This Plexus concept, by industrial designer Subinay Malhotra, combines generative design and a host of proposed production methods, from metal 3D printing to casting. The end products are meant to be connectors for dowels.
Malhotra's laid out his thinking in detail:
"Goal: Developing a 3 dimensional joinery system to create modular units adapting to a range of products from furniture to architectural supports. Altering, designing and finishing metal forms into generative meshes, uniquely inspired by nature, incorporating material reduction and supporting sustainability."
