Alibre Design vs PrusaSlicer
The short version
- Only PrusaSlicer has a free tier, so it costs nothing to try first.
- Each has a real cost: Alibre Design perpetual licences do not include updates; maintenance is a separate yearly plan starting at $50 per year for CAD support and updates; PrusaSlicer limited to slicing workflow only; no interactive 3D design capabilities
- They diverge on capability: Alibre Design covers Parametric modeling, PrusaSlicer covers Automatic supports.
