Abstract: A reconfigurable and reusable flexible membrane mold by which architectural panels and the like can be cast into a variety of different sizes and shapes. The membrane mold includes a pair of mirrored sides that are arranged in spaced, opposing alignment so that a gap between the sides can be filled with casting material. Each side of the mold has a flexible forming membrane with a plurality of receiving cups extending therefrom. An array of actuating pins is coupled to each of the forming membranes by way of ball joints standing atop the actuating pins and ball joint connector heads within which the ball joints are received and retained. The ball joint connector heads are received by and embedded within the receiving cups. The flexible forming membranes are responsive to pushing and pulling forces applied thereto by the actuating pin in order to shape the forming membranes.
