Systems and methods for manufacturing a product include a mixing station for preparing a solution containing a base material and a performance modifier. The base material is configured to deliver performance characteristics of the product that are preselected and the performance modifier is configured to enhance the performance characteristics. An encapsulation station produces particles of the performance modifier in a coating of the base material as an encapsulate powder. An additive manufacturing cell includes an energy source and is used to build the product from the encapsulate powder by an application of energy from the energy source.

Products and methods are provided for additive manufacturing of products in a collapsed state for post printing expansion in preparation for use in their intended application. A product includes interconnecting members configured for forming by printing in a collapsed state, with joints between the interconnecting members configured for relative movement of the interconnected members from the collapsed state to an expanded state. The interconnecting members define a larger package size in the expanded state than in the collapsed state. The joints are freely moveable in the collapsed state and are locked in place in the expanded state.

Additive manufactured grille and method

A method of forming an additive manufactured component comprises depositing a first layer of build material on a build platform within an additive manufacturing machine, depositing reinforcement fibers into the first layer of build material, orienting the reinforcement fibers within the first layer of build material, lowering the build platform, depositing a second layer of build material on top of the first layer of build material, depositing reinforcement fibers into the second layer of build material, and orienting the reinforcement fibers within the second layer of build material.

Controlled fiber orientation in additive manufactured parts

An additive manufacturing method comprises: positioning a sheet of composite material; curing a predetermined portion of the sheet; cutting the sheet about the perimeter of the predetermined portion to create a preceding processed sheet; adding a successive sheet of composite material atop and in contact with the preceding processed sheet; curing a predetermined portion of the successive sheet such that the predetermined portions of the successive sheet and the preceding processed sheet are bonded together; and cutting the successive sheet about the perimeter of its predetermined portion to create a subsequent processed sheet. The steps of adding, curing and cutting a successive sheet may be repeated for a plurality of cycles to produce a three-dimensional composite product.

A structural instrument panel member for an instrument panel assembly of a vehicle comprises a cross beam, a steering column support, a first and second HVAC duct, and a first dash panel mount. The cross beam mount has a first surface, a first side, a second side and a first, second, third, fourth and fifth walls. The cross beam mount is fastened to a cross beam of the vehicle. The steering column support extends from the first side of the cross beam mount. The first and second HVAC duct each have a first end and a second end. The first HVAC duct is disposed on the second side of the cross beam mount and the second HVAC duct is disposed adjacent the first HVAC duct. The first dash panel mount extends from the first HVAC duct and fastened to a dash panel of the vehicle.

HVAC instrument panel bracket

A method of manufacturing a structural support member, the method includes providing a donor casting, separating the donor casting into at least a first segment and a second segment, providing a mold, disposing the first and second segments into the mold, pouring a liquid metal alloy into the mold. recovering and cleaning a solidified structural support member from the mold, and performing an operation for achieving a mechanical lock feature between the first and second segments and the solidified metal alloy.

Method of manufacturing structural components

An automotive structural component includes a lattice structure. The lattice structure defines a plurality of cells. The plurality of cells include a multitude of at least partially filled cells each at least partially filled with a filling, and a multitude of hollow cells distributed amongst the multitude of at least partially filled cells to distribute and direct load.

Automotive structural component and method of manufacture

A system and method for fabricating a vehicle structure includes a first portion and a second portion having a body cooperating with the first portion using an additive manufacturing process. The body of the second portion includes one or more projections extending from the body. A third portion includes at least one opening and operatively engages the one or more projections of the second portion.
