Vapor Smoothing
Scalable vapor smoothing for production-ready MJF parts
Vapor smoothing is a post-processing method that refines the surface of Multi Jet Fusion (MJF) parts by reducing surface texture and creating a more uniform finish. It is commonly used when parts need a more production-like look and feel, or when surface sealing and cleanability are important.
In addition to improving cosmetics, vapor smoothing helps “close” surface porosity so parts are easier to wipe down and less likely to hold residue in textured areas. That sealed surface also creates a better foundation for downstream finishing steps like dyeing and coatings, especially when you need consistent results across a batch.
Why Teams Use Vapor Smoothing for End-Use Parts
Vapor smoothing is often chosen when a part needs to function and present more like a production component, especially for customer-facing products and applications that involve repeated handling, cleaning, or environmental exposure. It can also reduce finishing variability by creating a more consistent surface across complex geometry.
Common Outcomes Include:
- A smoother, more uniform surface finish
- Improved surface sealing for easier cleaning and handling
- More consistent results when dyeing or coating
- Higher cosmetic readiness for consumer-facing applications
Should You Vapor Smooth Your MJF Part?
Vapor smoothing is not required for every MJF build, but it is a strong choice when end-use requirements go beyond basic function. If the part will be handled frequently, needs to be cleaned regularly, or must look and feel more polished, smoothing can be the difference between a part that reads as “printed” and one that reads as production-ready. It is also a smart step when you need more consistent finishing outcomes across a batch, especially on complex geometry where natural surface texture can vary by orientation and feature detail. For teams planning downstream finishing, vapor smoothing can improve reliability by creating a more uniform surface foundation for dyeing and coatings, which helps parts match better from run to run.
Use the guide below to decide quickly:
Yes, consider vapor smoothing if:
- You need sealed or cleanable surfaces
- The part will see repeated handling, exposure to dust or moisture, or routine wipe-down cleaning
- You plan to dye or coat parts and want more consistent, uniform results
- The part is consumer-facing and surface feel and appearance matter
Maybe not, if:
- Surface texture is acceptable for the application
- The part is primarily internal or functional and finish quality is not a priority
- You are optimizing strictly for cost and the natural MJF finish meets requirements
