The AMT PostPro SF2X is a desktop vapor smoothing system engineered for scalable 3D post-processing workflows, housing a 24.4 L process chamber — precisely double the capacity of its SFX predecessor — within a compact bench-top enclosure of 450 × 500 × 845 mm. Validated on over 30 million parts and protected under three AMT patents, it processes PA12, PA11, TPU, ULTEM, and ONYX from MJF, SLS, HSS, SAF, and FDM platforms using PostPro Pure closed-loop biodegradable solvent, with batch cycle times between 30 and 120 minutes.

Double the Capacity, Same Proven Performance
The SF2X builds directly on the PostPro SFX platform — a technology AMT has developed and refined over eight years, accumulating a validated production history of more than 30 million parts across print bureaux, medical device labs, and industrial R&D environments. The SF2X retains the identical smoothing chemistry, consumable format, and process quality of the SFX while expanding the process chamber to 24.4 litres: the natural throughput step-up for operations that have reached the ceiling of a single SFX unit without requiring a full industrial floor-standing system. Three AMT patents — EP3565712, GB2582225, and GB2597240B — protect the proprietary vapor smoothing process that distinguishes this approach from conventional chemical finishing methods.
The video below, produced by AMT, presents the SF2X platform design, its scalability proposition relative to the SFX, and the PostPro Pure chemistry workflow in detail. It is recommended viewing before configuring a first batch.
The front elevation view below shows the SF2X in its operating configuration, door open, to illustrate the depth of the 250 × 390 × 250 mm processing cavity. The compact 450 mm external width allows the unit to occupy a standard laboratory bench module alongside other post-processing equipment.
PostPro Pure: Closed-Loop Green Chemistry
Every SF2X cycle draws from PostPro Pure, AMT's proprietary solvent delivered in safe-pour, non-hazardous cartridges. The closed-loop process continuously condenses, recovers, and reuses solvent vapour within the sealed chamber — no open solvent bath, no direct operator exposure during processing, and no requirement for specialist hazardous-materials storage beyond the cartridge format itself. The FA5802 cartridge system reduces consumable management to a straightforward, tool-free swap between batches.
PostPro Pure carries a comprehensive independent certification portfolio relevant to regulated production environments. Cytotoxicity tests under ISO 10993-5:2009 (with companion standards ISO 10993-1:2010, 10993-12:2012) confirmed no cytotoxic effect on processed parts. The solvent is rated non-sensitizing to humans under EC No. 1272/2008, classified readily biodegradable per OECD Guideline 301B, and shows no short-term toxicity to aquatic invertebrates (OECD 202) or to aquatic algae and cyanobacteria (OECD 201). For food-adjacent and medical applications, PostPro Pure is listed in the FDA-approved database and complies with food-contact regulations EG 1935/2004, EU 10/2011, and EG 2023/2006, validated on HP MJF PA12 and SLS PA2200. REACH (EC 1907/2006) and RoHS (2011/65/EU, amendment 2015/863) compliance is confirmed.
The workshop scene below positions the SF2X in context — a production-grade additive manufacturing environment with 3D printed polymer components arranged in the foreground, conveying the bench-top integration that characterises the system in daily use.
Surface Sealing and Part Performance: What the Chemistry Actually Does
Vapor smoothing is not a coating applied from the outside — it is a controlled polymer reflow triggered at the molecular surface layer. PostPro Pure vapour briefly plasticizes the outermost surface of the part, allowing surface tension to draw layer-line peaks and troughs into a continuous, sealed skin. The result is a measurably different component: lower surface roughness Ra, sealed external porosity, and — critically for functional applications — sealed internal cavities that no abrasive or mechanical finishing route can achieve from the exterior.
The sequence below documents this effect on a bellows-type TPU accordion component produced on a powder-bed system. The as-printed state shows the characteristic granular, matte-grey surface of SLS or MJF TPU output, with open surface porosity that prevents the part from passing any fluid-tightness evaluation.
After a single PostPro SF2X cycle, the same component emerges with a consolidated, dark semi-gloss surface. Layer-lines are no longer individually visible; surface porosity is sealed; and the part passes a water-tightness evaluation that the as-printed version would fail outright. Bulk material is not removed in this process — dimensional accuracy is preserved, with property changes reflecting the sealed surface state rather than any loss of base geometry.
Material and Technology Compatibility
The SF2X is a multi-material, multi-technology finishing tool. Its solvent chemistry is validated across the most commercially significant powder-bed and FDM thermoplastics: PA12 and PA11 from both MJF and SLS platforms, TPU for elastomeric and flexible applications, ULTEM for high-performance engineering requirements, and ONYX — Markforged's carbon-filled nylon composite — for FDM structural parts. Supported print technologies span MJF, SLS, HSS, SAF, and FDM/FFF. This breadth means a mixed-technology print room can route the majority of its finishing through a single SF2X unit rather than maintaining separate post-processing paths for each material platform.

What 3D printing technologies is the AMT PostPro SF2X compatible with?
The PostPro SF2X supports MJF, SLS, HSS, SAF, and FDM/FFF printed parts. Validated materials include PA12, PA11, TPU, ULTEM, and ONYX, covering the principal commercial powder-bed and engineering-grade FDM output types in current industrial use.
How long does a PostPro SF2X vapor smoothing cycle take?
Typical cycle time is 30 to 120 minutes per batch, depending on part geometry, material type, and target surface finish level. The 24.4 L process chamber accommodates multiple parts per run, so total throughput per hour is geometry- and material-dependent.
Is PostPro Pure solvent food-safe and biodegradable?
Yes. PostPro Pure is listed in the FDA-approved database and complies with food-contact regulations EG 1935/2004, EU 10/2011, and EG 2023/2006, validated on HP MJF PA12 and SLS PA2200. It is independently classified as readily biodegradable under OECD Guideline 301B, with no observed short-term toxicity to aquatic organisms.
How does the SF2X differ in capacity from the PostPro SFX?
The PostPro SF2X provides exactly twice the process chamber volume of the SFX at 24.4 litres, within a similar external bench-top footprint. Smoothing chemistry, PostPro Pure cartridge format, and cycle parameters remain identical across both platforms, making the capacity upgrade operationally seamless.
Does vapor smoothing affect part dimensional accuracy?
The PostPro vapor smoothing process reflows only the surface molecular layer of the part — it does not remove bulk material. Dimensional accuracy is preserved; the process eliminates surface asperities and seals both external and internal porosity, delivering a functional improvement without measurable loss of base geometry.
