Abstract Scope |
Multi-material additive manufacturing (MMAM) has recently emerged as a prominent research area due to the significant enhancement in design flexibility. In this work, we adapted a density-based topology optimisation framework called alternating active phase (AAP) algorithm to design a multi-material Messerschmitt-Bolkow-Blohm (MBB) beam. The optimised design was fabricated via multi-material laser powder bed fusion (MM-LPBF), a metal AM process. Both finite element analysis (FEA) and three-point bending tests were conducted to assess the effectiveness of computational optimisation. This research also serves as the early-stage proof of concept in printing multi-material metal structures via MM-LPBF. Preliminary results have shown great potential in balancing competing objectives (i.e. mechanical and thermal), guiding the future work of multi-material design optimisation and fabrication. |
