摘要： An additive manufacturing system operates an extruder to extrude a swath of thermoplastic material through at least two nozzles of the extruder to form a swath of thermoplastic material along a path of relative movement between the extruder and a platform. The speed of the extruder along the path corresponds to a predetermined speed selected with reference to an orientation of the extruder and the angle for the path of relative movement between the extruder and the platform. A controller in the system operates at least one actuator operatively connected to at least one of the extruder and the platform to move the at least one of the extruder and the platform relative to the other of the extruder and the platform along the path of relative movement at the predetermined speed to make the swath of the thermoplastic material contiguous in a cross-process direction.

摘要： An extrusion assembly, a method of constructing an extrusion assembly, and an additive manufacturing system including an extrusion assembly are disclosed. The extrusion assembly includes an extrusion die; a channel having an inlet and an outlet, which is in fluid communication with the extrusion die; and a heating element that melts a filament material drive through the channel so that the melted material is extruded by the extrusion die. The heating element can be helically wound about the channel or extend parallel to the channel, among other configurations. Further, the extrusion assembly includes a temperature sensor that is positioned adjacent to the channel between the extrusion die and the heating element. The channel, heating element, and temperature sensor are enclosed together within a sheath as a single integral unit. An additive manufacturing system utilizing the extrusion assembly can include a drive assembly, a support assembly, and a controller.

摘要： An apparatus of manufacturing a rubber member includes an extruder; a mouthpiece; and a support surface which faces the mouthpiece in an opposed manner. The support surface and the mouthpiece are moved relative to each other thus molding a rubber member on the support surface. The apparatus further includes: a rubber pool portion formed between the mouthpiece and the support surface; and a closing surface having an inclined surface shape and capable of closing a moving-direction front side of the rubber pool portion. A rubber material is ejected from an ejection port in a state where the rubber pool portion is closed by the closing surface, the support surface and the mouthpiece are moved relative to each other after the rubber pool portion is filled with the rubber material, and a lamination starting end of the rubber material is pressed to the closing surface thus molding the lamination starting end into an inclined surface and, thereafter, the closing surface is moved in a direction away from the support surface.

摘要： A control device, method and device for applying at least one material to a substrate or a workpiece, an extruder, a 3D print head, a 3D printer and a machine tool, wherein the device includes a main body with an outlet for the materials, where the materials are fed through at least two access channels to the outlet and mixed and/or blended at this location, where a rotational movement of the main body with respect to the substrate or the workpiece causes the materials to blend in a manner analogous to a double helix or a plait such that mixing/blending of the materials is advantageously improved, and where if applied to a 3D printing process, then either the workpiece rotates about an axis of rotation that extends through the outlet of the main body, or the main body and consequently the outlet itself rotates.
