One cycle, start to finish.
Parts load from the front at an ergonomic height. Vapor generation, recovery and drying run inside one closed loop.
Conditioning
Parts are conditioned in the chamber to reach the right processing conditions.
Processing
Vaporized consumable is injected into the chamber and smooths part surfaces under controlled conditions.
Curing
The consumable is removed from the surface and the surface resolidifies.
Drying
Parts are dried so no consumable remains in the chamber, ready for use.

Built for your floor.
The SF50 brings the SF100's production cabinet to smaller runs. Parts load from the front at an ergonomic height, an HD touchscreen runs the cycle, and MES/ERP connectivity links it to your line. The closed loop recovers the consumable for the next cycle.

How is the SF50 different from the SF100?
Both share the same 830 × 1400 × 1830 mm cabinet, the same controls and the same automated cycle of up to 2 h. The SF50's process chamber is 400 × 300 × 400 mm (50 L); the SF100's is 400 × 600 × 400 mm (100 L).
Which parts and materials can the SF50 smooth?
Parts from MJF, SLS, SAF, HSS; FDM (including Ultem, Onyx, ABS and ASA) printers, in PA12 · PA11 · TPU · TPE · PP (FA9202) · FDM (Ultem, Onyx, ABS, ASA). Three finishing agents are available: FA5802 (Pure) · FA326 · FA9202.
How much does the PostPro SF50 cost?
The SF50's starting price is in the Price chapter on this page, excluding tax and shipping. Every SF50 is supplied with the PostPro SF50 Ancillaries Pack, and installation, remote or on site, is part of every order; your quotation prices them with the machine, with training and the care pack you choose: RemoteCare (standard tier) or HyperCare (premium tier), for one, two or three years.
