WIPO Patent Application WO/2023/211017
Kind Code:
A1
Abstract:
The present invention relates to a method for controlling introduction of different kinds of materials for lamination and, more specifically, to a method for controlling introduction of different kinds of materials for lamination, the method comprising: a tool path generating step of slicing provided three-dimensional image data into multiple slices and determining a nozzle movement path; a sensitivity applying step of deriving the sensitivity of different kinds of materials with regard to an objective function through numerical analysis and applying same to the three-dimensional image data or tool path; and a lamination control step of supplying, mixing, and laminating different kinds of materials. The sensitivity applying step comprises: an objective function designating step of determining an objective function according to the target of optimization of physical characteristics held by the shape of three-dimensional image data; a numerical analysis step of deriving the sensitivity regarding materials by performing numerical analysis according to the objective function; and a mapping step of mapping the sensitivity regarding materials to the three-dimensional image data or tool path. Accordingly, a tool path is generated by mapping the result of numerical analysis, and introduced materials are changed in real time according to the result of numerical analysis through a physical characteristic value database regarding materials used for lamination or the like. Introduced materials, which have conventionally been divided with regard to respective layers, can be changed in real time such that process defects are removed from an object generated through lamination with a 3D printer, and target physical characteristics can be implemented with minimized errors.
