Automated Surface Finishing

  • Designed for all types of geometries, simple to complex, the NITOR Surface Finishing machine is specifically engineered for 3D printed parts.
  • Works continuously with limited technician involvement required, combined with the ability to finish many parts in the same cycle, speeds overall throughput and ensures that the post-print finishing never hinders the production runs.

Fast Cycle Times

The patent-pending automated surface finish vibratory system is exclusively engineered for additive manufactured parts. Designed to meet the specifications for your desired Roughness Average (Ra) to achieve various types of finishes, the NITOR Surface Finishing is ideal for all 3D printed materials.

PostProcess solution of patent-pending software, user-friendly hardware, and eco-friendly consumables works collectively to deliver exacting surface finishing on all 3D print materials while increasing the throughput of your production.

Advanced Surface Finishing Technology

The unique Suspended Rotational Force (SRF) technology utilizes a circulating motion with immersion in a mixture of composite abrasive and fluid for applying even mechanical force at the surface level. Driven by AUTOMAT3D™ platform, which controls proprietary Agitation Algorithms.

The NITOR’s advanced software provides real-time decision making for your desired surface finish while preserving the fine-feature detail of unique geometries. Precisely controlling all variables, including heat, frequency, amplitude, and lubricity, our solution ensures less breakage. In addition, you have the capability to “set it and forget it” with recipe programming that no other system can offer.


All of the patent-pending engineered solutions have been developed for high-performance and optimized to use eco-friendly media. PostProcess provide media in 50 pound plastic containers with molded-in handles, for easy unload and storage. The media has been formulated and tested to have the lowest attrition rates in the industry.

Why you need a NITOR Surface Finishing Machine

3 Advantages of using an automated Surface Finishing Solution for 3D printed parts

1. Consistent Results

It is virtually impossible to achieve uniformity on every part with manual finishing. PostProcess automated surface finishing ensures that every part is identical, every time — to your specification with the precise Ra required.

2. Reduced Finishing Time

PostProcess harnesses extensive engineering expertise applied to surface finishing of numerous printed parts in the same batch and at faster speeds than manual processing. Ensuring that post-print finishing never hinders the production runs.

3. Greater Productivity

The PostProcess NITOR Surface Finishing machine can work on numerous printed parts simultaneously. Enabling companies to focus on higher-value activities.
