Applications of 3D printing in tumor treatment

As an emerging technology relevant to materials science, 3D printing technology simplifies material production process, shortens the preparation cycle, and provides a broader space for disease treatment. This review introduces the latest development in 3D printing, the goal is showing summary of the preparation and the utilization of this technology. We first describe the familiar biological ink for 3d printing. Then, we focus on different applications, including drug delivery, tumor modeling, and organ printing. Later, we described the application of this technology in some disciplines, including neurosurgery, gastrointestinal surgery, and orthopedics. Finally, the recent challenges and prospects of 3D printing are presented.
