Abstract:

BACKGROUND: With the development of life sciences and manufacturing science, the application of three-dimensional (3D) printing in the medical field has become increasingly widespread.

OBJECTIVE: To analyze the level of application of 3D printing technology in the medical field, and to discuss the trends and constraints of 3D printing.
METHODS: A computer-based retrieval of articles concerning 3D printing in the biomedical field was performed in CNKI, WanFang, Springerlink and PubMed databases. The key words were “3D printing; biomedical; tissue engineering” in Chinese or English and the retrieval time of papers was set as 2005-2017.

RESULTS AND CONCLUSION: At present, the 3D printing technologies applied in the medical field mainly include stereolithography, selective laser sintering, fused deposition manufacturing, and 3D bioprinting. Different printing technologies have different application scopes. According to the biological properties of molding materials, the biological printing technology is divided into four levels of application: medical pre-operation model, in vivo implants, tissue engineering scaffolds, and cell structures. The printing procedures consist of pre-processing, printing processes, and post-processing. Existing biological manufacturing technologies are able to realize the precise positioning of components in the 3D space. Further investigation will focus on the balance of printing characteristics and biological characteristics of the materials and the fusion of multi-materials.
