1. An optical molding method comprising the steps of:

  • (a) moving a base away from a horizontally-disposed aperture by a predetermined distance;

    (b) irradiating light through said aperture to cure a photocurable resin and form a first cured layer on said base;

    (c) inclining said aperture relative to said base from a horizontally-disposed position so that said first cured layer is separated from said aperture;

    (d) moving said base away from said aperture by a distance corresponding to a thickness of a second layer;

    (e) returning said aperture to said horizontally-disposed position;

    (f) irradiating light through said aperture to cure a photocurable resin and form a second cured layer on said first cured layer;

    (g) inclining said aperture relative to said base from said horizontally-disposed position so that said second cured layer is separated from said aperture; and

    repeating steps (d)-(g) to form third and later cured layer in series, thereby obtaining a cured object.
