BONE is a concept for the creation of tools through generative design and selective laser sintering. An algorithm is used to calculates bone-like structures, which are light-weight, yet durable. These structures can be used in tools. The concept aims to provide a near infinite toolbox, using a computer and an SLS machine. This setup, including a medium like steel powder, can be utilised to overcome scarcity of resources in certain environments. One potential field of application is space travel.
