摘要： Various embodiments related to three dimensional printers, and reinforced filaments, and their methods of use are described. In one embodiment, a void free reinforced filament is fed into an conduit nozzle. The reinforced filament includes a core, which may be continuous or semi-continuous, and a matrix material surrounding the core. The reinforced filament is heated to a temperature greater than a melting temperature of the matrix material and less than a melting temperature of the core prior to drag the filament from the conduit nozzle.

摘要： A method for material handling and mold filling is provided which directs the flow of molten plastic material from an extruder and allocates the molten material to a plurality of nozzles through the use of independently operated, variable valves. The method therefore provides independent streams of molten plastic material having variable temperatures and flow rates or volumes to particular sections or regions of the mold. This independent temperature or flow of molten plastic material facilitates the complete, rapid and accurate filling of the molds, reducing turbulence and other temperature or flow-related imperfections in the finished components. A method of using a multiphase material handling system is also disclosed for expeditious sequential and simultaneous filling and pressing of the mold and extracting the completed component from the system.

摘要： A pendulum device includes a base. A rotating plate is pivoted on the base. A movable member is eccentrically pivoted on the rotating plate by one of two ends thereof, and the other end of the movable member is for connecting to an article to be operated. A driving unit is at one side of the base. The driving unit is for driving the rotating plate of the base to perform a uniform circular motion. Because of the movable member eccentrically pivoted on the rotating plate, when the operating end is connected to the article, the operating end is dragged by the transmission of the rotating plate to perform a simple harmonic motion that is a variable accelerating linear motion relative to the rotating plate.

摘要： An additive manufacturing system may include a head configured to discharge a matrix-coated reinforcement, a support configured to move the head during discharging, and a cure enhancer configured to cure the matrix as the matrix-coated reinforcement discharges from the head. The additive manufacturing system may also include a controller in communication with the head, the support, and the cure enhancer. The controller may be configured to receive specifications for a structure to be fabricated, and to determine an anchor point from which the matrix-coated reinforcement will be pulled during fabrication of the structure. The controller may also be configured to regulate operation of the head, the support, and the cure enhancer to manufacture the structure and the anchor point.

摘要： Disclosed is an improved extruder head for a fused filament fabrication 3D printer. It would be beneficial with a thinner nozzle diameter and higher extrusion speed without slippage in the feeding mechanism. The proposed improved extruder head enables extrusion of thinner extruded material at a higher extrusion speed without any slippage in filament feeding mechanism, thereby allowing higher overall building speed of the 3D printer with high quality build. Higher feed-rate of the filament material is achieved by increased usable friction between pinch wheel and filament by increasing the grippable area of the filament. This is done by feeding the filament into the feeding mechanism at an angle different to the outlet angle and routing it around the pinch wheel, back supported by a plurality of support rollers, so that the filament is in frictional contact with the pinch wheel along a greater part of its circumference, thereby increasing the surface contact area between the pinch wheel and the filament. Owing to non-slippage of the filament feeder, nominal volume of extruded material is exactly the same as desired volume with high filament feeding rate. Due to compact feeding mechanism, total mass of extruder kept small enough to enable higher acceleration of the printing nozzle resulting higher printing speed. Owing to horizontal loading of the filament material, feed roll can be mounted just above the extruder for smooth filament supply and compact size of 3D printer.

摘要： A head assembly for an extrusion-based 3D printer includes: a fluid-dispensing head having a manifold and at least two fluid-dispensing nozzles, of different sizes, which are mounted in communication with a melt chamber in a manifold. Outlets of each nozzle are closed by respective valve members. A rocker serves both to pivot the nozzles to their lowermost nozzle-operating position and to actuate the valve members, for ready switching between the valves, such that the smaller nozzle can be used for high resolution work, and the larger nozzle can be used for bulk infill.
