Abstract
A three-dimensional object production apparatus includes a table, an ink-jet head, a flattening roller, a carriage, and a roller lifting-lowering mechanism. The ink-jet head is configured to eject ink droplets toward the table. The flattening roller is configured to flatten a surface of a layer of the ink. The carriage is configured to carry the ink-jet head and the flattening roller. The roller lifting-lowering mechanism is configured to lift and lower the flattening roller, and includes a roller holding member configured to rotatable hold the flattening roller, and a swing mechanism configured to cause the roller holding member to swing between a contact position and a retracted position. The flattening roller is able to contact the surface of the layer of the ink when the contact position is reached, and is retracted to be more on an upward side than the surface of the layer of the ink when the retracted position is reached.
