The short version

  • 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.; Flow Software the 11,390 dollar Starter licence caps at 250 measures and events, which a multi-line plant exhausts quickly once each line contributes a dozen calculations, forcing a jump to the 62,230 dollar tier.
  • They diverge on capability: Autodesk Netfabb covers Mesh repair, Flow Software covers Calculation engine.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

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.

Flow Software

  • The 11,390 dollar Starter licence caps at 250 measures and events, which a multi-line plant exhausts quickly once each line contributes a dozen calculations, forcing a jump to the 62,230 dollar tier.
  • The Unlimited licence requires every engine on a single server or VM, so any multi-server or multi-site topology goes straight to Distributed at roughly double the price with no intermediate option.
  • Maintenance renews at about fifteen percent of the installed base annually, so a large perpetual estate carries a five-figure recurring cost that the headline perpetual price hides.
  • It is a Windows product with a Microsoft data stack, so Linux or container-native deployment strategies do not apply and the server has to be managed on the plant Windows estate.
  • It calculates and reports but does not collect from equipment itself, so an existing historian or OPC layer is a prerequisite and Flow adds cost on top of that rather than replacing it.

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.

Flow Software: Does Flow publish real prices?

Yes. Starter is 11,390 USD perpetual for 250 measures, Unlimited is 62,230 USD perpetual or 16,595 USD a year, and Distributed is 128,450 USD perpetual or 34,250 USD a year.

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.

Flow Software: Is perpetual licensing still offered?

Yes, at every tier, with the first year of maintenance included and renewal at roughly fifteen percent per year. Subscription is available on Unlimited and Distributed only.

Autodesk Netfabb: Is there a perpetual licence?

No. Autodesk sells subscription only across its product range.

Flow Software: Do I need a historian as well?

Effectively yes. Flow reads from historians, databases and OPC sources; it is a calculation layer, not a data collector.

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.

Flow Software: What counts as a measure?

Each configured KPI or event definition. A single line typically consumes ten to thirty, which is what makes the 250 Starter cap tighter than it looks.
