Eliminating Manual Surface Finishing For
Multi Jet Fusion (MJF) 3D Printed Parts

Eliminate costly manual labor from your additive workflow process with automated, software-driven surface finishing technology.

As more manufacturers are turning to MJF printing, manual or vibratory surface finishing techniques continue to pose limitations and create bottlenecks in the manufacturing process. Current MJF surface finishing methods often require a significant amount of manual labor, the availability and cost of which may cause issues for manufacturers. Alternatively, traditional vibratory post-processing systems can be hazardous to complex and fragile part geometries, leading to frequent inconsistencies and breaks.

This paper covers:

  • The benefits of a novel automated post-printing method for surface finishing.
  • Opportunities to achieve surface finish values of less than 2-microns across a variety of MJF printer platforms.
  • Key considerations like part density and hardness.
  • Manufacturing factors including the impact of print technology and print orientation on the surface profile.

With this alternative approach combining software-driven automation, suspended rotational force, and a patent-pending chemistry solution, surface finishing for MJF parts can be immensely improved with reduced manual labor time, increased consistency, and reduced part breakage.
