Vapor Smoothing Post-Processing for Beautiful 3D Printing

Smooth your 3D printed parts to injection mold-like finishes using the AMT PostPro SF100 and SF50. These post-processing systems use a chemical polishing process that gives your parts a beautiful look while also improving color uniformity and, in many cases, sealing against water. These vapor smoothing machines can process parts from many different additive technologies, including:

The New Standard for Acrylic Finishing

When it comes to plastics like acrylic (also known as polymethyl methacrylate (PMMA)), chemical polishing with methylene chloride (also known as dichloromethane (DCM)) is often used to get smooth, transparent finishes. But, as of April 2026, the U.S. banned most industrial and commercial uses of methylene chloride.

The AMT PostPro SF100 Gen 2, combined with AMT PURE™ solvent technology, is fully compliant with U.S. Environmental Protection Agency (EPA) regulations and is a safer alternative to methylene chloride due to its fully enclosed, automated system.

It delivers high-quality vapor smoothing for acrylic 3D-printed parts, giving you:

Frequently Asked Questions

Yes, the equipment requires proper ventilation or exhaust systems in your facility.

The used chemical is extracted into canisters that are swapped out for new canisters by AMT. The user is not responsible for disposing of the chemical.

If you are running the PostPro SF100, a chiller unit and extractor are required to operate the system. An optional extraction system is recommended for use in addition to the PostPro SF50.

The PostPro SF100 and PostPro SF50 both use a closed-loop system so the user should never come into contact with the vapor smoothing chemical under normal operation.

Cycle times are 1 – 2 hours depending on the level of smoothness desired.

Yes, parts still need to be bead blasted before post-processing in these machines. Any powder that is not blasted can negatively affect the vapor smoothing process.
