COMPOSITE BIOMEDICAL IMPLANT MATERIAL AND PREPARATION METHOD THEREFOR

WIPO Patent Application WO/2017/152541

A1

A composite material, a preparation method therefor, and application thereof as a composite biomedical implant material. The composite material comprises, in percentage by volume: stainless steel powder 85-95%; and calcium silicate powder 5-15%. A preparation method for the composite biomedical implant material comprises: mixing components, and then preparing composite powder by means of a stirring ball milling process; constructing a three-dimensional human body implant model followed by calculating a two-dimensional cross section by means of a sectioning process; then laying the powder, and scanning and melting the composite powder by using a laser beam to form a two-dimensional cross section of the implant; repeating the above steps to form the three-dimensional implant model; and obtaining the composite biomedical implant material by means of post-processing. The mechanical properties and biocompatibility of the said composite biomedical implant material can be effectively controlled, and requirements for an implant material used in the human body are met.
