摘要： A system for depositing a composite filler material into a channel of a composite structure includes an end-effector configured to extrude a bead of the filler material into the channel. The filler material can comprise a first group of relatively long fibers, a second group of relatively short fibers and a resin. A drive system is configured to move the end-effector relative to the channel, and a position sensor is configured to detect the position of the bead relative to the channel. A controller is configured to operate the drive system in response to the detected position and to operate the end-effector to heat and compress the filler material so as to orient the longer fibers in a substantially longitudinal direction relative to the channel and the shorter fibers in substantially random directions relative to the channel when the bead is extruded into the channel.

摘要： An insulated conduit for use in offshore, deep water environments includes a pipe and a fluoropolymer composition. The pipe has an outer surface with the fluoropolymer composition disposed about the outer surface of the pipe for providing a thermal insulation layer. The fluoropolymer composition includes a fluoroplastic polymer present in an amount of at least 50 parts by weight based on 100 parts by weight of the fluoropolymer composition. The fluoropolymer composition also includes a fluoroelastomer present in an amount of a fluoroelastomer present in an amount of from about 20 to about 50 parts by weight based on 100 parts by weight of the fluoropolymer composition. The fluoropolymer composition has a thermal conductivity less than about 0.20 W/mK at 205° C.

摘要： A technique for planarizing build surfaces in three-dimensional printing includes the use of a three-dimensional printer having an extruder with a sensor mechanically coupled thereto, where the sensor is operable to sense a contact force between the extruder and a separate structure. In particular, the sensor may be used to measure the contact force at a plurality of locations across a build surface of the separate structure, so that a difference between the measured contact force at two or more locations can be identified. In response to the difference between the measured contact force at these locations, a control signal may be created to reduce the difference for planarizing the build surface, e.g., by fabricating a layer on the build surface that mitigates irregularities therein, by gap filling on the build surface, or by adjusting a parameter of the three-dimensional printer.

摘要： An apparatus for depositing an extrudable substance comprises a bracket and a sleeve, comprising an inner tubular sleeve wall and an outer tubular sleeve wall. The sleeve is coupled to the bracket and is rotatable relative to the bracket. The apparatus also comprises a cartridge, comprising an inner tubular cartridge wall and an outer tubular cartridge wall. The cartridge is configured to be positioned between the inner tubular sleeve wall and the outer tubular sleeve wall. The apparatus also comprises a valve, configured to be communicatively coupled with the cartridge, a nozzle, configured to be communicatively coupled with the valve, a linear actuator to control flow of the extrudable substance from the valve to the nozzle, an annular plunger, positioned between the inner tubular cartridge wall and the outer tubular cartridge wall, and a push-lock pressure cap, configured to be hermetically coupled with the cartridge.

摘要： A method that combines injection molding and extrusion is disclosed. First, a molten material is injected into a mold via an injection gate, the mold comprising a first portion and a second portion. Next, additional molten material is injected via the injection gate and pushed through an extrusion die located in the first portion of the mold and the second portion is separated from the first portion. In embodiments, the second portion is separated from the first portion before the additional material is injected. In other embodiments, the second portion is separated from the first portion simultaneously with the additional material being injected. The method may be used to produce longer and thinner parts with detailed features, such as catheters.

摘要： A device for fabricating a continuous thermoplastic filament having a plurality of segments comprises first and second filament supply components for supplying first and second thermoplastic filaments and a filament cutting component for cutting each of the first and second thermoplastic filaments into segments. The device also includes first and second filament guide components for guiding the first and second thermoplastic filaments into position to be cut by the filament cutting component. The device further includes a filament segment joining section positioned after the filament cutting component to join the first and second thermoplastic filaments to form a continuous thermoplastic filament having a plurality of segments. The first and second filament guide components are movable so as to alternatively and sequentially permit the first and second thermoplastic filaments to be cut by the filament cutting component.

摘要： A device is described where an operator uses a handheld nozzle that deposits new material onto a part. The process can be used to create new parts from a substrate, or to repair parts. The device automatically maps the physical part and matches the physical part against a model of the desired part. As the operator moves the nozzle over the part, the device automatically computes the amount of material necessary to modify the current part to match the model of the desired part. This method can be used for spraying or spray-casting metal, ceramics, and other materials. The described process and device automates this process, and simplifies the operator's involvement. Moreover, because the device can measure the part as the material is being deposited, the resulting part is more likely to more closely resemble the original part both in aesthetics and physical properties.
