  • Patent number: 8794263
    Abstract: A filter assembly for an additive manufacturing apparatus has a housing defining a gas inlet and a gas outlet. A filter element is located within the housing between the gas inlet and the gas outlet. The assembly includes valves that can be actuated to seal the gas inlet and the gas outlet. Additionally the assembly has a fluid inlet for allowing ingress of a fluid into the housing. The assembly allows a filter element, which may contain volatile particles, to be changed safely. By sealing the gas inlet and outlet and flooding the housing with a suitable fluid, volatile particles captured by the filter can be neutralised.

  • Publication number: 20140163717
    Abstract: Scanning Laser Epitaxy (SLE) is a layer-by-layer additive manufacturing process that allows for the fabrication of three-dimensional objects with specified microstructure through the controlled melting and re-solidification of a metal powders placed atop a base substrate. SLE can be used to repair single crystal (SX) turbine airfoils, for example, as well as the manufacture functionally graded turbine components. The SLE process is capable of creating equiaxed, directionally solidified, and SX structures. Real-time feedback control schemes based upon an offline model can be used both to create specified defect free microstructures and to improve the repeatability of the process. Control schemes can be used based upon temperature data feedback provided at high frame rate by a thermal imaging camera as well as a melt-pool viewing video microscope. A real-time control scheme can deliver the capability of creating engine ready net shape turbine components from raw powder material.

    Abstract: A three-dimensional printer is configured to fill interior cavities of a fabricated object with functional or aesthetic materials during fabrication. In general, a number of layers can be fabricated with an infill pattern that leaves void space within an exterior surface of the object. These void spaces can receive a second material such as an epoxy or adhesive that spans multiple layers of the object to increase structural integrity. Similarly, aesthetic materials may be used to add color, opacity or other desired properties to a fabricated object. The void spaces can also or instead form molds that are filled with a build material to provide a fabricated object.

  • Patent number: 8412588
    Abstract: Systems and methods are provided for fabricating products on demand. In some embodiments, a manufacturable model, which may include information about a three-dimensional representation of a product to be fabricated, is received by a user of an electronic system and may be validated by the electronic system. A prototype of the product can be generated based at least in part on the manufacturable model, and the manufacturable model and/or the product can be made available for selection by other users of the system. The product may be fabricated based at least in part on the manufacturable model using, for example, a three-dimensional printer, and may be delivered to users of the electronic system.

  • Publication number: 20130073073
    Abstract: A conveyor or other transport mechanism is provided to support multiple, sequential builds from a three-dimensional fabrication machine. The conveyor may be heated/cooled, coated, or otherwise treated to assist in adhesion during a build, as well as removal of objects after a build. Each fabricated object may be automatically removed from the conveyor as the conveyor moves in order to restore a buildable surface for fabrication of additional objects.

  • Patent number: 8374714
    Abstract: The systems and methods disclosed herein employ a combination of digital three-dimensional modeling and rapid fabrication technologies to provide pre-indexed, pre-registered, and/or precut components for articulated dental models. Dental articulators and components of dental models as described herein use a positioning key to encode positional information for components of the dental model, and/or a reference grid on mounting surfaces to enforce local accuracy of fabricated parts against a fixed reference array.

  • Patent number: 8364301
    Abstract: A method is set forth for making a computer model of patient's jaws on the basis of digital information. Digital data about the jaws, teeth, soft tissues and artificial teeth is joined in computer space to create aesthetic and functional plans for the removal of teeth, shaping of supporting bone and placement of dental implants. Artificial teeth and pre-manufactured prosthetic devices are made and attached to the dental implants at the time of surgery. The aesthetic and functional position of artificial teeth is determined prior to surgical removal of natural teeth and the ideal position of implants and the proper form of the remaining bone are determined prior to surgery. Surgical guides used to shape bone, record occlusal orientation and position dental implants are manufactured using computer milling or layered manufacturing.

  • Patent number: 8359118
    Abstract: A method of producing a flexible vessel model for simulating a surgical operation, which is a three-dimensional model being capable of reproducing an aneurysm or narrowing occurring in the artery or vein based on CT/MRI image data of a patient obtained in practice and thus allowing vascular therapy trainings and preoperative simulations, with the use of a precise lamination modeling machine, wherein a vascular model having an affected part is fabricated by using a lamination technique together with a supporting material for sustaining the shape of the three-dimensional model during the fabrication in the precise lamination modeling machine and, after the completion of the fabrication by the lamination machine technique, the supporting material is removed.

  • Patent number: 8355810
    Abstract: A method and system for estimating context offsets for run-to-run control in a semiconductor fabrication facility is described. In one embodiment, contexts associated with a process are identified. The process has one or more threads, and each thread involves one or more contexts. A set of input-output equations describing the process is defined. Each input-output equation corresponds to a thread and includes a thread offset expressed as a summation of individual context offsets. A state-space model is created that describes an evolution of the process using the set of input-output equations. The state-space model allows to estimate individual context offsets.

  • Patent number: 8352089
    Abstract: A network of fluid dispensers is configured such that a Host controller may exchange information with local dispensers, and where local dispensers may exchange information with each other. The information may be dispensing processes, information regarding quality and reliability, problems and/or helpful information, and applications. The information may be exchanged in real time during fluid dispensing where any issues may be shared and resolved quickly even in remote locales. The applications may be developed at a local dispenser or at the Host and then shared throughout the network. The operating systems may include application software development tools, and the applications may include: monitoring deliver schedules and materials inventories; automatic issuing of purchase orders; training broadcasts; implementing industry standards for validation and approval.

  • Patent number: 8347240
    Abstract: A mechanism is provided for converting a set of single-layer design rules into a set of split-layer design rules for double patterning lithography (DPL). The set of single-layer design rules and minimum lithographic resolution pitch constraints for single exposure are identified. The set of single-layer design rules comprise a first plurality of minimum distances that are required by a set of first shapes in a single-layer design. Each of the first plurality of minimum distances in the set of single-layer design rules are modified with regard to the minimum lithographic resolution pitch constraints for single exposure, thereby forming the set of split-layer design rules. The set of split-layer design rules comprise a second plurality of minimum distances that are required by a set of second shapes and a set of third shapes in a split-layer design. The set of split-layer design rules are then coded into a design rule checker.
