摘要： A rapidly printing 3D nanostructures arrangement, comprising a first photonic source configured to provide photoinitiation energy to a polymer medium via a dynamic light spatial modulator to an excited state to initiate polymerization, a second photonic source configured to selectively provide inhibition energy to the polymerized medium to a depleted state to inhibit polymerization thereby generating a dead zone below a growth zone, the dead zone allows continuous 3D polymerization.

摘要： The present disclosure relates to reinforcing a vehicle pillar. The vehicle pillar includes a corner member and a reinforcement member. The reinforcement member is additively manufactured and may utilize functionally graded materials. The reinforcement member may be directly deposited on the corner member or may be manufactured separately and coupled thereafter to the corner member. The reinforcement member includes a first component, and a second component. Additionally, the reinforcement member may include a third component that extend angularly from the first and second component to form a Y-shaped structure. The reinforcement member can include multiple attachment joints that facilitate consolidating and coupling the reinforcement member with various vehicle components.

摘要： A method of forming a three-dimensional object (e.g. comprised of polyurethane, polyurea, or copolymer thereof) is carried out by: (a) providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween; (b) filling the build region with a polymerizable liquid, the polymerizable liquid comprising a mixture of: (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from the first component; (c) irradiating the build region with light through the optically transparent member to form a solid blocked polymer scaffold and advancing the carrier away from the build surface to form a three-dimensional intermediate having the same shape as, or a shape to be imparted to, the three-dimensional object, with the intermediate containing the second solidifiable component; and then (d) contacting the three-dimensional intermediate to water to form the three-dimensional object.

摘要： This disclosure describes techniques for fabricating a high-resolution, non-cytotoxic and transparent microfluidic device. A material can be selected based on having an optical property with a predetermined degree of transparency to provide viewability of a biological sample through the microfluidic device and a level of cytotoxicity within a predetermined threshold to provide viability of the biological sample within the microfluidic device. An additive manufacturing technique can be selected from a plurality of additive manufacturing techniques for fabricating the microfluidic device based on the selected material to provide a resolution of dimensions of one or more channels of the microfluidic device higher than a predetermined resolution threshold.

摘要： 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.

摘要： A three dimensional printing system for manufacturing a three dimensional article includes a build platform, a light engine, and a controller. The build platform is coupled to a vertical positioning apparatus. The light engine is configured to generate and scan a columnar array of light spots across a build plane. The columnar array of light spots are arranged along a second axis. The light spots are scanned along a first axis. The build plane is laterally defined by mutually perpendicular X and Y axes. In the build plane, the first axis is parallel to the X-axis.

摘要： Disclosed is a three-dimensional object shaping apparatus for forming an object with a desired shape in a three-dimensional space represented by a three-dimensional orthogonal coordinate system of XYZ. The three-dimensional object shaping apparatus includes a light source; a drive mechanism to move the shaping surface parallel to an XY plane in a Z axis direction; an optical scanning unit to scan light emitted from the light source along a Y axis direction perpendicular to the Z axis; and a rotation mechanism to rotate one of the optical scanning unit and the shaping surface relative to each other with respect to the Z axis as a rotation axis, where a pattern of the light to be applied to the shaping surface is controlled by a combination of a rotation of the shaping surface performed by the rotation mechanism and the scanning of the light performed by the optical scanning unit.

摘要： Provided is an attachment for stereolithography apparatuses capable of forming three-dimensional objects having various sizes. The attachment for stereolithography apparatuses includes a base mountable on and demountable from the formation table of a stereolithography apparatus and first and second support members mounted to the base. The base has a rectangular frame shape formed by guides and coupling rods. The first and second support members support a vat in positions in which the distance from an optical engine to the vat is longer than the distance from the optical engine to the formation table, such that the vat is approximately horizontal.

摘要： A method and apparatus for making a three-dimensional object by solidifying a photohardenable material are shown and described. A photohardening inhibitor is admitted into a surface of a photohardenable material through a flexible film to create a “non-solidification zone” where little or no solidification occurs. The non-solidification zone prevents the exposed surface of the photohardenable material from solidifying in contact with the film. The inhibitor tends to cause the film to deform along the build axis, thereby creating a non-planar interface between the photohardenable material and the film, which distorts the resulting three-dimensional object. An apparatus is provided to stabilize the flexible film and eliminate or minimize such deformation.
