Abstract
A shaping apparatus includes: a movement processing unit that heats a droplet such that a temperature of the droplet on a peripheral side in a horizontal direction becomes higher than that on a center side in the horizontal direction and move the droplet by moving a heating area; and a shaping unit that performs shaping by partially changing the droplet into a solid in a predetermined shaping area.
