Polishing of metal 3D printed parts with complex geometry: Visualizing the influence on geometrical features using centrifugal disk finishing

Parts produced with metal additive manufacturing often suffer from a poor surface finish. Surface finishing techniques are effective to improve the quality of 3D printed surfaces, however they have as downsides that they also slightly change the geometry of the part, in an unpredictable way. This effect on the geometrical features of complex...

Designing for Post-Processing: A Case Study of a 3D Printed Surgical Instrument

In this report a design is proposed for a laparoscopic gripper that can be manufactured with metal 3D printing and polished with mass finishing. The design is a continuation of the development of a laparoscopic gripper that can be 3D printed in plastic. Laparoscopic grippers 3D printed solely out of metal have not yet been presented....
