Abstract

3D printing (3DP) is becoming a research and development focus in nanobiomaterials as it can quickly and accurately fabricate any desired 3D tissuemodel only if itssize is appropriate. The different material powders (with different dimensional scales) and the printing strategies are the most direct factors influencing 3DP quality. With the development of nanotechnologies, 3DP is adopted more frequently for its rapidness in fabrication and precision in geometry. The fabrication in micro/nanoscale may change the performance of biomaterials and devices because it can retain more anisotropy of biomaterials compared with the traditionally rapid prototyping techniques. Thus, the biosafety issue is especially concerned by many researchers and is investigated in performance and safety of biomaterials and devices. This paper investigates the performance of 3DP in fabrication of nanobiomaterials and devices so as to partially explain how 3DP influences the performance and safety of nanobiomaterials.
