Abstract: An additive manufacturing apparatus includes a chamber, a material layer former, an inert gas supplier, and a material supply unit. The material supply unit includes a material tank, a transporter, and a sieve. The material tank stores material. The transporter transports the material discharged from the chamber and the material tank to the highest level of a conveyance route of the material. The sieve is provided below the transporter and above the chamber, removes impurities from the material sent from the transporter and then discharge the material downward to replenish the material layer former with the material.

Abstract: An additive manufacturing apparatus includes a chamber, a material layer former, and a guide member. The material layer former includes a base on which a molding region is present, a recoater head that moves on the base in a horizontal direction while discharging material, and a blade that levels the material to form a material layer. The guide member includes a feed chute that is configured to enable the material to be flowed, a shaft that is provided to shut a lower end portion of the feed chute and has a through hole, and a rotary actuator that rotates the shaft. The discharge of the material is switched to an on- or off-state by rotating the shaft.

Abstract: A lamination molding apparatus capable of stably supplying material powder on a molding table. Provided is a lamination molding apparatus including a chamber, a recoater head, and a recoater head driving mechanism. The chamber covers a molding region. The recoater head comprises a material case and is configured to be moved so as to form a material powder layer. The material case includes a case outlet for discharging the material powder and a pair of inclined side surfaces arranged with the case outlet interposed therebetween. The inclined side surfaces are inclined toward the case outlet so that inclination angles between a horizontal plane and the inclined side surfaces are different from each other. The recoater head driving mechanism includes a motor and a control unit, and the control unit is configured to vibrate the recoater head to facilitate discharge of the material powder.

Abstract: A lamination molding apparatus includes a table, powder holding walls, a table driving device, a bucket, and a cover. The powder holding walls surround the table and hold material powder together with the table. The table driving device includes a linear actuator for outputting linear motion and a guide for transmitting the linear motion to the table and moving the table in a vertical direction. The bucket is disposed under the table and stores the material powder falling from between the table and the powder holding walls. The cover surrounds the table driving device between the table and the bucket. At least one portion of the linear actuator and the guide surrounded by the cover or the bucket is arranged along the vertical direction.
