Abstract: A support fixture is provided for forming a three dimensional article of manufacture onto a lower build surface thereof. The formation occurs in a resin vessel containing photocurable resin. The resin vessel includes a transparent sheet that forms a lower bound for the resin. The support fixture includes a lower planar portion, an upper portion, and a side wall coupling the lower planar portion to the upper portion. The lower planar portion defines a dense array of small openings that minimize a fluid drag of lateral resin motion when the lower build surface is proximate to the transparent sheet. The upper portion is for providing alignment and support within the three dimensional printing system. A plurality of large openings formed along the side wall that individually have a cross sectional area that is equal to a combined cross sectional area of a plurality of the small openings.

Abstract: There is provided an additive manufacturing system comprising a vertical stage (also known as a z-stage) that moves the object being created along an axis of motion that is not perpendicular to the image plane (non-parallel to the z-axis of the image plane). By moving the build platform, upon which the additively manufactured object is being supported, along a predetermined axis of motion, such as one adapted to the dominant axis of the object design, the additive manufacturing system is capable of making larger objects, shortening build times, improving part resolution, and/or reducing the volume of photocurable material needed, among other benefits.

Abstract: A socket for a prosthetic limb is created by making a cast of a residual limb. Marks can be applied to the interior surface of the cast to indicate the locations of anatomical features of the residual limb. The marked interior surface can be scanned and the scan data can be sent to a master fabrication center. The scan data can be modified and a master can be produced from the modified scan data. The socket can then be formed from the plastic material on the master.

Abstract: A method for creating tubular inserts is useful for creating custom fitted inserts that correspond to the anatomy of a patient and solve the problem of pressure points, wear of the implant, damage to surrounding tissue, and denting. Surface measurements of the affected portion of a patient's internal cavity are obtained. Those measurements are used to design a core. The core is 3D printed with a soluble material. The core is wrapped with a thin filament or film such that the contours from the core develop on the outer surface of the covering. The covering is hardened and the core is dissolved away, leaving a custom-made implant device that can be deposited in the patient's cavity.

Abstract: A three dimensional (3D) printer generates 3D articles of manufacture through the selective hardening of light curable liquid resins. The 3D printer includes a vessel, a fixture, a movement mechanism, a light engine, a controllable pressure source, and a controller. The vessel contains light curable resin with a bottom portion including a transparent sheet. The light engine selectively illuminates a lower face of a 3D article of manufacture being formed through the transparent sheet. The fixture and movement mechanism selectively translate the lower face up and down which generates a varying pressure of the resin against a top surface of the transparent sheet. The controllable pressure source applies a gas pressure to a bottom surface of the transparent sheet to offset the varying pressure of the resin.

Abstract: A three dimensional printing system includes a plurality of light engines, an alignment article, a camera, and a controller. The plurality of light engines define a corresponding plurality of build fields which overlap and define a build plane. The alignment article carries an alignment calibration image and is configured to be mounted in the three dimensional printing system with the alignment calibration image proximate to the build plane and in facing relation with the plurality of light engines. The alignment calibration image defines a dark field with an array of reflective alignment targets. The camera is mounted to be in facing relation to the alignment calibration image. The controller is configured to operate at least the light engines and the camera to individually align the light engines to the alignment calibration image.

Abstract: A three dimensional printing system includes a vertical support, a support plate, a resin vessel, a fluid spill containment vessel, and a light engine. The support plate is affixed to the vertical support at a proximal end. The support plate has an inner surface defining a first central opening. The resin vessel is supported above the support plate and has an inner edges surrounding a second central opening. The resin vessel includes a transparent sheet that closes the second central opening. The fluid spill containment vessel is supported below the support plate and includes a transparent window. The light engine is supported below the fluid spill containment vessel. The first central opening, the second central opening, and the window laterally overlap to provide an optical path whereby the light engine can project light upwardly to a build plane in the resin vessel.

Abstract: The invention relates to an apparatus for layered manufacture of a three-dimensional product, in particular for application of an additive manufacturing technique such as selective laser melting. This apparatus has a build chamber in which said product is constructed and an optical system that extends outside of the build chamber. The optical system has at least a beam source to generate an energy beam and contains corresponding scanning means to move this beam. Here, a control unit is provided that controls the scanning means to move the beam so that it strikes a selected position. The wall of the build chamber features a closed window that is transparent for the beam so that it passes through the window and enters the build chamber.
