Chemical Vapor Smoothing
PostPro Chemical Vapor Smoothing process is a physio-chemical process that can smooth a wide variety of thermoplastic polymers.
The process is non-line-of-sight and can smooth complex internal cavities of polymer parts.
PostPro vapor smoothing technology is highly controllable, allowing reproducible results with no degradation of a parts’ mechanical properties.
The process has been evolved from the PUSH process, developed at the University of Sheffield.
Benefits of PostPro Vapor Smoothing
Surface smoothing process that improves the part performance, seals the surface, and offers an injection molding look and feel. Combined with UL & CE certification, the patented PostPro vapor smoothing technology is recommended by the world leading additive manufacturing players.
PostPro vapor smoothing enhances performance and aesthetics of each part. Sealed surfaces are easier to dye, easier to certify for skin and food contact, while keeping dimensional accuracy without marks from fixtures.
Our throughput process allows for short cycle time, with perfect consistency from batch to batch. The large chamber size is ideal for high density of parts.
Ease of use, ease of maintenance and vast material compatibility creates accessibility for diverse applications and industries. Ergonomic, safe and UL & CE certified.

POSTPRO 3D MINI
Designed for prototyping and low volumes
With a 50 liter chamber, PostPro 3D MINI was developed for quick and efficient post-processing of prototypes and a series of smaller part sizes. Ideal for research and development, and design and production activities.
PostPro3D MINI offers all of the benefits of the PostPro 3D machine, just in a more compact unit.
Increased mechanical properties
Due to the removal of surface porosity, extensive testing demonstrates that vapor smoothed demonstrated no loss in Ultimate Tensile Strength (UTS) with an increase in Elongation at Break (EAB).
Injection molded surface quality
Using a series of predefined parameters, chemical vapor smoothing achieves for the first time a surface finish that matches injection molding techniques with an RA of less than 1 micron.
The process does not degrade the mechanical properties of the parts. After vapor smoothing, parts exhibit no more than a 0.4%-dimensional change irrespective of the desired finish level.
Seals against liquid & gas intake
The vapor smoothing process completely seals the surface, eliminating liquid or gas intake.
Vapor smoothing enhances the colour consistency and hue of coloured part. Additionally, parts that already have colour, such as HP MJF 580 parts, do not bleed in PostPro 3D machines.
Reduction in bacteria growth
Tests have shown the reduction of bacteria growth and attachment on parts that have been chemically vapor smoothed.
