PURPOSE: To prevent a liquid crystal panel from becoming deteriorated qualitatively due to ultraviolet ray and thereby enhance a value of practical use by forming a first layer plane cured product by projecting a desired plane photoimage to the interface of a resin through a mask and repeating this step to laminate the cured product for the final formation of a three-dimensional form.
CONSTITUTION: A light emitted from a visible light source with a wavelength of 400 to 1500nm as an output wavelength free from an ultraviolet wavelength is emitted to a photocurable resin containing a chemical compound with at least, one unsaturated double bond in a single molecule or/and an epoxy compound and a metallocene compound under focus adjustment and convergent degree adjustment. Further, thus the light permeates a liquid crystal panel 5 controlled by a control device 8 under a pattern control. Consequently, a first layer plane cured product is obtained by projecting a desired plane light image to the interface of the resin through a mask. For the second and following layers, a thin layer of resin is applied to the layer formed after the sequential formation of the cured products, and a three-dimensional form is obtained by repeating the above laminating procedures.
