Original Abstract Submitted
To form a cured portion quickly. A stereolithography apparatus includes a splitting/coupling unit, a first spatial light modulation unit, and a second spatial light modulation unit. The splitting/coupling unit splits incident light applied to a photocurable resin to form a cured portion, in a first direction and a second direction, couples light incident from the first direction and light incident from the second direction, and emits the coupled light in a third direction. The first spatial light modulation unit is arranged in the first direction to modulate a light beam from the splitting/coupling unit into a light beam having a first pattern that is a pattern of the cured portion and emits the light beam having the first pattern to the splitting/coupling unit, for coupling. The second spatial light modulation unit is arranged in the second direction to modulate a light beam from the splitting/coupling unit to a light beam having a second pattern in the vicinity of the first pattern and emits the light beam having the second pattern to the splitting/coupling unit, for coupling.
