Additive Manufacturing

The Additive Manufacturing (AM) Industry  requires improved surface finishes to enhance component performance.   Surface finishing of additively manufactured (AM) parts is a leading challenge as the industry pushes

for broader application. Extreme surface roughness and waviness are fundamental realities of the AM building process that must be mitigated to avoid the myriad of problems that they can create.  As a supplier to the Aerospace, Automotive, and Medical Industries for over a decade, REM Surface Engineering has the knowledge and expertise to overcome these challenges with our surface finishing technology

REM’s Extreme ISF® Process is a subtractive finishing process designed specifically for AM components. capable of reducing the extreme surface roughness associated with powder bed fusion additive manufacturing to traditional machining levels, and even to a full ISF Surface (Superfinish) if required.  The traditional ISF Process has broad applications in the AM industry given its processing flexibility.  REM’s ISF Processes are the perfect addition to Additive Manufactured parts in that it are highly adaptable to lot size, alloy change, part customization and part geometry without excessive changeover time and costs.  ISF Processes for AM typically requires no custom tooling or fixtures, which means faster time from powder to product.  ISF Processes are currently available for alloys such as Ti6-4,lnconel®, Aluminum and Stainless Steel.

REM’s ISF Processes  have been used to enhance the performance of dynamic parts in many industries and applications.  A few of the many benefits imparted are reduced friction and wear, improved bending fatigue and improved corrosion  resistance.  The ISF Process is the world’s leading precision isotropic superfinishing process. The ISF Process has broad applications in the AM industry given its processing flexibility.

As Built Additive Surface

 As-Built Surface

  • Increased resistance to bending fatigue
  • Increased tensile strength
  • Increased part cleanliness
  • Reduced turbulence
  • Eliminated FOD risk

Process Results:

  • Complete removal of all surface and near surface defects such as:
    • Loose, partially sintered, and partially melted particles
    •  V-notch failure point
  • Significant reduction in roughness and waviness
  • Removal of all supports (internal and external)
