# AMT PostPro

> AMT (Additive Manufacturing Technologies) provides automated surface finishing for 3D printed parts: PostPro vapor smoothing systems and consumables. AMT invented automated vapor smoothing for industrial 3D printing. PostPro systems seal and smooth powder-bed 3D printed polymer parts inside and out in one automated cycle (Conditioning · Processing · Curing · Drying). The range: the desktop PostPro SFX and SF2X, the floor-standing PostPro SF50 and SF100, PostPro Pure, FA326 and FA9202 consumables, and DMS automated loading for the SF100. Born from University of Sheffield research; founded in Sheffield, United Kingdom, in 2017.
