In recent years, it has been realized that there is another contributor to long term part performance-surface finish. Traditional processes that generate form and control fit do not necessarily dictate how that part or assembly will function over time. The mechanism that allows for improved “functionality” for all surfaces is basic to surface performance -to accept the loads imposed and resist wear.

Total process time Two Hours (Not including loading) SME – Networking for Manufacturing Professionals Step Three: High Polish with dry corn cob polishing media or porcelain for 30 Minutes Step Two: Pre-Polish with lighter plastic for 30 Minutes Step One: Heavy grinding with aggressive plastic or ceramic media for 60 – 90 minutes On relatively clean (no heavy heat scale or atmospheric discoloration) titanium or stainless steel 3D printed parts with an initial surface roughness of 300-400 micro-inch Ra here is a typical example process that is used with Centrifugal Iso-Finishing Machines.: The Process: Achieving a polish on a 3D Printed part depends greatly on the material and the initial roughness and scale left over from the printing process. ![]() “Vibratory finishing, centrifugal barrel finishing and turbo-abrasive machining are the three top techniques for finishing gears, improving performance and extending service life.” For additional information or assistance with arranging free sample part finishing High-Speed and Hands-Free Post-Process Surface Finishing of 3D Printed or Additive Manufactured Parts Ray Chalmers Contributing Editor at Modern Machine Shop magazine interviews Dave Davidson, Deburring/Finishing Technologist about processes for the surface finishing of gears. 3 Next Generation Gear Finishing Processes Other than breaking them off the build platform, and transferring them from one barrel of media to another, there was almost no other handling involved. ![]() The top picture is straight off the machine, and the bottom picture is after centrifugal isotropic finishing.
