A dynamic manufacturing system such as for the additive manufacture of a fabrication item with multiformative capabilities presents a processor (29) that can refine movement, instructions, or data to achieve greater manufacturing efficiency and substantially uninterruptive change between formative process elements (24) or capabilities with simple user input (28) or indications. Optimization of movements, deposition of material, positioning, variant repositioning for next item layers during fabrication are provided in manners where the functions can be self contained such as in a 3D printer or the like and can be accomplished without significant interruptions to traditional processing times or even in shorter times through the improved transformations.

A structural reinforcement for an article including a carrier that includes: (i) a mass of polymeric material having an outer surface; and (is) at least one consolidated fibrous insert having an outer surface and including at least one elongated fiber arrangement having a plurality of ordered fibers arranged in a predetermined manner. The fibrous insert is envisioned to adjoin the mass of the polymeric material in a predetermined location for carrying a predetermined load that is subjected upon the predetermined location (thereby effectively providing localized reinforcement to that predetermined location). The fibrous insert and the mass of polymeric material are of compatible materials, structures or both, for allowing the fibrous insert to be at least partially joined to the mass of the polymeric material. Disposed upon at least a portion of the carrier will be a mass of activatable material.

A molding apparatus includes: a die; a core disposed at the inner side of the die; a slider housed in a die recess provided in the die; a rod having a leading end portion housed in a slider recess formed in a face of the slider, the leading end portion of the rod being unconnected with the slider; and a movement mechanism, the die including a wall portion that forms part of an inner wall of the die recess, and the slider recess having a shape that widens on progression toward an outer side in a radial direction of the die or that runs along a radial direction of the die.

A liquefier assembly (20) for use in an additive manufacturing system (10) to print three-dimensional parts (22), which includes an upstream pressure-generating stage (52) and downstream flow-regulating stage (52). The upstream pressure-generating stage (52) includes a drive mechanism (46), a liquefier configured (52) to melt a consumable material (48) receive from the drive mechanism (46) to produce a molten material in a pressurized state. The downstream flow-regulating stage (52) includes a gear assembly (52) having a casing assembly (64,66,68) and a pair of gears (74,76) disposed within the interior cavity (78,80) and engaged with each other to regulate a flow of the pressurized molten material (48) through the gear assembly (52) for controlled extrusion.

To better control part quality of 3D printed parts, the temperature of an extruder filament using a secondary heat source is provided. A heat source, such as an infrared heat source, can be used to heat the filament of a 3D printer to the optimum temperature that will enhance welding of the filament to a substrate that it is being printed on or to. Such an optimum temperature can be based upon, in part, the temperature of the substrate. A controller or other intelligent control can be used to receive temperature readings of the substrate and/or filament and then can adjust the temperature of the heating source to optimize the temperature of the filament to better combine the filament to the substrate.

An injection molding machine for injecting a molten resin into a cavity of a molding die clamped in a die clamping unit via a nozzle formed in a heating cylinder to form a resin article includes a drive source. The drive source is configured to move the nozzle between a first position with the nozzle coupled to the molding die and a second position with the nozzle decoupled from the molding die. The drive source is also configured to pull out the molding die from the die clamping unit and to push the molding die into the die clamping unit.

An extrusion assembly may include an extrusion die and an extrusion tip at least partially positioned within the die. The extrusion tip may include a base portion having a tapered end and an opening positioned approximately at an apex of the tapered end. An insert may be adjustably positioned within the base portion and configured to extend through the opening to form a land. A length of the land may be variable as the position of the insert within the base portion is adjusted. Additionally, a length of an end portion of the extrusion die may be adjusted.

A polymeric insert formed by extruding a material including polyamide and a plurality of long fibers to form a column structure having a first profile. A method for making such an insert comprising passing a polymeric material in a substantially flowable state through a die, and substantially simultaneously passing a fiber through the die, wherein during the passing step the polymeric material has a relative viscosity of less than about 60 according to ASTM D789.

A manufacturing method of a middle frame for a display screen, a display screen and a display device is provided. The method includes: fixing a glass cover plate of the display screen to a first mold; bonding a second mold with the first mold, so as to form a cavity for forming the middle frame on a periphery of the glass cover plate; injecting a molten material into the cavity; cooling the molten material to form the middle frame, wherein the middle frame is integrally injected and molded on the periphery of the glass cover plate.
