Method for preparing porous tantalum medical implant material through three-dimensional printing forming |
| abstract |
A method for preparing a porous tantalum medical implant material comprises: feeding mixed tantalum power formed by mixing pure tantalum powder and a forming agent into a printing platform of a three-dimensional printer, and rolling and paving; a printing head of the three-dimensional printer spraying an adhesion agent to adhere the mixed tantalum powder so as to form a two-dimensional plane; descending a working table by 80 to 100 μm, and processing the next layer; accumulating and forming layer by layer; removing the tantalum powder particles which are not adhered to obtain an initially formed sample; and performing posttreatment such as degreasing, vacuum sintering, and cooling to obtain the porous tantalum medical implant material. The volume ratio of the pure tantalum powder to the forming agent is (60-80):(20-40), and the adhesion agent is alpha-cyanoacrylate adhesive in the mass percent of 1. The pores of the porous tantalum medical implant material prepared by the method are completely connected in a three-dimensional way; the porous tantalum medical implant material prepared by the method is high in biocompatibility, and meanwhile, has the mechanical property being consistent with that of weight-bearing bone tissues of a human body. |
