摘要： A three dimensional printing system (2) for producing a three dimensional article of manufacture includes a build platform (6), a powder dispensing apparatus (14), a light emitting device head (26), a drop ejecting head (24), a movement mechanism (12), and a controller (16). The light emitting device head may be a vertical cavity surface-emitting laser (VCSEL) head that has a columnar arrangement of VCSELs that emit light having a defined spectral distribution. The drop ejecting head is configured to separately eject a plurality of different inks having correspondingly different absorption coefficients for the defined spectral distribution. The controller operates the powder dispensing apparatus to dispense powder, move and operate the drop ejecting head to define an array of inked pixels, and move and operate the VCSEL head to fuse the inked pixels. The controller varies an energy output of the VCSELs in correspondence with a variation of an absorption coefficient of the inked pixels.

摘要： A three dimensional printing system (2) is configured to form a three dimensional article of manufacture (12) through a layer-by-layer process. The layers are formed by selectively adding photocure resin (6) onto a lower face (24) of the three dimensional article of manufacture. The three dimensional printing system includes a plurality of light engines (30) that are configured to define a corresponding plurality of build fields (31) in the resin. The plurality of build fields define one or more overlap zones (32). The plurality of light engines are configured to define extended threshold zones (34A, 34B) within the overlap zones that correspond to light engine edge defects and artifacts. A light engine applies a transparency value of less than a specified threshold over an extended threshold zone proximate to an edge of the build field corresponding to the light engine.

摘要： A three dimensional printer includes a vessel, a light engine, a fixture, a movement mechanism, a sensor, and a controller. The vessel is for containing a liquid photocurable resin and includes a transparent sheet defining a lower surface through which the resin can be illuminated. The light engine is disposed and configured to selectively illuminate the resin through the transparent sheet. The fixture is for supporting a three dimensional article of manufacture having a lower face immersed in the resin in facing relation with the transparent sheet. The movement mechanism is configured for controllably translating the fixture to adjust a vertical height of the lower face above the transparent sheet. The sensor is configured to monitor a dynamic vertical drag force of the resin upon the three dimensional article of manufacture.

摘要： Methods and apparatus are provided for controlling the temperature of powders in a powder-based additive manufacturing system using spatial light modulation. Powder layer temperatures can be measured and selectively controlled using a radiation source comprising a spatial light modulator. The spatial light modulator applies a visible light radiation and/or IR radiation. In addition to controlling the pre-fused temperature of the powder in the image plane, the spatial light modulator can also apply the radiation to fuse the powder.

摘要： There is provided an additive manufacturing system (10) comprising a vertical stage (12) (also known as a z-stage) that moves the object (14) 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 (16), upon which the additively manufactured object (14) 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 (10) is capable of making larger objects, shortening build times, improving part resolution, and/or reducing the volume of photocurable material needed, among other benefits.

摘要： 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.
