摘要： Implementations described herein are directed to forming objects including one or more layers of a polymeric material that include a magnetic material. The objects can be produced by forming one or more first layers that include a first polymeric material. The one or more first layers can be free of a magnetic material. Additionally, the object can be produced by forming one or more second layers that include a second polymeric material having a magnetic material. For example, the one or more second layers can include a polymeric material embedded with magnetic particles. The one or more first layers and the one or more second layers can be formed by extruding the first polymeric material and the second polymeric material onto a substrate according to a pattern. A magnetizing device can be used to magnetize the magnetic material included in the one or more second layers.

摘要： An extrusion head or other similar tool head of a three-dimensional printer is slidably mounted along a feedpath of build material so that the extruder can move into and out of contact with a build surface according to whether build material is being extruded. The extrusion head may be spring-biased forward along a feedpath to rest in a downward position, or the extrusion head may be spring-biased against the forward feedpath so that the extruder remains above the build surface in the absence of applied forces, and then moves downward into a position for extrusion when build material is fed into the extruder.

摘要： A system for additively manufacturing a composite part comprises a delivery guide, movable relative to a surface. The delivery guide is configured to deposit at least a segment of a continuous flexible line along a print path. The continuous flexible line comprises a non-resin component and a thermosetting-resin component. The thermosetting-resin component comprises a first part and a second part. The non-resin component comprises a first element and a second element. The system further comprises a first resin-part applicator, configured to apply the first part to the first element, and a second resin-part applicator, configured to apply the second part to the second element. The system also comprises a feed mechanism, configured to pull the first element through the first resin-part applicator, to pull the second element through the second resin-part applicator, and to push the continuous flexible line out of the delivery guide.

摘要： Hollow fiber membranes having improved toughness and durability are prepared using a vinylidene fluoride polymer-containing component, such as Kynaro resins, having relatively low crystallinity. One aspect of the invention provides a membrane in the form of a fiber, wherein i) the fiber has a porous wall of a polymeric component enclosing a central hollow space extending the length of the fiber, ii) the polymeric component has a crystallinity as determined by wide angle x-ray diffraction of less than about 35%, iii) the polymeric component is comprised of at least one homopolymer or copolymer of vinylidene fluoride and iv) the membrane has an energy to break of at least about 0.5 J per square mm of membrane cross section.

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： A printer system may include a coaxial extruder head that extrudes a core, a bulk, and/or a core and bulk cladding to form complex structures without retooling. The coaxial extruder head may include a distribution channel with an entrance and an exit, a priming chamber that surrounds the distribution channel. The priming chamber may include an outlet and a first inlet, a heating element thermally connected to the priming chamber, and a nozzle connected to the outlet of the priming chamber. Further, the nozzle may converge from the outlet of the priming chamber to an orifice of the nozzle. In addition, the exit of the distribution channel may be disposed at the orifice of the nozzle. This structure facilitates extruding a core and cladding type composite from the extruder head.
