Abstract: An apparatus for manufacturing a three-dimensional article by additive manufacturing includes a processor and an information storage device storing software instructions. In response to execution by the processor, the software instructions cause the apparatus to: receive initial data defining the three-dimensional article having an outer surface, define a shell having the outer surface of the three-dimensional article and an opposing inner surface that defines an inner cavity, define a transition zone between the inner surface of the shell and a boundary that is inside the inner cavity and generally follows the inner surface of the shell, define a lattice of arrayed unit cells that fill the inside of the boundary, the lattice is defined by connected lattice segments, and define transition segments that couple the lattice to the inner surface of the shell.

Abstract: An apparatus for manufacturing a three-dimensional article by additive manufacturing includes a processor and an information storage device. The information storage device includes a non-transient or non-volatile device storing software instructions. In response to execution by the processor, the software instructions cause the apparatus to: receive initial data defining the three-dimensional article having an outer surface, define a shell having the outer surface of the three-dimensional article and an opposing inner surface that defines an inner cavity, define a boundary in the inner cavity that further defines an outer lattice volume between the inner surface of the shell and the boundary and an inner volume inside the boundary, and define a lattice that fills the outer lattice volume.

Abstract: There is provided an additive manufacturing system comprising a vertical stage (also known as a z-stage) that moves the object being created along an axis of motion that is not perpendicular to the image plane (non-parallel to the z-axis of the image plane). By moving the build platform, upon which the additively manufactured object is being supported, along a predetermined axis of motion, such as one adapted to the dominant axis of the object design, the additive manufacturing system is capable of making larger objects, shortening build times, improving part resolution, and/or reducing the volume of photocurable material needed, among other benefits.

Abstract: A three-dimensional (3D) printing system includes a vessel configured to contain a photocurable resin, a coating subsystem including a coater blade, a build plate coupled to a vertical movement mechanism, an imaging system configured to selectively image the photocurable resin at a build plane, and a controller. The controller is configured to operate the vertical movement mechanism to position an upper surface of the build plate at the build plane, translate a lower edge of the coater blade over the build plane along a scan direction, and concurrent with translating the lower edge of the coater blade, operate the imaging system to selectively image the build plane while maintaining an exclusion zone that includes a digital shadow that translates with the coater blade, the digital shadow includes an area of the coater blade and a fluidic wake area that follows the coater blade.

Abstract: A three-dimensional printing system includes a resin vessel, a support tray, a motorized carriage, a light engine, and a controller. The resin vessel has a lower side with a transparent sheet which provides a lower bound for photocurable resin contained within the vessel. The support tray has a lower face for supporting an object being fabricated. The motorized carriage is for supporting and vertically positioning the support tray. The light engine is for projecting radiation up through the transparent sheet to a build plane. The controller operates the motorized carriage and the light engine to fabricate the object. The object includes a vertical arrangement of dental arches suspended from the lower face and a plurality couplings that connect pairs of the dental arches.

The 3D printer includes a 3D print engine for generating articles of manufacture through a layer by layer solidification of a print medium, a transport mechanism, a receiving station, and a controller. The controller is configured to (a) operate the 3D print engine to generate a continuous build platform, (b) concurrently with (a), operate the print engine to generate a plurality of 3D articles of manufacture that are attached to the continuous build platform; and operate the transport mechanism to engage the continuous build platform to transport the continuous build platform along a path that extends between the 3D print engine and the receiving station.
