AbstractThis contribution investigates how methods for functional modeling support designers with additive manufacturing. Therefore, two methods for functional modeling are examined. In this contribution a study with 32 participants is presented. The participants solved two consecutive design tasks, in which some participants were supported by functional modeling methods in the second task. The study shows that students have the most difficulties in dealing with the geometric restrictions of Laser Beam Melting (LBM). Furthermore, the support value of functional modeling was not able to be assessed.
