Abstract: An additive manufacturing system has a powder delivery system for presenting a powder material to a build chamber. A laser selectively sinters the powder material in the build chamber. The build chamber is presented in an annular configuration with the powder delivery system and laser arranged within a central portion thereof.

Abstract: Stiffeners are disclosed which can be added to the header section of cast light-metal door panels. The header section casting can be designed for manufacturability, and to meet nominal lateral stiffness specifications while making effective use of material. The stiffeners can be cast in place in the header or attached to the header section after casting via snap-fit features, adhesive or both. The stiffeners can themselves be made of a light-weight metal such as aluminum, and can be produced by roll forming, stamping or extrusion. By effectively yielding a closed-section door header shape, the stiffeners provide maximum incremental bending stiffness in the header while adding a minimum amount of incremental material and mass.

Abstract translation: 公开了加强件，其可以添加到铸造轻金属门板的头部。 头部铸件可以设计成可制造性，并且在有效地使用材料的同时满足标称横向刚度规格。 加强件可以在通过卡扣配合特征，粘合剂或两者浇铸之后，在集管中浇注或附接到集管部分上。 加强件本身可以由诸如铝的轻质金属制成，并且可以通过辊压成形，冲压或挤出来制造。 通过有效地产生闭式门头形状，加强件在集管中提供最大的增量弯曲刚度，同时增加最小量的增量材料和质量。
