CORE-SHELL MORPHOLOGY OF COMPOSITE FILAMENTS FOR USE IN EXTRUSION-BASED ADDITIVE MANUFACTURING SYSTEMS
A consumable filament for use in an extrusion-based additive manufacturing system, where the consumable filament comprises a core portion of a matrix of a first base polymer and particles dispersed within the matrix, and a shell portion comprising a same or a different base polymer. The consumable filament is configured to be melted and extruded to form roads of a plurality of solidified layers of a three-dimensional part, and where the roads at least partially retain cross-sectional profiles corresponding to the core portion and the shell portion of the consumable filament and retain the particles within the roads of the printed part and do not penetrate the outer surface of the shell portion.
ADDITIVE MANUFACTURING APPARATUS AND ADDITIVE MANUFACTURING METHOD
An additive manufacturing apparatus includes a discharging unit that discharges resin powder into a molding tank; a supplying unit that supplies a fiber into the molding tank; and a solidifying unit that solidifies at least part of a resin layer including the fiber and formed in the molding tank.
Coextrusion feedblock, coextrusion profiling insert assembly, and methods of operation
The invention provides a coextrusion feedblock having a flow adjuster, a viscosity compensation device, an actuator, a central extrusion conduit, and a coextrusion conduit. The invention also provides a coextrusion profiling insert assembly constructed to be mounted in a coextrusion feedblock. The insert assembly has a flow adjuster, a viscosity compensation device, and an actuator. The insert assembly when mounted in the feedblock has a coextrusion conduit extending between the flow adjuster and the viscosity compensation device. The actuator is adjustable to apply force to bend the viscosity compensation device and thereby adjust a gap height of the coextrusion conduit. Also provided is a method of operating a feedblock having a viscosity compensation device comprising a flex region, a central extrusion conduit, and a coextrusion conduit. Force is applied to bend the flex region of the viscosity compensation device and thereby adjust a gap height of the coextrusion conduit.
Vehicle rear slider window assembly with upper rail co-extruded filler
A slider window assembly for a vehicle includes at least one fixed window panel and a movable window panel that is movable along an upper rail and a lower rail at the at least one fixed window panel between a closed position and an opened position. The upper rail includes a channel, and a filler is disposed in the channel of the upper rail. The filler includes a filler body having opposite side walls, and the filler includes lips established along respective ones of the side walls. The lips are extruded onto and along the filler body. The lips include a compressible and flexible material and provide a dampening and cushioning function at the movable window panel when the movable window panel is disposed in the channel of the upper rail.
