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.; Simplify3D every serious competitor is free, so the $199 has to be justified against Cura, PrusaSlicer, OrcaSlicer and Bambu Studio on support and consistency alone, not on capability.
  • They diverge on capability: Formlabs PreForm covers Automatic orientation, Simplify3D covers Process-based slicing.
  • 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.

Simplify3D

  • Every serious competitor is free, so the $199 has to be justified against Cura, PrusaSlicer, OrcaSlicer and Bambu Studio on support and consistency alone, not on capability.
  • Major version upgrades are chargeable, so the perpetual licence covers a version rather than the product and the cost recurs every few years anyway.
  • Development cadence is slower than the open source slicers, and features such as newer tree support algorithms and multi-material handling appear there first.
  • Printer profiles for very new machines lag behind the manufacturer's own bundled slicer, so buyers of a brand new printer may get better results from the free tool that shipped with it.
  • Standard licences require an internet connection to activate, and the offline option is a separate purchase negotiated with sales rather than a checkbox at checkout.

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.

Simplify3D: Is Simplify3D a subscription?

No. It is a one-time purchase of $199 per user, but upgrades to future major versions cost extra.

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.

Simplify3D: Why pay when PrusaSlicer and Cura are free?

For a mixed fleet you get one interface and one profile library across brands, plus a supplier to call. If you run one printer from one vendor, the free slicer is usually the better choice.

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.

Simplify3D: Can I install it on more than one computer?

A standard licence is per user with online activation. Teams needing shared or concurrent use buy floating licences, priced on request.

Formlabs PreForm: Does it run on Linux?

No. Builds are provided for Windows and macOS only.

Simplify3D: Can I try it first?

There is a two week money-back guarantee rather than a free trial download.
