ThinKing November – Combination of topology optimization and additive manufacturing enables 3D printing of lightweight porous structures



To materialize or not to materialize – that is no longer the question in additive manufacturing. The new software tool TOPOAD developed by the German Institute for Control Engineering of Machine Tools and Manufacturing Units (ISW) at the University of Stuttgart in collaboration with the private company MESHPARTS GmbH allows 3D printing of porous structures with varying material density.

The algorithm developed by MESHPARTS offers the advantage of being able to regulate the density between zero and one. The result of this optimization strategy is a lightweight load oriented object that is inspired by the structure of a human bone and which can be manufactured directly or edited through CAD programs. The whole developement process is digital.

The Development Agency for Lightweighting Baden-Wuerttemberg is proud to present this innovation as its November ThinKing. The Leichtbau BW GmbH hands out this distinction each month to feature impressive products and innovations in the lightweighting sector in Baden-Wuerttemberg.
