Title:
METHOD FOR FORMING THREE-DIMENSIONAL OBJECT AND DEVICE THEREFOR
Document Type and Number:
Japanese Patent JP3443365
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To perform the automatic designing economically with rapidity and high reliability by providing a step to partially change stored sets of data for defining the solid part of the shape of an object and coverting the solid part into a part consisting of a region where it is cured or a region where it is maintained in an uncured state according to each of exposure levels.
SOLUTION: When a design displayed on the output image screen of a computer is satisfactory, parts are manufactured and when the design needs to be corrected, a change is repeatedly made through the computer. In this case, a pattern for stimulating each of many superposed thin layers 30a, 30b, 30c of a transferable fluid medium 22 is changed partially in a data processing step 25. Further, alteration data for converting the solid part to the part comprising a region where it is cured according to a first exposure level and a region where it is cured according to a second lower exposure level or a region where it is maintained in an uncured state while each of the thin layers 30a, 30b, 30c is initially formed, is created.
