Abstract: An additive manufacturing apparatus includes a support plate and a stage configured to hold a component formed of one or more cured layers of a resin. An actuator assembly is configured to change a relative position of the stage relative the support plate. A radiant energy device is positioned opposite to the stage such that it is operable to generate and project radiant energy in a pattern. A peeling device is positioned downstream of the window. The actuator assembly is configured to move the stage simultaneously with a resin support over the peeling device in an X-axis direction.

Abstract: A method for forming a part layer by layer using an additive manufacturing apparatus. The additive manufacturing apparatus includes a resin support, a stage, a measuring system, and an actuator configured to change the relative position of the stage and the resin support. The method includes the steps of: performing an additive manufacturing cycle including the following steps: depositing an uncured layer of resin; moving the stage to a target location; curing the uncured layer of resin; and moving the stage away from the target location; repeating the additive manufacturing cycle; performing a measuring process wherein the measuring process includes the following steps: using the measuring system to take a measurement indicative of an actual position of a structure; comparing the actual position of the structure to an expected position of the structure to determine an error; and using the error to modify the target location.

Abstract: A method for producing a functionally graded component layer-by-layer includes: depositing radiant-energy-curable resin on a build surface defined by a resin support, the resin containing filler including at least two groups of particles with different physical properties; allowing the filler to settle such that the groups of particles separate from each other, defining at least two regions within the resin; positioning a stage relative to the build surface so as to define a layer increment in the resin; selectively curing the resin using an radiant energy applied in a specific pattern so as to define the geometry of a cross-sectional layer of the component; moving the build surface and the stage relatively apart so as to separate the component from the build surface; repeating at least the steps of positioning and selectively curing for a plurality of layers, until the component is complete.

Abstract: An additive manufacturing apparatus is disclosed. The apparatus includes a build surface, at least a portion of which is transparent. The apparatus includes a first material depositor operable to deposit a curable resin to form a deposited resin layer on the build surface. A first sensing device is configured to measure the thickness of the deposited resin layer; and wherein the at least one sensing device is configured to generate a signal indicative of the thickness of the deposited resin layer. The first sensing device can be connected to a computer such that the additive manufacturing apparatus is configured to control the thickness of the deposited resin layer. The thickness of the deposited resin layer can be controlled such that it varies from side to side. The thickness can also be controlled such that it varies with time.
