TUMBLING
SMOOTHER SURFACES FOR ADDITIVELY MANUFACTURED PARTS
Additively manufactured parts typically have a characteristic surface roughness after production.
Tumbling is a mechanical post-processing process used to reduce this roughness and create a smoother, more uniform surface.
CIPRES uses tumbling as a finishing process for suitable additively manufactured polymer parts and as preparation for subsequent finishing steps.
HOW DOES TUMBLING WORK?
During tumbling, the components are processed together with specially selected media in a finishing system.
The controlled movement between the parts and the media gradually reduces surface roughness and smooths the component surface.
The process parameters are adapted to the material, component geometry and required surface quality.

IMPROVED SURFACE QUALITY
Tumbling can significantly improve the visual appearance and feel of additively manufactured parts.
Depending on the component and process parameters, the treatment can:
- Reduce surface roughness
- Create a smoother and more uniform surface
- Improve the visual appearance of the component
- Improve the feel of the surface
- Prepare parts for subsequent finishing processes
PREPARATION FOR FURTHER FINISHING
Tumbling can be used as a standalone finishing process or combined with additional surface treatments.
Depending on the material and application, subsequent processes can include:
- Dyeing
- Chemical smoothing
- Infiltration
- UV protection
- Painting
This allows different finishing steps to be combined according to the required final result.
TYPICAL APPLICATIONS
Tumbling is suitable for a wide range of additively manufactured components, including:
- Functional parts
- Housings and covers
- Technical components
- Small and series production parts
- Eyewear
- Design products
- Parts with visual surface requirements
SURFACE LEVELING OR TUMBLING?
The appropriate process depends on the initial surface and the required result.
Surface leveling is primarily used to clean, prepare and create a more uniform surface.
Tumbling provides more intensive mechanical surface treatment and is used to reduce surface roughness and create a smoother finish.
Depending on the component, both processes can also be combined with additional finishing steps.
YOU PRINT – WE FINISH.
Your parts do not have to be manufactured by CIPRES.
If you produce your components in-house or source them from another additive manufacturing provider, you can send them directly to CIPRES for tumbling and further surface finishing.
IS TUMBLING SUITABLE FOR YOUR PART?
