SSVP can realize highly complex geometries and functional assemblies without requiring manual support removal. For example, a functional gear train can be directly produced without any assembly steps (Fig. ). Additionally, intricate lattice structures can be fabricated with overhangs that would typically require the removal of extensive internal support structures (Fig. ). Parts can also be stacked within the build volume, allowing large numbers of components to be printed simultaneously regardless of their orientation, then released upon support dissolution (Fig. ). And, if minimization of the support dissolution time is desirable, the dissolvable material can be printed only at the interface between the crosslinked part and the support structures (Fig. ). Here, a denture base is printed by SSVP with dissolvable support interfaces and then mated with a set of artificial teeth printed separately by conventional VP, to form an assembled denture model. Detailed part dimensions are shown in Figure . From left to right: a rendering of the two-wavelength CAD, the as-printed object, and the object after support dissolution. All scale bars are 1 cm in length. (A) A three-part, print-in-place assembly with interlocking, functional gears (Movie S1). (B) A gyroid lattice and a reentrant lattice, both with overhanging features that require the use of supports. Support material is dissolved from thin channels in the interior of the lattices. (C) Volumetrically packed buttons. The printed support material has channels to reduce resin usage and facilitate solvent access for dissolution. The inset side length is 1 cm. (D) A printed denture base and assembled denture model. For this print, only a thin interface between the supports and the object was printed with soluble material. This allows for fast and automatable support removal in a solvent. The teeth inserts were printed with a commercial resin in a separate VP printer, and assembled to the SSVP-printed base.
