Methods for manufacturing an item that include obtaining a component support assembly having at least a first component on a top surface of a planar support member, and placing a frame onto the planar support member's top surface or around the planar support member such that the frame surrounds the first component. The frame has at least one side member, and an inner surface of the side member defines a frame cavity. The methods may also include depositing a second component material into the frame cavity and onto the component support assembly, and allowing the second component material to harden to form a second component that is secured to the first component and the planar support member's top surface. The methods may include removing the frame from the unfinished item, and removing the planar support member from the first and second components to reveal a bottom surface of the item.
