摘要： A mold includes a pair of first mold parts, a pair of second mold parts, and a pair of third mold parts that define six surfaces of a molded body substantially having a rectangular parallelepiped shape. At least one of the pair of third mold parts includes an upper mold part and a lower mold part. The upper mold part defines an upper space of a molding space, and the lower mold part defines a lower space of the molding space. The upper mold part and the lower mold part are individually slidable. The lower mold part protrudes toward the molding space with respect to the upper mold part so that a step portion is formed. The upper mold part is slidable in cooperation with the lower mold part in a state in which the step portion is formed or absent.

摘要： A system and corresponding method for additive manufacturing of a three-dimensional (3D) object to improve packing density of a powder bed used in the manufacturing process. The system and corresponding method enable higher density packing of the powder. Such higher density packing leads to better mechanical interlocking of particles, leading to lower sintering temperatures and reduced deformation of the 3D object during sintering. An embodiment of the system comprises means for adjusting a volume of a powder metered onto a top surface of the powder bed to produce an adjusted metered volume and means for spreading the adjusted metered volume to produce a smooth volume for forming a smooth layer of the powder with controlled packing density across the top surface of the powder bed. The controlled packing density enables uniform shrinkage, without warping, of the 3D object during sintering to produce higher quality 3D printed objects.

摘要： A metering apparatus and corresponding method meter a powder material in a three-dimensional (3D) printing system. The metering apparatus comprises a hopper with walls configured to contain a powder material, a metering roller, and a tool. The metering roller is located beneath an opening of the hopper. The metering roller and a given wall of the walls of the hopper are spaced apart by a gap therebetween at the opening; the gap in combination with rotation of the metering roller causes the powder material to flow from under the given wall of the hopper at a substantially predictable rate. The tool is positioned at the given wall where the flow emerges and is configured to force the powder material off of the metering roller to supply the 3D printing system with the powder material for printing a 3D object.
