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.
