Structural Joint

Mold and Manufacture 

In this project I developed and designed a structural joint that is a basic unit that is able to connect with another identical unit to create a 3D complex structure. The objective of the task was to create a plaster mold that imitate an inductrial mold. The plaster mold should allow casting of many different materials, multiple times. 

The structural joint is designed with bi-directionally screw-like shaped edges and a hollow midsection in the shape of the negative space of the edges. The twist in both sides of the joint enables a strong connection between every two units. The top and bottom surfaces of the joints were left flat, to enable interchanging of sections of the plaster mold as wanted or required.

I designed the model using SolidWorks and printed it in a 3D printer. I then created three different plaster molds; each mold holds a different amount of parts and inserts (while some were 3D printed and others were casted from plaster) to create ultimate precision.

Materials: Plaster, Polyurethane, Epoxy, Wax, Polyester and PLA.
