Abstract: A method and system for tensioning film tank in a liquid photopolymer container designed for use in a stereolithography (SLA) additive fabrication device is disclosed. The liquid photopolymer container comprises a tank frame, a film clamp that attaches to the tank frame and secures a film between the clamp and the tank frame, and a film positioned between the clamp and the bottom surface of the tank frame. The film clamp and the tank frame include raised-features and recesses that mate together to increase the grip on the film.

Abstract: An improved additive fabrication device includes a build platform, a vessel designed to hold a liquid photopolymer, and an optical system featuring a micro-LED panel. The micro-LED panel, comprising multiple pixels, projects actinic energy toward the photopolymer in the vessel. The panel selectively activates pixels according to a mask pattern, enabling precise control over the fabrication process. This innovative device offers a streamlined approach to additive manufacturing, utilizing advanced optical technology for efficient and accurate production of complex structures.

Abstract: Techniques are described for calibrating an optical system in an additive fabrication device using an image of the build surface within the device. These techniques allow calibration to be performed by imaging one or more calibration features generated on (or at) the build surface, which may include illuminated regions of the build surface, regions of the build surface on which solid material has been formed, and/or regions of the build surface to which energy has otherwise been directed thereby making those regions distinguishable from their surroundings. The calibration features may be produced (at least in part) by the optical system to be calibrated. The location of the calibration features within the image may be compared with the intended location of these calibration features, and corrections to the optical system determined based on any differences between the actual and intended locations.

Abstract: In additive fabrication, less stiff layers generally require a comparatively higher peel force during separation, and that therefore geometric structures that include less stiff layers will also require a comparatively higher peel force during separation. Techniques to lower or otherwise mitigate undesirably large peel forces are described. These techniques include modification to how layers susceptible to a large peel force are formed, modification to a model of a part prior to generating instructions for an additive fabrication device to fabricate the part, and/or improvements to an additive fabrication device hardware.

Abstract: According to some aspects, techniques that address one or more drawbacks of laser-based optical systems in additive fabrication devices are described. In some aspects, an additive fabrication device may include one or more variable focus lenses that may be operated (e.g., actuated) during fabrication to adjust the focus, and thereby the spot size, of a laser beam. In some aspects, an additive fabrication device may comprise a laser array, such as a plurality of vertical-cavity surface-emitting lasers (VCSELs), that may be operated to direct light into a build region, rather than using a single laser beam, such as a single diode laser. In some aspects, an additive fabrication device may comprise a container that includes a flexible display film, such as a flexible LCD screen, which may be operated to direct light into the container to thereby cure a liquid photopolymer therein.
