System of Alisado por Vapor - AMT PostPro SFX

Main Features and Operation

The PostPro SFX by AMT Technologies is the world’s first desktop chemical vapor smoothing system, specifically designed for post-processing 3D printed parts using SLS, MJF, HSS, and FDM/FFF technologies. This compact, plug-and-play solution transforms polymer parts into industrial-grade components with smooth, sealed, and durable surfaces.

The unit has external dimensions of 450 x 500 x 845 mm and a weight of 82 kg, allowing integration even in compact workspaces. Its processing chamber has a volume of 11.5 liters and internal dimensions of 190 x 320 x 190 mm, enabling the simultaneous treatment of multiple parts. The smoothing process, which takes approximately two hours, is performed with the eco-friendly and non-toxic PostPro Pure consumable, developed by AMT and approved by the FDA, ensuring a uniform and safe finish without compromising environmental sustainability.

The PostPro SFX features an intuitive software, Wi-Fi and Ethernet connectivity for remote support, and a 7-inch touchscreen that facilitates control of all operating parameters. Unlike more complex systems, it does not require an external extraction system or additional installations, making it a versatile, efficient, and high-quality solution for labs, R&D centers, and low-volume production lines.

The vapor smoothing range from AMT Technologies also includes two other systems: the SF50 and SF100.

Case Studies and Industrial Applications

The PostPro SFX vapor smoothing system has been successfully implemented in demanding sectors such as medical, automotive, consumer goods, and food, where surface quality, hygiene, and mechanical strength are critical factors for end-use 3D printed parts.

In the healthcare sector, PostPro SFX treatment has allowed specialized companies to significantly improve the biocompatibility of medical components printed using SLS and MJF. The ability to seal pores, smooth surfaces, and eliminate crack initiation points has been key to complying with the strictest regulations in surgical, orthopedic, and prosthetic applications.

A particularly innovative case is that of FABULOUS, a leading company in certified material development for 3D printing in food environments. In collaboration with food production line manufacturers, FABULOUS designed functional components like strainers, scrapers, and nozzles using their material Bluecare: a blue PA11 powder, certified for food contact according to EU and FDA regulations. The challenge was to seal and smooth these SLS-printed parts, minimizing surface roughness to prevent bacterial proliferation. The PostPro SFX system achieved smooth, easy-to-clean finishes and enhanced the blue color intensity for optimal visual detection, improving food safety and quality control efficiency.

Another notable example is the project developed by Conductr, a company specializing in digital technology for interactive gaming, which needed to quickly produce 80 custom disc covers for its digital shuffleboard table. The complexity of the design, specific color patterns, and a tight delivery deadline made injection molding unfeasible. The solution was implemented by PrintCity, the innovation center of the Manchester Metropolitan University, which used HP MJF 3D printing and AMT PostPro SFX post-processing. In less than a week, the final parts were delivered with a smooth, functional, and visually appealing finish. This collaboration demonstrated how vapor smoothing enables the production of durable, high-quality consumer components, even in short runs with advanced aesthetic requirements.
