3D 3D Forming materials and method for 3D printing based on irregular shape amorphous glass and structure body thereby

摘要

The present invention relates to a molding material for 3D printing which is based on amorphous glass having an irregular shape in powder form, and yet achieves excellent fluidity and sintering properties which enable rapid molding of high-quality products; to a molding method for 3D printing; and to a molded body. The molding material for 3D printing comprises: a glass powder base which is formed by crushing amorphous glass to be an unmelted, irregularly shaped powder; a spherical nanopowder which has an average particle diameter smaller than 1/50 of the average particle diameter of the glass powder base and is mixed with the glass powder base and disposed on the surface of the glass powder base, thereby increasing the fluidity of the irregularly shaped glass powder base when molding through 3D printing.
