Claim 0:
1. An additive manufacturing apparatus comprising:
a first portion comprising an elevator stand and configured to support a shaping stage in a first direction;
a member configured to flatten a powder layer laid on the shaping stage by moving in a scanning manner above the shaping stage in a second direction, the member configured to flatten being a flattener, the member having a bottom end extending in a third direction intersecting the second direction;
a second portion configured to selectively heat and/or cure the powder layer laid on the shaping stage; and
a controller,
wherein the controller is configured to execute:
a measuring process of detecting an inclination between the shaping stage and the bottom end of the member in the first and third directions;
an adjustment process of adjusting a positional relationship between the shaping stage and the member on a basis of a detection result of the measuring process;
a formation process of causing the member to perform a scanning movement above the shaping stage to flatten the powder layer after the adjustment process; and
a process of causing the second portion to selectively heat and/or cure the powder layer.
