Title:
METHOD AND APPARATUS FOR MANUFACTURING THREE-DIMENSIONAL MODELED OBJECT, AND METHOD FOR MANUFACTURING ARTIFICIAL TOOTH MODELED OBJECT
Document Type and Number:
Japanese Patent JP2023140216
Kind Code:
A
Abstract:
To provide a method for manufacturing a three-dimensional modeled object with high-precision colors capable of exhibiting a color gradation characteristic to the three-dimensional modeled object.SOLUTION: A method for manufacturing a three-dimensional modeled object using a base curable composition set comprising a curable composition A and a curable composition B, and a curable composition C includes: a base cured article manufacturing step for discharging and curing the curable composition A and/or the curable composition B using an inkjet system to manufacture a base cured article; and a cured article C manufacturing step for discharging and curing the curable composition C containing a color material using the inkjet system to manufacture a cured article C. A landing area C formed by landing of the discharged curable composition C is smaller than a base landing area formed by landing of the discharged curable composition A and the discharged curable composition B. An absolute value of a difference of total light transmittance between the cured article A of the curable composition A and the cured article B of the curable composition B is 10% or more.SELECTED DRAWING: None
