A lamination molding apparatus includes: a material layer forming device that forms a material layer in a molding region; an irradiator that sinters or melts the material layer to form a solidified layer; and a cooling device that cools, to a cooling temperature, at least a part including an upper surface of a solidified body. The material layer forming device includes: a base having the molding region, a recoater head disposed on the base, a recoater head driving device that reciprocates the recoater head in a horizontal direction, and a blade that is arranged on the recoater head and that levels material powder to form the material layer. The cooling device includes: a cooling body that is controlled to the cooling temperature and comes into contact with the upper surface of the solidified body, and a mounting member that mounts the cooling body to the recoater head.
A food heating apparatus includes a main tank, a water exhaust tank, reserve tanks, communication chambers, heat insulating partition walls, a water exhaust tank and pressure exhaust pipes. The main tank stores water exceeding 100° C. The reserve tanks communicate with the main tank and imparts hydraulic head pressure to the water in the main tank. The communication chambers are respectively between the main tank and the reserve tank and have top plates higher than a top plate of the main tank. The heat insulating partition walls separate the main tank and each reserve tank and protrude into the front communication chamber. The water exhaust tank higher than the communication chambers has an upper surface higher than water surfaces of the reserve tanks. The pressure exhaust pipes have inlet openings in the top plates of the communication chambers and outlet openings within the water exhaust tank higher than the water surfaces.

METAL POWDER LAMINATION MOLDING METHODS AND METAL POWDER LAMINATION MOLDING APPARATUS
A work piece is damaged by a power failure or the like. Provided is a metal powder lamination apparatus, in which a control apparatus detects a load received by a blade while moving a recoater head along a B axis, stops the recoater head when the blade receives a load greater than or equal to a predetermined value, stores the position and height of an obstructive protrusion in a storage apparatus, repeatedly lowers a molding table by a predetermined height, and removes by planing only the largest obstructive protrusion among multiple obstructive protrusions after the recoater head moves to the end.
An electric discharge machining unit capable of stably supplying working fluid to the vicinity of a portion to be machined. The electric discharge machining unit includes a tool electrode, a housing, an electrode guide, and a working fluid supplying device. The housing includes a fitting hole having a tapered surface. A first supply path is formed in the housing. The electrode guide includes a tapered portion and an ejection opening formed on a lower surface. A first flow path is formed in the electrode guide. The tapered portion is configured to be fitted into the fitting hole to connect the first flow path to the first supply path. The working fluid supplied from the working fluid supplying device to the first supply path and the first flow path is ejected from the ejection opening.
Provided is a method for manufacturing material powder for metal laminating modelling, in which a virgin material is manufactured based on the particle size distribution of the virgin material being an unused material powder, and the fluidity of an unsintered reused material after the virgin material is reused a predetermined number of times by a metal laminating modelling device, so that the particle size distribution of the virgin material corresponds to the fluidity of the reused material that is equal to or greater than a predetermined standard value. Silica particles may be added to the virgin material.
