ADDITIVE MANUFACTURING APPARATUS

原文（中文）

[Object] To achieve highly accurate position control of a table and improve the accuracy of additive manufacturing in powder-bed additive manufacturing. [Solution] [SOLUTION TO PROBLEM] An additive manufacturing apparatusincludes: a tableon which a powder material M is to be spread over; a material supply mechanismconfigured to supply a preset weight of the powder material to the table; a drive mechanismconfigured to support the table and move the table in an up-down direction; a support structureconfigured to support the drive mechanism and support the table via the drive mechanism; a control unitconfigured to control the position of the table in the up-down direction at the time of supply of the powder material to the table. The control unitis configured to correct the position of the table in the up-down direction at the time of supply of the powder material to the table based on a posture change of at least one of the drive mechanismand the support structuredue to the weight of the powder material M spread on the table
