The short version

  • Only Formlabs PreForm has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; PTC Windchill no pricing is published at any tier, and per-user rates are heavily negotiable on multi-year commitments, so the first quote a buyer receives is rarely the achievable price and small buyers without volume have little leverage.
  • They diverge on capability: Formlabs PreForm covers Automatic orientation, PTC Windchill covers Part and BOM management.
  • 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.

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.

PTC Windchill

  • No pricing is published at any tier, and per-user rates are heavily negotiable on multi-year commitments, so the first quote a buyer receives is rarely the achievable price and small buyers without volume have little leverage.
  • Implementation dominates cost: data migration, configuration and training routinely account for the majority of three-year total cost of ownership, and large programmes run into seven figures of services.
  • Annual support and maintenance is charged as a percentage of licence value in the low-to-mid teens, so the bill continues indefinitely even in years when nothing is upgraded.
  • Upgrades between major releases are projects rather than updates, particularly where the deployment has been customised, and heavily customised sites often sit several versions behind.
  • The role-based licence tiers mean occasional participants such as purchasing or quality still consume paid seats unless you deploy Windchill Navigate, which is a further product to buy and configure.

Answered from the vendors’ own pages

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.

PTC Windchill: Is a perpetual licence still available?

PTC has moved decisively to subscription and now positions Windchill as a subscription product. Existing perpetual estates are supported but new perpetual sales are not the default route and should not be assumed.

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.

PTC Windchill: How much does Windchill cost?

PTC publishes nothing. Expect role-tiered per-user subscription plus modules, plus support at a percentage of licence value, plus implementation services that usually exceed the software.

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.

PTC Windchill: Does it require Creo?

No. Creo integration is deepest, but connectors exist for SolidWorks, NX, CATIA and Inventor. Mixed-CAD sites are common.

Formlabs PreForm: Does it run on Linux?

No. Builds are provided for Windows and macOS only.

PTC Windchill: Is it overkill for a hundred-person hardware company?

Usually yes, unless you are in a regulated sector. Below that scale a cloud-native PLM will reach useful state in weeks rather than quarters.
