The short version

  • Only Formlabs PreForm has a free tier, so it costs nothing to try first.
  • Each has a real cost: Autodesk Netfabb netfabb Ultimate has been retired outright, with no 2026 release and no renewals, so anyone who bought Ultimate is frozen on the 2025.1 build and must accept the repackaged Netfabb instead.; Formlabs PreForm preForm only drives Formlabs printers, so the free software is really an entry cost to a closed hardware and resin ecosystem rather than a tool you can keep if you change machines.
  • They diverge on capability: Autodesk Netfabb covers Mesh repair, Formlabs PreForm covers Automatic orientation.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Autodesk Netfabb

  • Netfabb Ultimate has been retired outright, with no 2026 release and no renewals, so anyone who bought Ultimate is frozen on the 2025.1 build and must accept the repackaged Netfabb instead.
  • Autodesk has ended development of the Selective Space Structures, Optimization Utility and Lattice Topology utilities, which removes capability some customers specifically bought the product for.
  • It is now only sold bundled as Autodesk Fusion with Netfabb, so a shop that has standardised on other CAD pays for Fusion entitlements it will not use.
  • At around 4,415 US dollars per seat per year it is far above slicer-class tools, and the pricing is per named user with no floating option in the standard subscription, which hurts teams where the AM engineer role is shared.
  • Machine coverage is broad but not universal, and the newest printers from smaller manufacturers often reach their vendor own preparation software long before a Netfabb profile appears.

Formlabs PreForm

  • PreForm only drives Formlabs printers, so the free software is really an entry cost to a closed hardware and resin ecosystem rather than a tool you can keep if you change machines.
  • Formlabs resin is sold in proprietary cartridges, and the ongoing consumable cost over a printer's life dwarfs anything a paid slicer would have charged.
  • Third-party resins can be used only through open material settings that step outside validated profiles, which affects print reliability and the comfort of warranty support.
  • Parameter-level control is deliberately limited compared with open slicers, so advanced users cannot tune exposure and layer behaviour the way they can on an open platform.
  • It is Windows and macOS only with no Linux build, which is awkward for research groups and labs standardised on Linux workstations.

Answered from the vendors’ own pages

Autodesk Netfabb: Is Netfabb discontinued?

No, but Netfabb Ultimate is. There is a 2026 release of Netfabb, sold only as Autodesk Fusion with Netfabb. Ultimate licences cannot be renewed.

Formlabs PreForm: Is PreForm free?

Yes, with no licence fee, subscription or installation limit. It is free because it only prepares jobs for Formlabs printers.

Autodesk Netfabb: What does it cost?

The Fusion with Netfabb single-user subscription is listed at roughly 4,415 US dollars a year. Netfabb Simulation is quoted separately.

Formlabs PreForm: Can PreForm drive a non-Formlabs printer?

No, and it never will. It is the front end for Formlabs hardware, which is where the revenue is.

Autodesk Netfabb: Is there a perpetual licence?

No. Autodesk sells subscription only across its product range.

Formlabs PreForm: Can I use third-party resin?

Only via open material settings, which take you outside validated profiles and the reliability those profiles are tuned for.

Autodesk Netfabb: Do I need Fusion to use it?

You do not have to use Fusion, but you now pay for it, because the bundle is the only way Netfabb is sold.

Formlabs PreForm: Does it run on Linux?
