# PostPro SF50. Built for low-volume production.

PostPro SF50 is AMT's automated, industrial vapor smoothing system for low-volume production of end-use parts. It shares the SF100 cabinet and controls, with a smaller 50 L chamber.[1,2] An automated cycle of up to 2 h, with a choice of three finishing agents.[2,3]

- **Chamber**: 50 L[2]
- **Cycle**: up to 2 h[2]
- **Weight**: 800 kg[1]

## One cycle, start to finish.

Parts load from the front at an ergonomic height. Vapor generation, recovery and drying run inside one closed loop.[1,2]

1. ### Conditioning

   Parts are conditioned in the chamber to reach the right processing conditions.
2. ### Processing

   Vaporized consumable is injected into the chamber and smooths part surfaces under controlled conditions.
3. ### Curing

   The consumable is removed from the surface and the surface resolidifies.
4. ### Drying

   Parts are dried so no consumable remains in the chamber, ready for use.
5. up to 2 h[2]

   One cycle, all four stages

The four stages of one PostPro cycle.[2]

### Materials

- **Chamber**: 400 × 300 × 400 mm (50 L)
- **Loading**: Front-loading chamber at an ergonomic height
- **Printers**: MJF, SLS, SAF, HSS; FDM (including Ultem, Onyx, ABS and ASA)[1,2,3]
- **Materials**: PA12 · PA11 · TPU · TPE · PP (FA9202) · FDM (Ultem, Onyx, ABS, ASA); 100+ thermoplastics with FA326 on SF50 and SF100[1,2,3]

## 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.[1] The closed loop recovers the consumable for the next cycle.[2]

## PostPro SF50 questions.

[Ask an engineer](https://amtechnologies.com/contact-us/?topic=engineer&for=SF50#engineer)

### What is the PostPro SF50?

An automated, industrial vapor smoothing system by AMT (Additive Manufacturing Technologies), sized for low-volume production of end-use parts. It finishes 3D printed polymer parts in a 400 × 300 × 400 mm process chamber, in an automated cycle of up to 2 h.[2]

### How is the SF50 different from the SF100?

Both share the same 830 × 1400 × 1830 mm[1] 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).[2]

### Which parts and materials can the SF50 smooth?

Parts from MJF, SLS, SAF, HSS; FDM (including Ultem, Onyx, ABS and ASA)[1,2,3] printers, in PA12 · PA11 · TPU · TPE · PP (FA9202) · FDM (Ultem, Onyx, ABS, ASA)[1,2,3]. Three finishing agents are available: FA5802 (Pure) · FA326 · FA9202[2,3].

### 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;[8] 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.

### What does the SF50 need on site?

Three-phase power (Three-phase, 400 V or 480 V, 50/60 Hz; EU: L1+L2+L3+N+PE · US: L1+L2+L3+PE), a 830 × 1400 mm footprint and a recommended operating area of 2350 × 3200 mm.[1] Compressed air, extraction and network requirements come with your installation pack: [request installation requirements](https://amtechnologies.com/contact-us/?topic=engineer&q=Please+send+the+installation+requirements+for+the+PostPro+SF50.&for=SF50#engineer)

### Can I test my parts before I buy?
