Design firm Van der Kallen has developed a circular furniture line. By using modular components a stool can be disassembled and recycled into a bench or a table. One of the crucial components of this concept is a metal welded connector, used to join the various wooden beams. Downside of this metal connector is that recycling metal is very energy intensive.
Van der Kallen asked Fransiscó to create a more sustainable alternative to the metal connector. As a case study a stool was developed that:
Topology Optimisation was used to create optimised connector that fulfilled the requirements while using the minimal amount of material. The first prototype iterations were 3D printed with biodegradable plastic.
Later iterations use SLS polyamide using white EcoPowder, as shown on the pictures on the left. The stool has been showcased at the 2016 Dutch Design Week in Eindhoven.
