3D printing composite material evaluation method and system

The invention discloses a 3D printing composite material evaluation method and system, and belongs to the technical field of material design. Comprising the steps of obtaining performance data of each to-be-evaluated composite material; determining an evaluation index according to the performance data; constructing an index system according to the evaluation indexes; based on the index system, processing the evaluation indexes through a triangular fuzzy theory, obtaining a standardized decision matrix, performing weighting processing, and generating a boundary approximate region matrix; respectively calculating the distance between each to-be-evaluated composite material and the boundary approximate region matrix, sorting each to-be-evaluated composite material according to the distance, and obtaining the evaluation result of the to-be-evaluated composite material. Accurate evaluation of the 3D printing composite material can be realized, and the problems that an existing evaluation method is too strong in su
