Surface Finishing of 3D Metal Printed Parts

The following are examples of the various surface finishing recipes that we have developed. These can be used for all types of Additive Manufactured materials and technology types, including but not limited to the list below.  Each picture indicates a different finishing process that used our equipment and abrasive/polishing media. The roughness average (Ra) is measured in micro-inches. These finishes are industry standard for each material, but we also develop custom finishing recipes to meet your specifications. Let us process your samples and find a result that is right for you.
