Abstract: The present application discloses implementations relate to automated generation of interlocking joint features. An example method involves obtaining a virtual model of an object. The virtual model specifies dimensions of a first element, dimensions of a second element, and a spatial relation between the first element and the second element that defines a joint angle. The example method also involves obtaining a relationship that correlates element dimensions and joint angles with cut dimensions. The example method further involves determining cut dimensions for the first element the second element based on the relationship, the dimensions of the first element, the dimensions of the second element, and the joint angle. Modifying the first element and the second element according to the cut dimensions produces interlockable features on the first element and the second element. Additionally, the method involves providing an output signal indicative of the cut dimensions.

Abstract: A 3D printing process may form a 3D object by alternatingly forming layers from a liquid resin and a solid. For instance, when printing a 3D object, the 3D printer may at least partially cure a layer of liquid resin, and before the curing of the resin is complete, dip the semi-cured resin into a vat containing graphene powder so as to create a super strong 3D object. As another example, each semi-cured resin layer could be pressed into a vat of fiberglass such that the fiberglass is coupled to the semi-cured resin. The resin may then be allowed to finish curing before the next layer of resin is formed. In other embodiments, this process could be used to embed sensors in 3D printed objects.
