3D‐Printed Micromotors for Biomedical Applications. Issue 11 (18th August 2020) - Ye, Junhong
Abstract: Additive manufacturing, known as 3D printing, has been widely applied in various fields owing to the development of 3D printing materials and 3D printing techniques. Compared with other fabrication approaches, 3D printing possesses the advantages of high resolution, high accuracy, unique customizability, and repeatability. Therefore, 3D printing can be widely used to fabricate various microstructures, including micromotors, which are capable of converting external energies into motion and subsequently accomplishing various functions. To date, five types of 3D printing techniques have been used to fabricate self‐propelled micromotors with different structures, ingredients, and functions. This progress report summarizes 3D printing techniques for the fabrication of micromotors and introduces the potential biomedical applications of 3D printed micromotors. The advantages and disadvantages of each typical 3D printing method are discussed as well. Abstract : As a new type of fabrication method, 3D printing is widely applied to fabricate microstructures including micromotors with different shapes, components, and scales. Micromotors are microscale structures that can move in a pre‐arranged track and accomplish various functions. Here, the 3D printing techniques for the fabrication of micromotors are summarized and potential biomedical applications of 3D‐printed micromotors are introduced.
