Centrifugal Isotropic Finishing has been shown to be useful in reducing the rough surfaces common to 3D printed parts. Below is an example of surface finishes that can be achieved with the method. The slides provide profilomic and areal data tabulated by Jack Clark, President of Surface Analytics. This work was performed by Jack for a study being made by SME’s Machining/Material Removal Technical Community. The slides show surface readings from a part pictured above as printed, and then following centrifugal isotropic finishing. The measurements were made in both 2D and 3D. To summarize, in this test, surface roughness was reduced from 356.24µin Ra. to 12.06µin Ra.
