Abstract: Methods and apparatuses for additive manufacturing using stereolithography (“SLA”) materials. The apparatus includes a platform for holding an assembly of SLA resin layers. The apparatus also includes a platform for holding an assembly of SLA resin layers. The apparatus also includes a first movable stage for depositing and curing a portion of the liquid SLA resin on the platform, forming a pattern of cured SLA resin. The apparatus also includes a second movable stage for depositing a low-viscosity non-SLA material in voids in the pattern of cured SLA resin. The apparatus also includes a cooler for cooling the low-viscosity non-SLA material below its freezing point until solidified.

Abstract: A system for additively manufacturing a build part. The system includes a build platform configured for disposition within a resin tank, and a light source configured to cure a layer of resin. The layer of resin is disposed adjacent to a pre-cure build surface of the build part. The system also includes a constrained surface located between the build platform and the light source and configured to form a boundary for the layer of resin disposed between the constrained surface and the pre-cure build surface. The constrained surface is configured to vibrate to reduce a separation force required to separate the constrained surface from a post-cure build surface of the build part. The system also includes a vibratory source configured to vibrate the constrained surface.
