Abstract
A shaping apparatus includes a storage section that stores in advance a first relationship between a temperature of a shaping material and a heating time at a time at which oxidation of the shaping material starts as the shaping material is heated; and a control section that estimates a timing at which the oxidation of a material layer starts, based on an acquisition result from a temperature acquisition section, a measurement result from a time measurement section, and the first relationship stored in the storage section when the material layer on a conveyance body is preheated by a preheating section, and reduces a front surface temperature of the material layer on the conveyance body before the oxidation of the material layer starts.
