3D printing system and method for controlling the size of molten pool formed during 3D printing process

摘要

Disclosed is a method and apparatus for estimating the depth of a molten pool formed during a 3D printing process. A method of estimating a depth of a molten pool formed during a 3D printing process, comprising: measuring a surface temperature of a molten pool formed during fixing of 3D printing; Extracting the length and width of the molten pool; Deriving a temperature distribution equation of the molten pool; Setting a melting point boundary of the molten pool; And estimating the depth of the molten pool in which the boundary is set using the temperature distribution equation of the molten pool.
