Abstract: A method for producing a component from two or more sub-components includes the steps of: producing each of the sub-components using an additive manufacturing process in which a resin, which is radiant-energy-curable, is partially cured using a selective application of radiant energy, wherein each sub-component includes a joint surface in which the resin is partially cured which is cured to a lesser degree than the remainder of the respective sub-component, so as to leave the joint surfaces in a condition suitable for bonding; assembling the sub-components with their respective joint surfaces in mutual contact; and performing a secondary cure of the partially-cured resin at the joint surfaces using an application of radiant energy, so as to further cure the partially-cured resin and bond the sub-components to each other, thereby forming the component.

Abstract: A method for producing a component layer-by-layer. The method includes the steps of: depositing particulate material to form a layer of particulate material having a first area over a build platform; applying at least one exothermic material over the build platform so that a selected portion of the first area is uniformly coated with the exothermic material; selectively sintering a second area of the layer smaller than the selected portion of first area, using an application of radiant energy to trigger an exothermic reaction in the at least one exothermic material, in a specific pattern that defines the geometry of a cross-sectional layer of the component; and repeating the steps of depositing, applying, and sintering for a plurality of layers until the component is complete.

Abstract: A method is provided for controlling an additive manufacturing process in which a radiant energy source is used to selectively cure a layer of resin to form a workpiece. The method includes: curing a first portion of the layer using a first application of radiant energy at a first energy level; and curing a second portion of the layer using a second application of radiant energy at a second energy level different from the first energy level.

Abstract: An additive manufacturing apparatus includes a support plate defining a window and a resin support configured to support an uncured layer of resin. A stage is configured to hold one or more cured layers of the resin to form a component positioned opposite a support plate. A radiant energy device is positioned on an opposite side of the resin support from the stage and is operable to project radiant energy in a grid through the window. The grid and/or pixels thereof are intelligently shifted to efficiently print one or more layers of a component.

Abstract: The present disclosure generally relates to methods for additive manufacturing (AM) that utilize a computer aided design (CAD) model of a part to develop a layer representation of the part. The method includes: determining a build layer thickness of an additive manufacturing apparatus; identifying a feature of the part within the model; determining that the feature is not aligned along the z-axis based on the build layer thickness; and moving the feature within the model along the z-axis by a feature offset such that the feature is aligned along the z-axis.

Abstract: A method of making a workpiece in an additive manufacturing process includes determining a preferred angular orientation of the grid array about a build axis extending perpendicular to a layer to be built for a first layer of a workpiece. The preferred angular orientation is selected to align an edge of one or more pixels with an edge of the layer of the workpiece being built. The method further includes orienting a patterned image of radiant energy to the preferred angular orientation by rotating a projector before solidifying a portion of a resin that forms the first layer of the workpiece.
