        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.

        What is Vapor Smoothing?

        3D printed parts are not end-use ready when they come off the printer. The rough and porous surface of as-printed parts limits their use cases and functionality. Vapor smoothing is a vital step in 3D printing post-processing in that it turns parts into smoother, more functional, and aesthetically appealing finished products.

        Available Vapor Smoothing Systems

        POSTPRO SFX

        The PostPro SFX is the world’s first desktop vapor smoothing system for engineering plastics.

        The desktop sized system does not only offer unparalleled post-processing performance – it has the smallest footprint, enabling smoothed, sealed and stronger parts in any environment. The PostPro SFX utilizes a green consumable, PostPro Pure.

        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.

        Results you can expect

        HP MJF PA11

        Vapor smoothing was used to enhance mechanical performance, establish a soft and biocompatible surface for interaction with children, and guarantee ease of cleaning through a sealed surface.

        HP MJF BASF Ultrasint® TPU01​

        The utilisation of this technology stemmed from the need for heightened durability, enabling its use across various conditions, as well as the desire for a biocompatible surface and impeccable finish, expected for a premium product.

        Performance Enhancements

        mech-prop

        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.

        inj-quality

        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.
