The application and significance of 3D printing technology in biomedicine

Abstract

3D printing technology, also known as rapid prototyping technology, is an emerging production and manufacturing method. Medical researchers can create various medical devices for patients' bodies with greater accuracy by converting 3D digital graphics from computer-aided design into physical entities and printing 3D objects layer by layer. Thriving as medicine is, 3D printing, being a widely used and promising technology, will make significant contributions to the progress of biomedical science in multiple directions. The fundamental principle of this technology is akin to building blocks, where small parts are assembled into a comprehensive structure, utilizing materials such as plastic, metal, ceramics, etc. In the production of medical equipment under traditional manufacturing methods, a significant amount of manual debugging is sometimes necessary, which often results in the waste of considerable time and resources. Nonetheless, the manufacturing technique of 3D printing can rapidly and precisely create intricate instruments, as well as produce implants or tissue models. The main focus of this article is to analyze recent progress, applications and restriction prospects of 3D printing in medical applications. The advancement that 3D technology gains across different domains and levels is poised to significantly influence future medical treatment. The significance is to clarify the application and significance of 3D printing technology in the biomedical field. Through the review and analysis of relevant literature, a comprehensive understanding of the research progress and existing problems on 3D printing in the biomedical domain be gained, providing references and inspiration for future research.
