Naslov predavanja: THE EFFECT OF THERMAL HISTORY AND PRODUCTION PARAMETERS IN THE ACCURACY OF FUNCTIONAL COMPONENTS IN ADDITIVE MANUFACTURING

Apstrakt: The evolving technology of Additive Manufacturing (AM) is posing novel challenges in manufacturing practice since nowadays functional, end-use components and assemblies are produced by commercially available AM equipment. In order to safeguard the functionality and the interchangeability of a part, the designer must clearly denote a set of geometrical product specifications (GPS) in the 3D model or in the engineering drawing. The goal of this lecture is to investigate the effect of thermal history and AM parameters in the accuracy of functional components and to address the issue of creating a novel methodology for designing these components in order to eliminate geometrical and dimensional deviations. For this purpose, the results of FE analysis for a popular AM test case will be presented in comparison with experimental measurements. Common AM defects as well as bad practices will also be discussed.

Zbog trenutne epidemiološke situacije, maksimalnan broj slušalaca u sali je pet (uključujući predavača i organizatore seminara). Predavanja se mogu pratiti na daljinu preko linka
