Exploring Finishing Methods for Metal 3D Printed Parts

Getting Metal 3D Printed Parts to their Final State

This guide was developed by Desktop Metal, in partnership with Fortune Metal Finishing, to explore different finishing methods for metal 3D printed parts. Almost all metal parts, regardless of manufacturing method, often require some degree of secondary finishing or post processing before they are in their final state. This study focuses on three finishing technologies; centrifugal disc, centrifugal barrel, and media blasting.

In this guide we will explore:

• Fundamental rules of mass finishing
• Challenges of finishing parts produced with metal 3D printing
• Centrifugal disc finishing process and techniques
• Centrifugal barrel finishing process and techniques
• Media blasting finishing processes and techniques
