Most additive manufacturing machines, also known as 3D printers, work in the Cartesian coordinate system, printing in an XY plane and building up in the vertical Z direction. Multi-axis and cylindrical additive manufacturing methods do exist. However, cylindrical methods, both in academia and industry, are limited to systems where material is actively deposited onto an existing cylinder. This low-fidelity prototype that utilizes a modified DLP projector to selectively cure resin on a rotating mandrel. Unlike existing forms of cylindrical printing, the mandrel is completely submerged in a vat of photocurable resin.
