PA12, PA11 and TPU with FA5802 (Pure), Polypropylene (PP) with FA9202, and FDM parts in Ultem and Onyx.[1,6,11] Printing processes: MJF, SLS, SAF, HSS; FDM (Ultem, Onyx)[1,5]. Not on the list? Send a part to the free benchmark. ### What does the SFX need to run? A bench for a 450 × 500 mm footprint and 82 kg, and single-phase power: 230 V single-phase, 16 A or 13 A (UK) · 120 V single-phase, 15 A (US). No external extraction system is required.[2] ### How long does a cycle take? up to 2 h for the full automated cycle of conditioning, processing, curing and drying.[1] ### Should I choose the SFX or the SF2X? Both run the same process, with the same Pure chemistry and the same automated cycle of up to 2 h. The SF2X has a 260 × 390 × 260 mm chamber, double the SFX capacity.[1,14] [PostPro SF2X](https://amtechnologies.com/products/vapor-smoothing/postpro-sf2x/) ### Can I test my parts before I buy? Yes.
