SMOOTHING

Explore our range of cutting edge vapor smoothing machines for 3D printing and beyond. 

INTRODUCTION

What is vapor smoothing?

3D printed parts are not end-use ready when they come off the printer. The rough and porous surface of as-printed parts limits their use cases and functionality. Vapor smoothing is a vital step in 3D printing post-processing in that it turns parts into smoother, more functional, and aesthetically appealing finished products.

THE PROCESS

How does vapor smoothing work?

Vapor smoothing is a finishing process in which the rough surface of a printed object is exposed to solvent vapors under controlled conditions. The vapor condenses on the part’s surface, eliminating peaks and troughs, and enhancing the part’s strength, aesthetics, and water resistance. This results in a smooth and professional appearance.

RECIPE SELECTION

The parameters are selected based on the characteristics of the geometry and material. The process starts automatically after the recipe is selected.

PART PROCESSING

The vaporized solvent is injected in the processing chamber, evenly smoothing part surfaces under controlled conditions.

PART DRYING

The parts are resolidified and dried, ensuring that no solvent traces remain on the the surface. The parts are ready for their end use application.

FAQ

ask us
anything

Our vapor smoothing systems are capable of smoothing a wide range of thermoplastic polymers, encompassing rigid plastics, elastomers, and composites. However, thermosets are not currently supported

The parts should be free of powder and are ideally depowdered using an automatic depowdering system, such as the PostPro DP, DP PRO, or DP MAX. There are no other requirements

Parts can be dyed either before or after the smoothing process, depending on your workflow. If you are smoothing HP MJF grey parts, vapor smoothing removes the semi-sintered layer of the part, revealing the material’s vibrant black color. In this scenario, dyeing the part black may be unnecessary. 

Certainly, we provide complimentary benchmarking services to demonstrate the impact of vapor smoothing on your own parts. For more details and to initiate the process, please reach out to us using the benchmarking form available on our website.
