Title:
METHOD OF PHOTOFABRICATION
Document Type and Number:
WIPO Patent Application WO/2008/038541
Kind Code:
A1
Abstract:
A method of photofabrication in which a model pattern of photofabrication product can
be taken out with high precision, and in which even in the fabrication of a pattern of
minute structure or microstructure, fabrication with high precision can be
performed.There is provided a method of photofabrication comprising irradiating a
photohardening composition layer with light to thereby convert the photohardening composition
to a hardened resin layer, forming once more a photohardening composition layer
on the hardened resin layer, irradiating the same with light to thereby convert
the photohardening composition to a further hardened resin layer and repeating
these operations to thereby obtain a matter of three-dimensional configuration
composed of an integrated laminate of hardened resin layers, wherein the photohardening
composition layer is produced by coating a base material, or hardened resin layer
formed on the base material, with a photohardening resin composition containing
a resin, an ethylenically unsaturated compound and an organic solvent and removing
the organic solvent contained in the photohardening resin composition, and
wherein after completion of the formation of all the hardened resin layers, any
unhardened photohardening composition within the hardened resin layers is
removed to thereby accomplish formation of a matter of three-dimensional configuration.
