We get this question a lot. The short answer: the PostPro SF50 and SF100 are the same machine. The difference is the chamber. The SF50 page describes it as having the same benefits as the SF100, with a more compact processing chamber for smaller production runs and prototyping.

| | PostPro SF50 | PostPro SF100 |
| --- | --- | --- |
| Chamber | 400 × 300 × 400 mm | 400 × 600 × 400 mm |
| Cycle | 1.5–2 h | 1.5–2 h |
| External size | 830 × 1400 × 1830 mm | 830 × 1400 × 1830 mm |
| Consumable canister | 10 L | 10 L |
| Sized for | Low-volume production | High-volume production |

Both have RFID access, an HD touchscreen and MES/ERP connectivity, according to AMT’s brochure. Both run PostPro Pure, FA326 and FA9202 (see [PostPro Pure, FA326 or FA9202: which consumable for which material?](https://amtpostpro.discourse.group/t/postpro-pure-fa326-or-fa9202-which-consumable-for-which-material/53)).

## How to choose

- **Parts per run.** The SF100’s chamber measures 600 mm where the SF50’s measures 300 mm. If your parts or your weekly volume need that room, it is the SF100.
- **Automation.** Automated loading and unloading with DMS is for PostPro SF100 systems. See [Automated loading for the SF100: what DMS does](https://amtpostpro.discourse.group/t/automated-loading-for-the-sf100-what-dms-does/64).
- **Not sure?** [Send parts for a benchmark](https://benchmarking.amtechnologies.com/) and [talk to AMT](https://amtechnologies.com/contact-us/) about your volumes.

And for the desktop systems: the SFX and SF2X run 2 h cycles, and the SF2X has double the chamber capacity of the SFX.

**Over to you:** SF50 and SF100 owners, what decided it for you?
