The Polish SLS printer manufacturer Sinterit is expanding its portfolio with a key post-processing technology: in collaboration with the British company AMT, Sinterit now offers vapor smoothing as part of fully configurable post-processing systems. The aim is to realize an end-to-end workflow for selective laser sintering – from powder processing to the ready-to-use component.
Vapor Smoothing, a chemical smoothing technology, improves the surface roughness, mechanical properties and impermeability of polymer-based 3D printed parts. The treatment allows porous structures to be sealed, which is essential for applications in medical technology, food processing and hygiene, among others.
“At Sinterit, our focus from the start has been to make high-performance SLS 3D printing truly accessible to professionals across industries. As the market evolves, so do our customers’ expectations—they demand not just quality prints, but reliable, end-use parts. To support that, we’ve partnered with AMT—a proven, experienced player whose solutions have already been validated across industrial environments. Their technology enables our users to explore entirely new applications and raise the bar for what’s achievable with SLS. By combining Sinterit’s accessible yet powerful printing systems with trusted AMT’s post-processing capabilities, we offer a complete solution—from print to finished part—designed to meet the real-world needs of modern professionals”, said Maksymilian Wikar, Sinterit Sales Director.
In addition to Sinterit’s compact LISA X and SUZY SLS printers, the new system solution also includes AMT’s PostPro SFX and the optional PostPro DPX depowdering unit. The set is aimed at users with high demands on quality, process control and series maturity. Thanks to its modular configuration, the package is suitable for both research laboratories and small industrial series.
Application examples range from orthopaedic aids with optimized impact resistance to food contact parts with sterilizable surfaces and functional components for the automotive industry. According to AMT, one OEM was able to avoid the failure of over 30,000 vehicles thanks to temporary production with smoothed SLS parts.
“At AMT, we’re excited to partner with Sinterit to bring seamless, end-to-end post-processing solutions to SLS 3D printing. Together, we’re unlocking new levels of efficiency, surface quality, and scalability—empowering innovators to go from prototype to production faster than ever”, said Paul Carlson, AMT Chief Commercial Officer.
The complete solutions are now available through Sinterit’s international partner network and are designed to further lower the barrier to industrial adoption of additive manufacturing.
