The short version

  • Only PrusaSlicer has a free tier, so it costs nothing to try first.
  • Each has a real cost: PrusaSlicer limited to slicing workflow only; no interactive 3D design capabilities; Inventor autodesk publishes no licence price through UK G-Cloud: every listing found there is reseller delivered training at 750 to 1,500 pounds per day rather than software licensing, and neither AWS Marketplace nor GSA carries the product
  • They diverge on capability: PrusaSlicer covers Automatic supports, Inventor covers Parametric modeling.
