PostPro Chemical Vapor Smoothing
Fully automated surface finishing technology that smooths and seals the surface of 3D printed polymer parts. Achieving a surface finish with an injection molded look and feel. The process is non-line-of-sight and therefore can smooth complex geometries and internal cavities of thermoplastic parts without degrading the mechanical properties. Combined with UL & CE certification, the patented PostPro vapor smoothing technology is recommended by the world leading additive manufacturing players.

POSTPRO SF50
PostPro SF50 is a patented chemical vapor smoothing solution for post-processing thermoplastic 3D printed parts. Formerly known as PostPro3D MINI, this new generation technology includes advanced features providing a more efficient user and production experience.
Designed for prototyping and low volumes, the PostPro SF50 offers a 50 liter chamber for quick and efficient post-processing of prototypes and a series of smaller part sizes. Ideal for research and development, as well as design and production activities.
POSTPRO SF100
The PostPro SF100 is AMT’s next generation chemical vapor smoothing technology that sets new benchmark gold standards for the AM industry.
The PostPro SF100 was designed for high volume production with a processing chamber of 100 liters.
Its compact and ergonomic form allows easier operation while taking up less valuable operating floor space.
The PostPro SF100 takes your parts performance to the next level. By enhancing your surface, not only does it create beautifully looking parts, but it also improves the mechanical performance and seals the surface enabling easy cleaning, dyeing, and coating, while keeping dimensional accuracy without marks from fixtures.

Performance Enhancements

Increased Mechanical Properties
Due to the removal of surface porosity and crack initiation sites, extensive testing demonstrates that vapor smoothed parts result in an increase of Elongation at Break (EAB) with no loss in ultimate tensile strength.

Enhances Color Vibrancy
An added value is that colored parts do not bleed in the vapor smoothing process. Instead, color consistency and hue are enhanced, making them more vibrant.

Injection Molded Surface Quality
Using a series of predefined parameters, our chemical vapor smoothing achieves for the first time a surface finish that matches injection molding techniques with an RA of less than 1 micron.
System Compatibility
AMT's technologies have been developed to process thermoplastic polymer materials. Currently the technology can process Polyamide (Nylon) (6,11,12), Flame retardant Nylons, Carbon/Glass filled derivatives of Nylons, ULTEM, PMMA, Thermoplastic polyurethane (TPU), and Thermoplastic Elastomers (TPE).
