Modular designs have gained popularity because they can generally address manufacturing efficiency, reusability, and sustainability concerns. Here, we contribute to the growing field by proposing a fully automatic design method for modules utilized in several products. Our manufacturing-aware procedure is composed of three consecutive steps: (i) free-material optimization for obtaining the optimal spatially distributed elasticity tensors, (ii) hierarchical clustering of the stiffness tensors directly into a given number of modules while allowing for their flipping, and (iii) single-scale topology optimization with manufacturing aspects to design the final topology of mechanically compatible modules. These aspects include connectivity constraints to ensure the integrity of all modules and the three-field projection to account for manufacturing inaccuracies. We illustrate the entire procedure with the design and fabrication of eight different reusable modules assembled into well-functioning modular inverter and gripper mechanisms. These mechanisms were 3D printed and subjected to mechanical testing using an in-house testing machine and digital image correlation. The experimental results show excellent agreement between the predicted and observed behavior and highlight the potential of the method for scalable additive manufacturing. |
