Title:
THREE-DIMENSIONAL MOLDING APPARATUS AND THREE-DIMENSIONAL MOLDING METHOD
Document Type and Number:
Japanese Patent JP2016101731
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a three-dimensional molding apparatus and a three-dimensional molding method, by which a bridge structure can be formed without a support material.SOLUTION: The three-dimensional molding apparatus is configured to discharge a fused resin from a head unit to form a resin layer and to stack the resin layers to produce a three-dimensional molded object as well as to form such a bridge structure that a flat plane is mounted on two molded objects having substantially the same height without using a support material. The three-dimensional molding apparatus includes control means for controlling in such a manner that: in the first layer of the flat plane in the bridge structure, a plurality of lines of linear molded objects extending in a predetermined direction is formed while a resin discharge speed, which is a speed for discharging the resin from the head unit, is lower than a head moving speed, which is a moving speed of the head unit; in the second layer of the flat plane, a plurality of lines extending in a direction intersecting the predetermined direction is formed; and in the third layer of the flat plane, a plurality of lines extending in the predetermined direction is formed.SELECTED DRAWING: Figure 3
