Abstract

A three-dimensional modeling apparatus includes an ejection portion capable of ejecting a fluid material, which is a material of an object, and a control portion that forms a laminated body in which one layer or more of cross-section bodies are laminated by executing one or more repetitions of a cross-section body formation process, which forms a cross-section body equivalent to one layer of the object by controlling the ejection portion and ejecting the fluid material. The control portion executes a correction process that ejects the fluid material onto a target correction location, which is at least a portion of an outline section of an upper surface of the laminated body.

First claim

What is claimed is:

1. A three-dimensional modeling apparatus that models a three-dimensional object, the apparatus comprising:
an ejection member configured to eject a fluid material in a dot shape so as to model the object; and
a controller configured to execute a program so as to:
read model data from an external computer or a recording medium, the model data including cross-section body data and correction data, the cross-section body data corresponding to information of a cross-section body, the correction data corresponding to information of a target correction area in which a number of adjacent dots is smaller than other areas;
form a laminated body in which one layer or more of the cross-section bodies are laminated by executing one or more repetitions of a cross-section body formation process, which forms the cross-section body equivalent to one layer of the object by controlling the ejection member and ejecting the fluid material; and
execute a correction process that ejects the fluid material onto the target correction area, which is at least a portion of an outline section on an upper surface of the laminated body.

2. The three-dimensional modeling apparatus according to claim 1 ,
wherein the controller is configured to continuously eject the fluid material along a shape of the target correction area in the correction process.

3. The three-dimensional modeling apparatus according to claim 1 ,
wherein, when a portion, in which a shape of the cross-section body to be formed on the laminated body and a shape of the target correction area coincide with each other, is not present, the controller is configured to perform the correction process simultaneously with the cross-section body formation process.
