Vapor smoothing

Vapor smoothing is an advanced finishing process that significantly improves the surface quality of 3D printed components. At Yicen Machining, we use controlled solvent vapor exposure to transform rough, layered prints into smooth, glossy parts with a high-end, injection-molded look.

This technique is ideal for enhancing both the function and appearance of parts made from FDM, SLS, and MJF technologies perfect for prototypes and production-ready products alike.

How It Works?

Vapor smoothing involves placing parts in a specialized chamber where vaporized solvents are introduced. These vapors slightly melt the outermost layers of the material, softening sharp textures and smoothing rough layer lines. Once the solvent is purged, the part re-solidifies with a uniform, sealed finish.

The entire process is monitored to ensure no distortion while achieving consistent results across all surfaces.

Advantages of Vapor Smoothing

Yicen Machining recommends vapor smoothing for any application requiring:

• Aesthetic upgrades without mechanical compromise
• Elimination of visible 3D print layering
• Improved airflow or fluid dynamics
• Surfaces that are easier to sanitize
• Pre-finishing for painting or coating

This finishing option provides both a cosmetic boost and functional benefits, especially in parts that interact with users or liquids.
