The research of TRIZ-assisted additive manufacturing functional period construction process

Abstract

Current research on additive manufacturing predominantly focuses on the structural and parameter levels, with relatively limited exploration on the functional level. This study investigates the construction process of the functional period in additive manufacturing by adapting the analysis and problem-solving tools from TRIZ theory at the functional level. First, the cyclic behavior of the additive manufacturing process is elucidated, followed by an analysis of the functional period embedded within the process. A classification method for complexity is introduced and the role of the functional period in transforming types of complexity is explained. Second, the analytic tools and problem-solving tools within TRIZ theory that are applicable to the additive manufacturing process have been summarized, leading to the establishment of functional solution acquisition paths specific to the additive manufacturing process. Third, based on these functional solution acquisition paths, a process model for constructing the functional period in additive manufacturing is proposed. Finally, the proposed functional period construction process model is applied to the porosity control of tin bronze samples. Experimental results demonstrate that the density of the tin bronze sample increased by over 4 %, confirming the feasibility of the TRIZ-assisted functional period construction process in additive manufacturing.
