical 3D printed components and its assembly used in automobile. This paper provides a review of role and future scope of additive manufacturing in automobile industries.
