Abstract

Abstract A photo-solidification modeling device for forming a solidified image having a desired model shape by exposing to light a liquid capable of being solidified in receipt of the light in a region corresponding to the desired model shape. Data indicative of a regularly spaced region is provided in addition to data indicative of the region corresponding to the desired model shape, and an exposure region is set according to the additional data. Accordingly, the generation of distortion of the model during the modeling process can be well suppressed without considering and inputting a position or the like of the supporting rib.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 108 words
A photo-solidification modeling device for forming a solidified model having a desired model shape by exposing to a light a liquid capable of being solidified on receipt of the light, the photo-solidification modeling device comprising: means for generating data indicative of said desired model shape; means for generating data indicative of regularly spaced regions independent of the generation of said data indicative of said desired model shape; means for combining said data indicative of said desired model shape and said data indicative of said regularly spaced regions to provide exposure region data; and means for exposing the light to the liquid in accordance with said exposure region data.
Claim 2
Dependent Claim 108 words
A photo-solidification modeling device for forming a solidified model having a desired model shape by exposing to a light a liquid capable of being solidified on receipt of the light, the photo-solidification modeling device comprising: means for generating data indicative of said desired model shape; means for generating data indicative of regularly spaced regions independent of the generation of said data indicative of said desired model shape; means for combining said data indicative of said desired model shape and said data indicative of said regularly spaced regions to provide exposure region data; and means for exposing the light to the liquid in accordance with said exposure region data.
Claim 3
Dependent Claim 38 words
The photo-solidification modeling device of claim 1, wherein said means for generating said data indicative of said regularly spaced regions includes means for selecting a pattern of said regularly spaced regions from a plurality of predetermined regular patterns.
Claim 4
Dependent Claim 32 words
The photo-solidification modeling device of claim 1, wherein said means for generating said data indicative of said regularly spaced regions includes means for selecting a spatial range of said regularly spaced regions.
Claim 5
Dependent Claim 56 words
The photo-solidification modeling device of claim 3, wherein said means for selecting said spatial range of said regularly spaced regions includes means for selecting said spatial range as any one of a region outside said desired model shape, a region below said desired model shape, and a region both inside and outside said desired model shape.
