The short version

  • Only Formlabs PreForm has a free tier, so it costs nothing to try first.
  • Each has a real cost: COPA-DATA zenon the I/O count that determines your licence band is a weighted calculation, not a variable tally, so projects sized from a tag list routinely land in a higher and more expensive band than budgeted.; 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: COPA-DATA zenon covers I/O-banded licensing, Formlabs PreForm covers Automatic orientation.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

COPA-DATA zenon

  • The I/O count that determines your licence band is a weighted calculation, not a variable tally, so projects sized from a tag list routinely land in a higher and more expensive band than budgeted.
  • The integrator and engineering talent pool is concentrated in German-speaking Europe; a North American or Asian site can find itself dependent on a single partner with no competitive quote available.
  • English-language documentation and community material lag the German equivalents, which slows engineers who are learning the product without formal COPA-DATA training.
  • The annual software maintenance contract is a percentage of licence value, so a large I/O estate carries a recurring cost that does not fall even when the plant is stable and nothing is changing.
  • Third-party ecosystem extensions are far fewer than for Ignition or FactoryTalk, so requirements outside the box tend to become custom engineering billed at partner day rates.

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

COPA-DATA zenon: How is a zenon licence sized?

By calculated I/O count. Numeric variables are weighted upward in that calculation and binary values counted singly, so ask your partner for the calculated figure, not the variable count, before signing.

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.

COPA-DATA zenon: Is zenon only for factories?

No. A significant part of its installed base is electrical substation automation, where IEC 61850 support is native rather than an add-on.

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.

COPA-DATA zenon: Is there a free version?

There is a demo mode for evaluation and a free educational licence, but production runtime always needs a paid, I/O-banded licence.

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.

COPA-DATA zenon: Can zenon replace a PLC?

zenon Logic is an IEC 61131-3 soft PLC and can control non-safety-critical processes, but most deployments keep a hardware PLC and use zenon for visualisation and supervision.

Formlabs PreForm: Does it run on Linux?

No. Builds are provided for Windows and macOS only.
