Optical molding method
First Claim
1. An optical molding method for making a target object comprising the steps of:
- (a) radiating a light flux onto a photocurable fluid substance while moving said light flux to form and cure a layer of a target object;
(b) then supplying a photocurable fluid substance on a side of the cured portion;
(c) then radiating a light flux onto said supplied photocurable fluid substance while moving said light flux to form and cure another layer of said target object;
(d) repeating steps (a)-(c) to successively laminate said layers and form said target object;
the improvement comprising;
providing at least one light flux having a large diameter light and at least one light flux having a small diameter; and
radiating the large diameter light flux and the small diameter light flux onto the photocurable fluid substance to form and cure a target object, said target object having a main part, detailed portions and surface portions, wherein said large diameter light flux is radiated onto the photocurable substance to form and cure the main part and said small diameter light flux is radiated onto the photocurable substance to form and cure the detailed and surface portions so that said target object is formed and cured by combinations of the large diameter light flux and the small diameter light flux.

Abstract
An optical molding method includes the step of radiating a light flux onto a photocurable fluid substance while moving the light flux in such a manner as to draw a section of a target object so as to cure the irradiated portion. A plurality of light fluxes having different diameters is used in such a manner that only a light flux having a large diameter, or both a light flux having a large diameter and a light flux having a small diameter are used for a section having a thickness larger than the diameter of the light flux having a large diameter, while only a light flux having a small diameter is used for a section having a thickness smaller than the diameter of the light flux having a large diameter.
