Emerging 4D printing technologies for biomedical applications

Although 4D printing is considered very promising for various biomedical applications - such as tissue scaffolds, neural scaffolds, grafts and stents, cardiac patches and valves, even bionic constructs - its broad-scale adoption for clinical use and tissue engineering purposes is complicated by a notable limitation of printable smart materials and the simplistic nature of achievable responses possible with current sources of stimulation. Nevertheless, 4D printing may offer a more favorable fabrication approach over 3D printing, as 4D constructs can respond to internal and/or external stimuli.
