Abstract
Systems and methods for 3D printing hollow bodies, such as bodies having an exterior cylindrical shape with a hollow interior, are described. Such systems and methods utilize rotatable hollow print base supports having an interior size and/or shape that matches the desired exterior shape of the final printed structure. The printed bodies, methods, and systems enable printing of the desired hollow printed body from the outside-to-inside. They also allow easy production, customization, and modification of internal structures within the printed hollow body.
