THREE-DIMENSIONAL MOLDING APPARATUS, PRODUCTION METHOD OF THREE-DIMENSIONAL MOLDED OBJECT, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To solve such a problem that qualities of a molded object degrade by irregular generation of a portion having a high density and a portion having a low density due to migration of a powder by liquid bridging force.SOLUTION: When droplets 100A, 100B of a molding liquid 10 are discharged and deposited on positions adjoining to each other of a powder layer 31, a preceding droplet 100A is first discharged and then a succeeding droplet 100B is discharged within a time period in which a contact angle between the preceding droplet 100A and a powder 20 remains larger than 90 degrees. Thus, the preceding droplet 100A first deposited and the succeeding droplet 100B deposited later are unified to decrease density reduction.SELECTED DRAWING: Figure 10
