What AMT publishes

  • Chamber: double the chamber capacity of the SFX. For exact dimensions, see the SF2X product page.
  • Cycle: 2 hours.
  • Consumable: PostPro Pure (FA5802).
  • Technologies: MJF, SLS, HSS; FDM ULTEM and Onyx parts.
  • Internal surfaces: the SF2X page notes that the process also seals internal cavities, improving strength, durability and chemical resistance while preserving dimensional accuracy.

In Europe, Raise3D offers the SFX and SF2X alongside its SLS printers, through a partnership announced in April 2026.

    SF50 or SF100? The same machine with two chamber sizes

    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.
