Abstract

Provided is a stack forming apparatus including a molded article forming agent ejecting unit, that ejects a molded article forming agent for forming a three dimensional shaped product, onto a shaping stand, a surface modification unit that modifies wettability of surfaces of the molded article forming agent, and a control unit that controls the molded article forming agent ejecting section and the surface modification unit so that the three dimensional shaped product is formed by stacking the molded article forming agent through the repetition of ejection of the molded article forming agent and modification of the surface of the molded article forming agent.

Claims

1. A stack forming apparatus comprising:

a molded article forming agent ejecting unit, that ejects a molded article forming agent for forming a three dimensional shaped product, onto a shaping stand;

a surface modification unit that modifies wettability of surfaces of the molded article forming agent; and

a control unit that controls the molded article forming agent ejecting section and the surface modification unit so that the three dimensional shaped product is formed by stacking the molded article forming agent through the repetition of ejection of the molded article forming agent and modification of the surface of the molded article forming agent.

2. The stack forming apparatus according to claim 1, further comprising:

a water repellent material ejecting unit that ejects a water repellent material,

wherein the control unit controls the water repellent material ejecting unit so that the water repellent material is ejected in a region that is adjacent to a region in which at least the molded article forming agent is ejected before the molded article forming agent is ejected.

3. The stack forming apparatus according to claim 2,

wherein the water repellent material is concurrently used as a support material for assisting in the forming of the three dimensional shaped product.

4. The stack forming apparatus according to claim 2,

wherein an amount of drops of the water repellent material, that is ejected from the water repellent material ejecting unit, is less than an amount of drops of the molded article forming agent that is ejected from the molded article forming agent ejecting section.

5. The stack forming apparatus according to claim 3,

wherein an amount of drops of the water repellent material, which is ejected from the water repellent material ejecting unit, is less than an amount of drops of the molded article forming agent that is ejected from the molded article forming agent ejecting section.

6. A non-transitory computer readable medium storing a stack forming program that causes a computer to function as a control unit of the stack forming apparatus according to claim 1.

7. A non-transitory computer readable medium storing a stack forming program that causes a computer to function as a control unit of the stack forming apparatus according to claim 2.
