VaporFuse Smoothing Technology
VaporFuse smoothing is an advanced vapor finishing process designed to improve the surface quality, durability and sealing performance of SLS 3D printed parts. By chemically smoothing the outer surface of nylon components, VaporFuse technology reduces porosity, improves appearance and enhances mechanical performance.
This process is widely used in industrial 3D printing applications where functional performance, chemical resistance and high-quality surface finish are required. VaporFuse smoothing is particularly effective for SLS printed nylon parts used in automation, robotics, medical devices and consumer products.
The first-ever green vapor polishing solution for highly industrial manufacturing and surface improvements of 3D Printed parts. This technology enables endless application possibilities for Nylon 12 parts manufactured by Additive Manufacturing in industries such as automotive, medical & chemical tech, Automation and Robotics, consumer goods & prototyping. The sustainable Vapor Fuse Eco Fluid is 100% bio-based and readily biodegradable as well as non-toxic: no PFAS, no CMR, no PvM/PMT.
Watch how Vapor Fuse Smoothing seals surfaces, improves durability, and delivers injection-molded quality for industrial 3D printed parts.
KEY BENEFITS OF VAPOR FUSE SMOOTHING
Smooth, Injection-Molded-Like Surfaces
Vapor Fuse Smoothing significantly lowers surface roughness, often by more than 70 percent, creating a clean and uniform finish comparable to injection molded parts.
Sealed, Water-Tight, and Airtight Performance
The vapor smoothing process fully seals both internal and external surfaces, preventing water absorption and reducing air or fluid leakage in functional parts.
Improved Appearance and Surface Feel
Treated parts feature a consistent, glossy surface that enhances visual quality while making components easier to clean and maintain in daily use.
Increased Mechanical Durability
By improving elongation at break by up to 200 percent, Vapor Fuse Smoothing enhances part toughness and resistance to repeated mechanical stress.
Approved for Food Contact Applications
The bio-based solvent used in the process complies with Regulation (EU) 10/2011, enabling the use of 3D printed parts in food handling and packaging environments.
This compliance is based on technical data provided by DyeMansion, the developer of Powerfuse S technology.

Reduced Risk of Bacterial Contamination
Sealed and non-porous surfaces limit bacterial buildup, making vapor-smoothed parts suitable for medical, food, and hygiene-sensitive applications.
Optimized Flow in Internal Channels
Smoother internal geometries reduce friction, allowing more efficient airflow or fluid movement in parts with channels, ducts, or piping features.
High Dimensional Stability
Surface refinement is achieved without compromising accuracy, with dimensional variation typically remaining below 0.4 percent of the original design.
Engineered for Industrial Performance
Why VaporFuse Smoothing Matters
Surface quality is no longer just cosmetic. In automation, food processing, and medical environments, it directly impacts performance, hygiene, and reliability. Vapor Fuse Smoothing seals porous 3D printed surfaces, making parts water-tight, easier to clean, and suitable for demanding production environments.
