Abstract

A method of manufacturing a three-dimensionally formed object includes: forming a layer using a flowable composition including constituent material particles of a three-dimensionally formed object and a flowable composition including support portion-forming particles for forming a support portion which supports the three-dimensionally formed object during the formation of the three-dimensionally formed object; and imparting energy to the constituent material particles and the support portion-forming particles, in which in the imparting of the energy, the energy is imparted such that a temperature of the constituent material particles and a temperature of the support portion-forming particles are equal to or higher than a sintering temperature of the constituent material particles and are lower than a sintering temperature of the support portion-forming particles.
