1. A sculpted object formed from a cured product of a photocurable resin composition, the sculpted object comprising:
a sculpted surface; and
a support removal trace recessed with respect to the sculpted surface,
wherein the support removal trace has a higher surface roughness than a surface roughness of the sculpted surface, and
wherein the support removal trace has an arithmetic mean roughness Ra of 10 μm to 15 μm.
 
10. A sculpted object formed from a cured product of a photocurable resin composition, the sculpted object comprising:
a sculpted surface; and
a support removal trace recessed with respect to the sculpted surface,
wherein the support removal trace has a higher surface roughness than a surface roughness of the sculpted surface, and
wherein a ratio of a curing degree of part of the sculpted object where the support removal trace is formed to a curing degree of part of the sculpted object where the sculpted surface is formed is 0.4 to 0.8.
