Anything else, [ask an engineer](https://amtechnologies.com/contact-us/?topic=engineer&for=SF2X#engineer). ### What is the PostPro SF2X? The PostPro SF2X is AMT's desktop vapor smoothing system with double the chamber capacity of the PostPro SFX. It seals and smooths 3D printed polymer parts in a 260 × 390 × 260 mm chamber, in the same automated cycle of up to 2 h, with FA5802 (Pure).[1,2] ### How much does the PostPro SF2X cost? The SF2X starts from the price shown in the Price chapter on this page, excluding tax and shipping. It is sold as two bundles, the Starter Bundle and the Complete Bundle, with a machine stand and a preparation stand; your quotation prices the one you choose. [Request a quotation](https://amtechnologies.com/quote/?model=sf2x) ### How big is the chamber? 260 × 390 × 260 mm (W × D × H), 26.4 L, double the SFX chamber capacity.[1,2] How many of your parts fit per batch depends on racking, so an AMT application engineer confirms the load for your parts. ### Should I choose the SFX or the SF2X? Both run the same process with the same Pure chemistry, the same automated cycle of up to 2 h and the same 7-inch touchscreen.[1,3,9] The SFX has a 190 × 320 × 190 mm chamber; the SF2X doubles the capacity. [PostPro SFX](https://amtechnologies.com/products/vapor-smoothing/postpro-sfx-desktop-vapor-smoothing-system/) ### Which materials and printers does it work with? PA12, PA11 and TPU with Pure, and FDM parts in Ultem and Onyx.[1,2] Printing processes: MJF, SLS, HSS; FDM (Ultem, Onyx)[2]. For polypropylene, or a material not on the list, ask an engineer or send a part to the free benchmark. ### What power does it need? Single-phase power: 230 V single-phase, 16 A or 13 A (UK) · 120 V single-phase, 15 A (US)[3]. ### How big and heavy is the machine? The SF2X measures 510 × 540 × 920 mm (W × D × H) and weighs 106 kg, so plan a bench for a 510 × 540 mm footprint.[3] ### Can I test my parts before I buy? Yes.
