Rapid manufacturing of micro-drilling devices using FFF-type 3D printing technology

Abstract Micro-drilling devices with different blade shapes were fabricated with a rapid and facile manufacturing process using three-dimensional (3D) printing technology. The 3D-printed casting mold was utilized to customize the continuous shape of the blades without the need for expensive manufact...
