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.; COMSOL Multiphysics the base licence covers very little on its own and nearly every practical problem needs one or more add-on modules, each priced separately, so the quoted total is typically a multiple of the headline base figure.
  • They diverge on capability: Autodesk Netfabb covers Mesh repair, COMSOL Multiphysics covers Coupled multiphysics solving.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

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

Autodesk Netfabb

  • A metal additive bureau predicting distortion on a laser powder bed build before committing twenty hours of machine timenot COMSOL Multiphysics
  • An aerospace supplier applying automatic geometry compensation so printed parts land within tolerance without iterative trial buildsnot COMSOL Multiphysics
  • A production department nesting hundreds of small parts into a single polymer build to raise volume utilisationnot COMSOL Multiphysics
  • An engineering team that already subscribes to Fusion and wants AM preparation without adding a second vendornot COMSOL Multiphysics

COMSOL Multiphysics

  • Modelling a device where physics are strongly coupled, such as induction heating that changes material properties which change the fieldnot Autodesk Netfabb
  • Research work needing custom partial differential equations that no packaged solver in a mainstream tool providesnot Autodesk Netfabb
  • Packaging a validated model as an app so process engineers can run studies without learning the simulation toolnot Autodesk Netfabb
  • A department wanting shared concurrent access via a Floating Network Licence, with cluster runs at no extra licence costnot Autodesk Netfabb

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.

COMSOL Multiphysics

  • The base licence covers very little on its own and nearly every practical problem needs one or more add-on modules, each priced separately, so the quoted total is typically a multiple of the headline base figure.
  • Perpetual licences renew maintenance at 20% of the then-current price each year, and because that percentage applies to the whole module stack the annual bill grows as your module list does and as list prices rise.
  • No pricing at all is published, so procurement cannot benchmark or budget without a sales engagement, and comparisons against Ansys or SolidWorks Simulation are effectively impossible before that point.
  • Named Single-User and CPU-locked licences do not share, so a team of six that bought individual licences ends up with idle seats while a Floating Network Licence would have covered them, and switching licence type is a commercial renegotiation.
  • Solving strongly coupled systems is memory hungry and slow, and models that look modest in the GUI routinely need tens of gigabytes of RAM, so hardware cost is a real and often underestimated part of adoption.

Questions people ask

Is Autodesk Netfabb or COMSOL Multiphysics better?
Neither clearly leads. Autodesk Netfabb starts at $4415/year and COMSOL Multiphysics at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Autodesk Netfabb or COMSOL Multiphysics?
Autodesk Netfabb starts at $4415/year and COMSOL Multiphysics at On request.
Does Autodesk Netfabb or COMSOL Multiphysics run on more platforms?
Autodesk Netfabb runs on Windows, Desktop. COMSOL Multiphysics runs on Windows, Linux, macOS.
What is Autodesk Netfabb best used for?
Autodesk Netfabb is most often used for a metal additive bureau predicting distortion on a laser powder bed build before committing twenty hours of machine time, an aerospace supplier applying automatic geometry compensation so printed parts land within tolerance without iterative trial builds, a production department nesting hundreds of small parts into a single polymer build to raise volume utilisation, an engineering team that already subscribes to fusion and wants am preparation without adding a second vendor. Of those, a metal additive bureau predicting distortion on a laser powder bed build before committing twenty hours of machine time and an aerospace supplier applying automatic geometry compensation so printed parts land within tolerance without iterative trial builds are not what COMSOL Multiphysics is typically brought in for.

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.

COMSOL Multiphysics: Does the base licence include CFD or structural mechanics?

Only limited capability. Serious CFD, structural, RF and acoustics work each require the relevant add-on module at extra cost.

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.

COMSOL Multiphysics: What does maintenance cost?

Perpetual licences include 12 months of updates and support, then renew at 20% of the then-current price per year.

Autodesk Netfabb: Is there a perpetual licence?

No. Autodesk sells subscription only across its product range.

COMSOL Multiphysics: Which licence type should a team buy?

Floating Network if more than a couple of people use it, since it shares concurrency and includes cluster and cloud computing at no extra charge.

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.

COMSOL Multiphysics: Is pricing published?

No. COMSOL publishes licence types but no prices; every purchase goes through a quote.
