Abstract

Abstract A method of and apparatus (1) for producing a three-­dimensional object are provided, in which a beam (18) from beam oscillating means (11) is irradiated on a liquid surface of a liquid photo-curable resin (4) to form a cured resin layer having a pattern corresponding to a shape of an exploded plane which results from exploding a desired three-­dimensional object image by a certain direction, a liquid photo-curable resin is placed on the cured resin layer and a beam is again irradiated on a liquid surface of the liquid photo-curable resin layer thereby to sequentially laminated a cured resin layer onto the already-cured resin layer, so as to form a desired three-dimensional object (47). The method and apparatus are characterised by the use of configuration scanning in which a configuration line of the exploded plane is scanned by the beam irradiation based on a vector-­scanning system and field scanning in which a whole surface of the exploded plane is scanned according to a raster-­scanning system.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 152 words
A method of producing a three-dimensional object in which a beam is irradiated on a liquid surface of a liquid photo-curable resin to form a cured resin layer having a pattern corresponding to a shape of an exploded plane which results from exploding a three-dimensional object image in one direction, a liquid photo-curable resin is placed on said cured resin layer and a beam is again irradiated on a liquid surface of the liquid photo-curable resin layer to thereby to sequentially laminate a cured resin layer onto the already-cured resin layer, so as to form a desired three-dimensional object, said method comprising the steps of: (a) carrying out configuration scanning in which a configuration line of said exploded plane is scanned by said beam irradiation based on a vector-scanning system; and (b) carrying out field scanning in which a whole surface of said exploded plane is scanned according to a raster-scanning system.
Claim 2
Independent Claim 152 words
A method of producing a three-dimensional object in which a beam is irradiated on a liquid surface of a liquid photo-curable resin to form a cured resin layer having a pattern corresponding to a shape of an exploded plane which results from exploding a three-dimensional object image in one direction, a liquid photo-curable resin is placed on said cured resin layer and a beam is again irradiated on a liquid surface of the liquid photo-curable resin layer to thereby to sequentially laminate a cured resin layer onto the already-cured resin layer, so as to form a desired three-dimensional object, said method comprising the steps of: (a) carrying out configuration scanning in which a configuration line of said exploded plane is scanned by said beam irradiation based on a vector-scanning system; and (b) carrying out field scanning in which a whole surface of said exploded plane is scanned according to a raster-scanning system.
Claim 3
Dependent Claim 28 words
The method according to claim 1, wherein said configuration scanning is performed each time a cured resin layer is formed by one or a plurality of field scannings.
Claim 4
Dependent Claim 29 words
The method according to claim 1 or 2, wherein said raster-scanning is performed such that the scanning direction thereof is changed on each of a number of exploded planes.
Claim 5
Dependent Claim 41 words
The method according to claim 1, 2 or 3, wherein said raster-scanning is performed such that the raster-­scanning direction of a preceding field scanning and a raster-scanning direction of the next field scanning are different from each other in scanning direction.
Claim 6
Dependent Claim 31 words
The method according to claim 3 or 4, wherein said raster-scanning is performed such that scanning directions thereof on said exploded planes are different from each other by substantially 90 degrees.
Claim 7
Independent Claim 152 words
An apparatus for producing a three-dimensional object in which a beam is irradiated on a liquid surface of a liquid photo-curable resin to form a cured resin layer having a pattern corresponding to a shape of an exploded plane which results from exploding a three-dimensional object image in one direction, a liquid photo-curable resin is placed on said cured resin layer and a beam is again irradiated on a liquid surface of the liquid photo-curable resin layer thereby to sequentially laminate a cured resin layer onto the already-cured resin layer, so as to form a desired three-dimensional object, said apparatus comprising: (1) means for performing configuration scanning in which a configuration line of said exploded plane is scanned by said beam irradiation based on a vector-scanning system; and (2) beam scanning means for performing field scanning in which a whole surface of said exploded plane is scanned according to a raster-scanning system.
Claim 8
Independent Claim 152 words
An apparatus for producing a three-dimensional object in which a beam is irradiated on a liquid surface of a liquid photo-curable resin to form a cured resin layer having a pattern corresponding to a shape of an exploded plane which results from exploding a three-dimensional object image in one direction, a liquid photo-curable resin is placed on said cured resin layer and a beam is again irradiated on a liquid surface of the liquid photo-curable resin layer thereby to sequentially laminate a cured resin layer onto the already-cured resin layer, so as to form a desired three-dimensional object, said apparatus comprising: (1) means for performing configuration scanning in which a configuration line of said exploded plane is scanned by said beam irradiation based on a vector-scanning system; and (2) beam scanning means for performing field scanning in which a whole surface of said exploded plane is scanned according to a raster-scanning system.
Claim 9
Dependent Claim 46 words
The apparatus according to claim 6, wherein said scanning means is composed of first deflecting means for deflecting the beam in one straight line direction on said exploded plane and second deflecting means for deflecting the beam in the direction perpendicular to said straight line direction.
