摘要: A method and system for microscale 3D printing achieve high-fidelity fabrication through the control of the light exposure time. A single pulse of light is used to initiate polymerization of a pre-polymer solution to minimize scattering-induced resolution deterioration. The printed object is fabricated in a layer-by-layer construction where each layer is formed through exposure to a single light pulse.

摘要: The invention relates to an additive manufacturing method in which a component (10, 42, 43, 44, 45) is produced in layers using an energy beam (8, 41, 58) which solidifies a starting material (4) and is irradiated by energy beam irradiating means (9, 22, 31, 38, 39, 55, 59, 61) while the starting material (4) is held by a base surface (3, 15, 30, 36, 52) arranged on a base element (2, 16, 29, 35, 51). While the starting material (4) is being irradiated with the energy beam (8, 41, 58), the base element (2, 16, 29, 35, 51) is moved by a rotational component which has a base element rotational axis, wherein the starting material (4) is held on the base surface (3, 15, 30, 36, 52) by a centrifugal acceleration generated by the rotational component. The invention is characterized in that a rotational movement is produced for at least some of the energy beam irradiating means (9, 22, 31, 38, 39, 55, 59, 61). Analogously, at least one energy beam rotational axis (46) is proposed for rotating at least some of the energy beam irradiating means (9, 22, 31, 38, 39, 55, 59, 61) in an additive manufacturing device in which the starting material (4) is held on a base surface (3, 15, 30, 36, 52) by a centrifugal acceleration.

摘要: The present disclosure relates to an apparatus for additively manufacturing a product in a layer-by-layer sequence, wherein the product is formed using powder particles deposited on an interface layer of a substrate. A laser generates first and second beam components. The second beam component has a higher power level and a shorter duration than the first beam component. A mask creates a 2D optical pattern in which only select portions of the second beam components can irradiate the powder particles. The first beam component heats the powder particles close to a melting point, where the particles experience surface tension forces relative to the interface layer. While the particles are heated, the second beam component further heats the particles and also melts the interface layer before the surface tension forces can act on and distort the particles, enabling the particles and the interface layer are able to bond together.

摘要: 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.

摘要: The present invention relates to a device as well as a method for creating three-dimensional structures consisting of a material to be consolidated, in particular a material containing organopolysiloxane, by way of locally selective consolidation of the latter as a result of light-induced organic cross-linking. The device is characterized by a movable focusing optical system for the formation of one or a plurality of laser foci, wherein either the laser beam of a laser source can be introduced into the material to be consolidated through the material container and a movable carrier unit is arranged in said container or the focusing optical system is immersed into the material bath and the laser beams can be introduced into the material to be consolidated via a beam exit area of the focusing optical system. In the method, a focusing optical system that is movable in at least one plane is used for the formation of at least one laser focus, and a movable carrier unit is positioned in the material to be consolidated in one embodiment.

摘要: Apparatus for additive manufacturing includes a light source that emits light into an optical path that extends to a powder bed or other platform for additive manufacturing. A phase modulator in the optical path is controlled to present a 2D pattern of phase shifts that steer the light to provide a desired pattern of optical power density on the powder bed. In some embodiments the optical path includes elements that focus the light into a small spot on the powder bed and a scanner operative to scan the spot over the powder bed. In some embodiments the light from the optical path is distributed over an area of the powder bed. A pattern of optical power density within the spot or area may be altered by changing the data controlling the phase modulator.
