What is Vapor Smoothing?<\/h3>\n\n\n\n

Parts are placed in a controlled vacuum chamber where a specialized vaporized agent circulates. This agent interacts with the outer “skin” of the polymer, allowing the surface material to redistribute and flow into the microscopic “valleys” of the part. A perfectly sealed surface that is both smooth and semi-glossy. Because this is a gaseous process, it reaches every internal channel and complex lattice structure with total uniformity.<\/p>\n\n\n\n

Fluid and Airtight Sealing<\/h3>\n\n\n\n

By fusing the surface pores, parts become naturally waterproof and airtight \u2014the gold standard for manifolds, tanks, and ducting.<\/p>\n<\/div>\n\n\n\n

\n

Enhanced Hygiene<\/h3>\n\n\n\n

By removing the surface porosity, bacteria and contaminants have no place to harbor. This makes the process essential for Medical and Food-Contact applications.<\/p>\n\n\n\n

Mechanical Ductility<\/h3>\n\n\n\n

The vapor-phase refinement can improve elongation-at-break, making parts slightly more flexible and resilient compared to raw prints.<\/p>\n\n\n\n

Internal Channel Refining<\/h3>\n\n\n\n

Unlike mechanical finishing, the gas reaches deep inside complex internal geometries that physical media cannot touch.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n

Surface roughness and dimensional impacts are based on standard industrial benchmarks for SLS PA 2200 & MJF PA 12 materials. It is important to note that final results are highly dependent on part geometry and wall thickness. For elastomeric materials such as SLS TPU, the vapor-phase process can lead to a more pronounced <\/strong>dimensional shrinkage compared to rigid polymers. Maximal part size is dependable on geometry.<\/p>\n\n

The Ultimate Duo<\/h3>\n\n\n\n

For projects where aesthetic appeal and functional performance are equally critical, combining DeepDye Coloring and Vapor Smoothing delivers a result that is indistinguishable from traditional manufacturing.<\/p>\n\n\n\n

While DeepDye Coloring provides rich, consistent color, the Vapor Smoothing process acts as the ultimate “amplifier.” By sealing the surface and reducing roughness to sub-micron levels before or after the coloring stage, we achieve:<\/p>\n\n\n\n
