As a Research Assistant at Wentworth, our Director designed a mold system that integrated with a 6 axis robotic arm. The mold assembly consists of CNC milled birch plywood, fabric inserts and hardware. The shape of the frame (here as a parallelogram) could be any 2D shape driven by project specific design requirements.
The laser cut subframe of the fabric inserts can integrate with any shape of the frame. This assembly design gives a second dimension of variability in the precise positioning of the robotic arm while gravity pulls the liquid. This variability can be parametrically controlled to optimize the thickness and positioning of the pour. Additional fixtures can be introduced to make punctures of varying sizes and angles.
The resulting cast parts can be aggregated into wall systems as rain screens, sun shading and thermal masses.
