1. A method of making a molded product, comprising:
pouring a light curing resin material into a mold;
emitting light to the light curing resin material, the light being partly blocked with a mask; and
removing an uncured portion of the light curing resin material, the uncured portion remaining uncured based on blockage of the light.
2. The method according to claim 1, further comprising absorbing the light that penetrates through the mold.
3. The method according to claim 1, wherein the mask is fixed to the mold for the blockage of the light.
4. The method according to claim 1, further comprising emitting light to the light curing resin material behind the mask.
5. A method of making a molded product, comprising:
pouring a light curing resin material into a mold;
emitting light to the light curing resin material in a first direction, the light being partly blocked with a mask;
emitting light to the mask in a second direction opposite to the first direction; and
removing an uncured portion of the light curing resin material, the uncured portion remaining uncured based on blockage of the light.
6. The method according to claim 5, wherein the mask is fixed to the mold for blockage of the light.
7. A molding apparatus comprising:
a mold defining a cavity, the mold at least partly having optical permeability;
a light emission unit designed to emit a parallel beam to the mold; and
a mask fixed to the mold at a position between the cavity and the light emission unit, the mask having optical impermeability.
