Cura vs PrusaSlicer: Which Should You Use?

Two Excellent, Free Slicers

Cura and PrusaSlicer are the two dominant free slicers for FDM printing. Both are actively developed, feature-rich, and capable of producing excellent results. The question isn't "which is better?" but rather "which is better for your specific situation?" They have genuinely different strengths, and the right choice depends on your printer, your workflow, and which interface resonates with the way you think about settings. Many experienced makers use both — each for different tasks — and this guide will help you understand when each excels.

Cura's Strengths

Cura has the largest user base and the broadest printer profile library. For Creality, Anycubic, and many other budget printer owners, Cura often provides better default profiles out of the box. Its plugin marketplace is extensive — the Settings Guide plugin alone (adding hover-over explanations for every setting) is extraordinarily valuable for beginners. Cura's implementation of tree supports has historically been strong, though recent versions of PrusaSlicer have caught up significantly.

Cura's interface is more linear and guided — settings are presented in a more discovery-friendly way, with the Recommended/Custom toggle making it genuinely usable at multiple skill levels simultaneously. For large prints that need careful support management, Cura's support-painting tool (manually marking which surfaces should and shouldn't receive supports) is more intuitive than PrusaSlicer's equivalent. For multi-colour printing on Bambu Lab AMS systems, BambuStudio (Cura-adjacent) is purpose-built. The post-processing plugin system allows powerful G-code modifications for advanced users.

PrusaSlicer's Strengths

PrusaSlicer has the most polished Variable Layer Height implementation — the tool for automatically assigning fine layers to curved surfaces and thick layers to straight walls is intuitive and produces excellent results. Support for SLA/MSLA resin printing (in addition to FDM) makes it a single tool for makers with both printer types. Sequential printing (printing objects one at a time on the same bed, allowing earlier objects to be removed mid-job) is better implemented in PrusaSlicer than in Cura. The modifier mesh system (applying different settings to specific regions of a model) is powerful and well-executed.

PrusaSlicer's ironing implementation (see our ironing guide) is more controllable than Cura's. Its OrcaSlicer fork takes PrusaSlicer's foundation even further — see our OrcaSlicer guide for why it's becoming popular. The model analysis tools (checking for non-manifold geometry, visualising overhang angles) are more developed. For technical printing with engineering materials, the additional control over every aspect of the print profile is valuable.

The Practical Recommendation

Install both. Use the one that ships with your printer or that has profiles for it. Migrate to the other when you hit a limitation in your current slicer. Most makers end up with a preference that's largely aesthetic — one interface just "clicks" better than the other. The third option worth mentioning: OrcaSlicer, a PrusaSlicer fork with enhanced calibration tools, is gaining significant traction and may be worth evaluating alongside both. Whichever slicer you use, quality Australian filament responds predictably and makes learning your slicer's settings much easier.
