  • Patent number: 11338511
    Abstract: An additive manufacturing system, and associated methods, comprise an image projection system comprising a plurality of image projectors that project a composite image onto a build area within a resin pool. The composite image comprises a plurality of sub-images arranged in an array. The properties of each sub-image and the alignment of the position of each sub image within the composite image can be adjusted using a stack of filters comprising: 1) an irradiance mask that normalizes irradiance, 2) a gamma adjustment mask that adjusts sub-image energy based on a reactivity of the resin, 3) a warp correction filter that provides geometric correction, and 4) an edge blending bar at one or more sub-image edges.

  • Publication number: 20220105677
    Abstract: Methods of creating additive manufactured parts include selectively dispensing a second composition onto a top surface of a first composition in a vat. The second composition is dispensed in a shape area according to a layer of a part to be created by additive manufacturing. Polymerization components for formation of the layer are kept separate from each other until the dispensing, with at least one of the polymerization components being in the second composition. The top surface is illuminated to expose the first composition and the second composition to light having a polymerization wavelength, thereby causing polymerization of the layer of the part only in the shape area where the second composition was dispensed.

  • Patent number: 11290704
    Abstract: A method and corresponding system for reconstructing the surface geometry of a three-dimensional object is disclosed. The system comprises a cluster of heterogeneous sensors, including a two-dimensional high-resolution camera and a three-dimensional depth camera, and a turntable operable to rotate incrementally. In operation, the turntable is rotated to first and second positions and two-dimensional and three-dimensional data sets are obtained using the two-dimensional high-resolution camera and the three-dimensional depth camera. Corresponding features from the two-dimensional data sets are identified and used to identify the same corresponding features in the three-dimensional data sets. The three-dimensional corresponding features are used to calculate a three-dimensional homography, which is used to align the three-dimensional data sets. Following alignment, a three-dimensional mesh is generated from the aligned data sets.

  • Patent number: 11260580
    Abstract: In some embodiments, a photoreactive 3D printing system and methods comprise providing a system with a resin tub comprising a membrane, wherein the membrane rests on a physical tension element such that increasing downward force on the resin tub induces increasing tension on the membrane. The system also comprises a plurality of sensors comprising a resin bulk temperature sensor, and a print recipe comprising information for each layer in a 3D printed part to be built on the print platform. In some embodiments, a resin bulk temperature is measured, and the information in the print recipe, including information related to the downward force on the resin tub, is updated during a printing run based on the resin bulk temperature measurement. In some embodiments, the print recipe can be updated during a printing run based on input from at least two sensors of the plurality of sensors.

  • Patent number: 11178391
    Abstract: The present subject matter relates to examples of color calibration of image handling units. In an example, color settings of a flash light unit of a projector unit of a computing system may be calibrated with reference to a target calibration point. The flash light unit may function as an illumination source for an image capturing unit of the computing system. Further, based on the target calibration point and an image captured by the image capturing unit under illumination provided by the flash light unit, the color settings of the image capturing unit may be calibrated to synchronize the color settings of the image capturing unit to the color settings of the flash light unit.

  • Patent number: 11110650
    Abstract: Methods of creating additive manufactured parts include providing a first composition in a vat, where the first composition is a liquid with a first viscosity. A build platform is placed adjacent to and submerged under a top surface of the first composition. A second composition is dispensed on the top surface, the second composition having a second viscosity and being dispensed in a shape area according to a part to be created. The top surface is illuminated to expose the first composition and second composition to light having a polymerization wavelength, thereby causing polymerization of at least one of the first composition or second composition. In some embodiments, the first composition is a base resin that is absent of a photoinitiator, and the second composition is a photoinitiator solution. The photoinitiator solution may have a second viscosity that is less than the first viscosity of the base resin.

  • Publication number: 20210170685
    Abstract: Methods of producing an additive manufactured part with a smooth surface finish and customized properties include creating a compensated design that serves as a print recipe for an additive manufacturing process for a part, where the creating comprises modifying a desired design with a geometric offset correction to compensate for a first portion of an uncured surface finish material to be retained on the part. A spinning device is provided that has a platform. The part is formed with the additive manufacturing process and secured to the platform, where the part is at least partially wetted with the uncured surface finish material. The platform is rotated, where a second portion of the uncured surface finish material is removed due to forces imparted by the rotating. The uncured surface finish material is chosen to customize a property of the part.
