Additional Research on Bone-Like Infill

It can be tough to find the perfect balance between weight and strength when it comes to infill optimization, but earlier this year a group of researchers from the Technical University of Munich, the Technical University of Denmark, and Delft University of Technology developed a new type of infill, inspired by the naturally occurring structure of trabecular bone, that gives an object durable strength without making it too heavy. The research team's work built on voxel-wise topology optimization, and they designed a complex mathematical algorithm to generate an infill that resembles bone's porous structure. The team determined that its trabecular bone-like structure was promising for 3D printing, especially of large, lightweight parts, and the 3D printed structures held up well under tests for robustness and strength. However, the researchers did note that further work needed to be done in order to further optimize their new bone-like infill, and recently made a big step forward in their work.
