ROBust Optimisation in Design for Additive Manufacturing

Purpose and goal

One type of network structures that has shown great potential in 3D printing is TPMS-based structures, where the best-known type is the Gyroid structure. The aim of this project was to build knowledge about TPMS-based structures in order to efficiently 3D print lightweight components designed with these network structures in different materials. The project has developed new optimization methodology for this purpose, as well as developed and carried out mechanical testing and characterization of several different types of TPMS-based structures in several different materials.

Expected results and effects

New optimization methodology for TPMS-based structures is developed and implemented in 3D. By using the new methodology, ultra-light components and better material utilization can be accomplished. Mechanical properties are tested and verified for several different types of TPMS-based network structures in several different materials. It is confirmed that static properties are satisfied by the network structures. This is a first important design criterion that is fulfilled. The TPMS-based network structures are also characterized with CT and SEM.

Planned approach and implementation

The project has been implemented in the following four work packages: WP2: Development of optimization methodology WP3: Characterization with CT and SEM WP4: Mechanical testing WP5: Demonstrators in close cooperation between the parties of the project: Karlstad University, Örebro University, Bofors, Epiroc, Lasertech and Siemens-Energy. Regular project meetings have been held both physically and via Zoom to report results and drive the project forward. The project ended with a physical 2-day conference where the project leaders of the work packages presented their results.
