Custom-designed biomedical polymer materials can be fabricated rapidly and precisely by 3-dimensional (3D) printing technology according to the requirements of patients with various diseases.In addition

the microscopic structure of the materials can be controlled during the printing process.Therefore

this novel type of technology has unique advantages in the preparation of next generation of biomedical polymer scaffolds.In recent years

the development of biomedical polymer materials by using 3D printing technology has received increasing attention.Various biocompatible polymers have been used to construct 3D scaffolds via 3D printing

and the printed polymeric scaffolds have been tested for in vitro cell culture

soft tissues repair or hard tissue repair in animal models.This review emphasizes recent advances in the development of biomedical polymer materials made by 3D printing technology

and some future applications and challenges of the technology are discussed.
