Abstract Scope |
We present an additive manufacturing process where surface-tension of a photopolymer resin is used to suspend a large vertical liquid-film that is selectively and continuously polymerized using digital light processing. The vertical film is stabilized by a continuous downward creeping flow of resin which also recoats the parts as the part is being pulled from the film along a horizontal build direction. The advantage of selectively polymerizing on a vertical film is the reduced amount of resin required throughout the manufacturing process and fewer to none support structures on the 3D-printed geometries. A proof of concept of such a machine, process, and extension of this work into embedding multiple spatially steered fibers are discussed in this paper. |
