Abstract
The present invention relates to a forming material for three-dimensional (3D) printing, a forming method for 3D printing, and a formed object, wherein, while being based on an amorphous glass powder shaped irregularly, the forming material for 3D printing ensures excellent flowability and sinterability such that it enables the formation of high-quality products at high speed. The forming material for 3D printing consists of a parent glass powder in the form of an unmelted powder irregularly shaped by crushing amorphous glass; and a spherical nanopowder that has an average particle diameter equal to or less than 1/50th of the average particle diameter of the parent glass powder and is mixed in such a way that it can be disposed on a surface of the parent glass powder to enhance the flowability of the irregularly shaped parent glass powder during the formation of an object by 3D printing.
