The applicability of the 40 TRIZ principles in design for additive manufacturing

The theory of inventive problem solving methodology (TRIZ) is a well-established accelerator to support problem solving by linking specific engineering problems and solutions to general patterns. TRIZ can be applied in conjunction with Design for Additive Manufacturing (DFAM) to create novel geometries, shapes, and enhanced functionalities. In this study, the applicability for DFAM of each of the 40 inventive principles of TRIZ is evaluated and classified. Examples for three TRIZ principles (i.e. asymmetry, nested doll, blessing in disguise) are evaluated further in the context of DFAM, outlining their advantages in functionality and performance. This study is particularly helpful to practitioners who are unfamiliar with the concept of DFAM. © 2018, Danube Adria Association for Automation and Manufacturing, DAAAM.
