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:

Selective laser sintering (SLS)
Fused deposition modeling (FDM)

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:

Clear, glossy, optical-grade surfaces
No layer lines and surface imperfections
Improved part integrity and durability
Repeatable, automated results
Zero regulatory exposure under the Toxic Substances Control Act (TSCA) DCM restrictions
