The short version

  • Only PrusaSlicer has a free tier, so it costs nothing to try first.
  • Each has a real cost: Ignition requires real engineering to implement; it is a platform rather than a finished application; PrusaSlicer limited to slicing workflow only; no interactive 3D design capabilities
  • They diverge on capability: Ignition covers Unlimited-client licensing, PrusaSlicer covers Automatic supports.

Where each one falls short

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

Ignition

  • Requires real engineering to implement; it is a platform rather than a finished application
  • Steep learning curve, and Inductive Automation runs its own training programme because of it
  • Self-hosted and self-supported by default, so plant IT carries the availability burden
  • Module-based pricing means the entry figure is rarely the final one

PrusaSlicer

  • Limited to slicing workflow only; no interactive 3D design capabilities
  • Designed for RepRap-based printers; compatibility with other printer architectures varies

Answered from the vendors’ own pages

Ignition: What does Ignition cost?

It publishes per-server module pricing with unlimited clients, tags and connections, so cost does not scale with how many people use it.

PrusaSlicer: How much does PrusaSlicer cost?

PrusaSlicer is completely free and open-source software developed by Prusa Research.

Source
Ignition: Why does unlimited-client licensing matter?

Traditional SCADA is licensed per tag or per screen, which turns adding an operator terminal into a purchase. Ignition removes that ceiling.

Ignition: Is it a finished application?

No, it is a platform. Screens, tags and logic are built for the specific plant, which is real engineering work.
