Abstract: A tire change tool comprising a generally circular and planar faceplate having a hub side and a user side, the hub side and user side being generally parallel; an upper elbow flexibly connected to the faceplate by an interface; an arm connected to the upper elbow at a first end, and connected to a lower elbow at a lower end; and a footplate flexibly connected to the lower end of the arm by the lower elbow, wherein the faceplate and the interface comprise co-aligned apertures, the co-aligned apertures having an axis perpendicular to the plane of the faceplate. A length adjustment mechanism may be incorporated into the arm and adapted to permit the arm's length to be changed. The arm may include an upper section and a lower section adjustable connected by an adjustment mechanism adapted to permit the arm's length to be changed.

Abstract: Disclosed are systems, devices, and methods for additive manufacturing that allow for control of composition and/or porosity of components being manufactured. More particularly, in exemplary embodiments, a secondary material can be used in conjunction with a primary feedstock material in a spatially controlled manner during an additive manufacturing process to control a composition of materials and/or porosity of a manufactured component. Systems, devices, and methods for additive manufacturing are also disclosed that allow for control of a pressure of an atmosphere surrounding a build surface during an additive manufacturing process. More particularly, a pressure of an atmosphere surrounding a build surface can be raised to a pressure greater than standard atmospheric pressure. Various features of the exemplary embodiments of the systems, devices, and methods disclosed can be used together to further control for composition and/or porosity and quality of a manufactured part.
