PostPro SFX Desktop


Desktop Vapor Smoothing System

The world’s first bench-top vapor smoothing system, utilizing our cutting-edge green chemistry, PostPro Pure. Compatible with engineering plastics, the system produces a high quality vapor smoothed surface finish even in office environments.

What is vapour smoothing and why do you need it?

Vapor smoothing for 3D printing is a process in which additively manufactured parts are exposed to a vapor under carefully controlled conditions. This non-line-of-sight approach creates parts with a smooth surface, improved mechanical performance, sealed and sterilizable surfaces. This innovative technology opens a world of new application opportunities in industries such as medical, automotive, food & beverage and consumer goods.

Plug & Play

Simple and fast installation with a small footprint, enabling operation in an office environment.

Compact & Versatile

Designed for R&D and low-volume prototyping projects. Suitable for a range of engineering plastics.

Safe & Green Chemistry

The system utilizes PostPro Pure in quick-change cartridges, for safe and hassle-free operation.

AMT Patented Technology

Drawing on AMT’s 6 years professional experience in the chemical vapor smoothing industry. Protected under the following patents: EP3565712, GB2582225 & GB2597240B.

Enhancing Part Properties

The only technology that smooths and seals the surface and internal cavities of 3D printed polymer parts, while also improving mechanical properties.

TUP LITE Software

The SFX interface is designed for maximum user-friendliness. The operator inputs the thickness of the part, the fill level of the processing chamber, as well as the part characteristics. Following a quick visual inspection, the user is able to input all of the parameters and start the vapor smoothing process.

Unlimited Applications

Optimized for rigid thermoplastics, with an expanded material compatibility on the horizon. Ideal for SLS, MJF, HSS and FFF applications.

What Can You Expect?

The vapor smoothing process reduces the surface roughness of the part, enhances the material's mechanical properties, such as elongation at break and tensile strength, and seals the surface against liquids. View the before and after photos to know what you can expect:
