The whitepaper explores the advanced capabilities of the PostPro® vapor smoothing technology, an automated post-processing solution designed to enhance the surface quality of 3D-printed thermoplastic polymer parts. This technology transforms rough,3D printed surfaces into smooth, sealed finishes comparable to injection-molded products, even on complex geometries that are difficult to process manually. PostPro® is the ideal finishing solution for users of systems like the Formlabs Fuse Series SLS printers.
The process leverages cutting-edge green chemistry and is compatible with a wide range of engineering plastics—including PA11, PA12, TPU, and PP—produced by powder bed fusion and extrusion-based printing methods.
The result is improved part functionality, aesthetics, and durability, making vapor smoothing a vital step in the 3D printing workflow for industries demanding high-quality finished products.
