Research Progress of Robot Technology in In situ 3D Bioprinting.

Three-dimensional (3D) bioprinting is an emerging research direction in bio-manufacturing, a landmark in the shift from traditional manufacturing to high-end manufacturing. It integrates manufacturing science, biomedicine, information technology, and material science. In situ bioprinting is a type of 3D bioprinting which aims to print tissues or organs directly on defective sites in the human body. Printed materials can grow and proliferate in the human body; therefore, the graft is similar to the target tissues or organs and could accurately match the defective site. This article mainly summarizes the current status of robotic applications in the medical field and reviews its research progress in in situ 3D bioprinting.
