文题释义:
三维生物打印:指用加压方式将黏性液体材料从针筒或注射器中挤压出来,在打印平台上固定成型的技术。生物细胞打印都是在低温下进行,但挤压打印方式不限于低温条件,高温条件下也可通过加压方式将聚合物等材料挤压成型,通过调节打印平台温度可调整固定成型速度。
细胞结构体:指含有活性细胞的体外构造具有生物活性的三维多细胞体系,细胞结构体包含支架及附着其上生长的活细胞,支架材料为生物材料,可以是水凝胶、明胶与各种黏性剂的混合液。
 
 
背景:随着生命科学与制造科学的发展,三维打印在医学领域的应用范围逐渐广泛。
目的:分析三维打印技术在医疗领域应用的层次,讨论三维打印发展趋势及制约因素。
方法:应用计算机检索中国知网数据库、万方数据库、Springerlink数据库及PubMed数据库中关于三维打印在生物医疗领域的相关文献,以“三维打印、生物医疗、组织工程”与“3D Printing,Biomedical,Tissue Engineering”为检索词,设定论文检索年限为2005至2017年。

结果与结论:目前,在医疗领域应用的三维打印技术主要包括立体光刻技术、选择性激光烧结技术、熔融沉积制造和三维生物打印等,不同打印技术的应用范围不同。根据成型材料的生物学性能不同,将生物打印技术分为4个层次的应用:医学术前模型、体内植入物、组织工程支架、细胞结构体;其流程包括前处理、打印过程与后处理3个阶段。现有生物制造技术已能够实现部件在三维空间的精确定位,下一步的研究重点应在材料打印特性与生物特性的平衡及多材料的融合方面有所突破。

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.
