Assistant professor Jun Wu of the faculty of IDE will present his research to science journalists on Friday 16 June, at De Rode Hoed in Amsterdam during the NWO event Bessensap. He will show how natural evolutionary processes can help create strong internal structures for 3D prints.

In his talk, Jun explains how natural evolution processes can help to design more efficient and robust 3D infill structures. Such structures, although invisible from the outside, determine the mechanical strength of 3D-printed objects. It is therefore important to find structures that are mechanically strong and lightweight (to keep the material costs of 3D prints as low as possible).

In order to develop solid internal structures for 3D prints, Jun was inspired by the natural internal structure of human bones. Through an evolutionary process, these natural objects grow to a robust status to efficiently sustain external forces. In the bone we can identify highly optimised microstructures. These spongy microstructures are lightweight but have been organised in a smart way to provide our body firmness and support the various forces we experience in daily life. Jun developed an algorithm that can generate these bony microstructures.

The Bessensap event (‘Berry Juice’) is organised annually by NWO in collaboration with the Netherlands Society for Science Journalism (VWN) to stimulate meetings and exchange of knowledge between researchers and the press. Throughout the day, there are various presentations, workshops and debates. Entrance is free. Click here for more information about and to register for Bessensap.
