The invention provides a phosphate glass reinforced 3D printing wire. The phosphate glass reinforced 3D printing wire comprises 1-70% of phosphate glass and 30-99% of a polymer matrix. The invention also provides a preparation method of the wire containing different phosphate glass reinforcements. Compared with the prior art, the chemical components of the phosphate glass are defined more clearly;on the basis, the variety range of the phosphate glass suitable for the method is expanded; the content of the phosphate glass reinforcements is increased; furthermore, the filler content of the phosphate glass reinforcements can be more accurately controlled and blended with the help of a master batch/premix preparation mode; the prepared wire can be well compatible with a series of fused deposition modelling equipment; and the prepared composite material has good mechanical property and human absorbability, and is beneficial to realizing individualized accurate treatment of orthopedic diseases. 本发明提供了一种磷酸盐玻璃增强的3D打印
