Patent number: 11465343Abstract: A method of manufacturing continuous fiber reinforced thermoplastic components includes receiving, by a movable die, spread dry fiber tows. The method also includes receiving, by the movable die and from a polymer extruder fluidically coupled to the movable die, molten polymer. The method also include wetting, by the movable die, the spread fiber tows with the molten polymer. The method also includes maintaining, by the movable die, the wet fiber tows spread as the wet fiber tows exit the die. The method also includes depositing, by the movable die, a layer of the wet fiber tows on a printing surface. The movable die is configured to move along the printing surface to form a thermoplastic component of one or more layers of fiber tows on the printing surface.Type: GrantFiled: December 17, 2019Date of Patent: October 11, 2022Assignee: Saudi Arabian Oil CompanyInventors: Abderrahim Fakiri, Abdullatif Jazzar

Patent number: 11455073Abstract: A computer-based system and method generate a movement of a 3D part of a 3D assembly in a 3D scene. Movement of the 3D part represents rotation by a predetermined angle. The method a) displays a 3D assembly of 3D parts in the 3D scene; b) selects a 3D part of the 3D assembly; and c) displays in the 3D scene a 3D manipulator. The 3D manipulator comprises three axes, and is anchored to the 3D part at an anchor point. The method then d) drags the 3D manipulator along one axis by a current distance from the anchor point on the axis. The predetermined angle corresponds to a maximum distance from the anchor point. The method e) while dragging the 3D manipulator, computes a ratio of the current distance to the maximum distance, and f) generates the movement of the 3D part proportionally to the ratio.Type: GrantFiled: August 15, 2019Date of Patent: September 27, 2022Assignee: Dassault SystemesInventors: Christophe Rene Francis Delfino, Guillaume Romain Dayde

Patent number: 11449647Abstract: A method and system provide the ability to generate models. A generative shelled base is created as a hollow computer-aided design (CAD) design. A t-spline mid-surface shell is created from the generative shelled base, which is then used to create a shell mesh model. A t-spline solid body is created from the generative shelled base, which is used to create an internal support structure that is converted into a shell CAD geometry, which is used to create a support structure mid-surface shell. The support structure mid-surface shell is combined with the shell mesh model into a generative mid-surface mesh that is used in a computer-aided engineering (CAE) crash simulation. The generated shelled base is combined with the shell CAD geometry into a generative shelled solid that is utilized in an additive build simulation.Type: GrantFiled: January 21, 2020Date of Patent: September 20, 2022Assignee: AUTODESK, INC.Inventors: Michael Grau, Andrew John Harris

Patent number: 11433482Abstract: An additive manufacturing apparatus forms layers with a material that is molten to produce a formed object. The additive manufacturing apparatus includes a CMT power supply that supplies as a power supply current to heat a wire that is the material fed to a workpiece, to the material; a laser oscillator that produces as a beam source a laser beam that is a beam with which the workpiece is irradiated; and a head drive unit that shifts as a drive unit a feed position for the material on the workpiece and an irradiation position for the beam on the workpiece. The additive manufacturing apparatus shifts the feed position and the irradiation position, with the irradiation position leading in a moving path for the feed position in spaced relation to the feed position.Type: GrantFiled: July 8, 2019Date of Patent: September 6, 2022Assignee: MITSUBISHI ELECTRIC CORPORATIONInventor: Takafumi Fujii
