摘要： In a reaction apparatus, a reaction furnace is cylindrical and includes a supply port for receiving a raw material to be supplied at one end and a discharge port for discharging a reaction product at another end. A temperature control region includes an apparatus for controlling a temperature of the reaction furnace. A screw extends from the one end of the reaction furnace to the other end and is configured to be able to convey the raw material toward the discharge port by rotating. A first fluid control region includes a first fluid inlet and outlet for allowing a first fluid to pass through the reaction furnace in a predetermined region in the intermediate part. A second fluid control region includes a second fluid inlet and outlet for allowing a second fluid to pass through a region different from the first fluid control region in the intermediate part.

摘要： A recoater supplies a predetermined amount of powder and spreads the supplied powder across a powder bed. The recoater includes a main shaft, a moving mechanism, and a powder guiding part. The main shaft rotates about an axis parallel to a surface of the powder bed. The moving mechanism moves the main shaft in a moving direction perpendicular to the main shaft and parallel to the surface of the powder bed. The powder guiding part is disposed around the main shaft along a predetermined inclination angle relative to the moving direction.

摘要： A performance of a die is improved. An injection hole IH, a nozzle NZa and a nozzle NZb are formed in a center member DIa of a die DI to extend from an extrusion surface ES to an injection surface IS. A heat source HT and a plurality of heat insulating layers HI1 are arranged inside the center member DIa. One of the plurality of heat insulating layers HI1 is adjacent to the nozzle Nzb and is closer to the extrusion surface ES than the heat source HT. The other of the plurality of heat insulating layers HI1 extends in a direction from the extrusion surface ES toward the injection surface IS at a position being farther from the nozzle NZb than the heat source HT.
