Cura vs PrusaSlicer: Which Should You Use?

Harry S.

Two Excellent, Free Slicers

Cura and PrusaSlicer are the two dominant free slicers for FDM printing. Both are actively developed, packed with features, and capable of producing excellent print quality. The real question is not which one is objectively better, but which one suits your printer, workflow, and preferred way of working.

Each slicer has its strengths, design philosophy, and approach to settings management. Some users prefer Cura’s flexibility and extensive plugin ecosystem, while others prefer PrusaSlicer’s cleaner workflow and more structured feature set. Many experienced makers actually keep both installed and use them for different types of projects depending on what they are printing.

Understanding where each slicer performs best can help you choose the right tool for your workflow and get more consistent results from your printer.

Cura's Strengths

Cura has the largest user base and one of the broadest printer profile libraries available. For owners of Creality, Anycubic, and many other budget friendly printers, Cura often provides stronger default profiles straight out of the box with minimal setup required.

Its plugin marketplace is also one of its biggest advantages. The Settings Guide plugin in particular is incredibly useful for beginners, adding detailed hover over explanations for almost every setting in the slicer. Cura’s tree support system has also long been considered one of the best available, although recent versions of PrusaSlicer have narrowed the gap considerably.

The interface itself is designed in a more guided and approachable way. Settings are organised in a clear, discovery focused layout, and the Recommended versus Custom toggle makes Cura genuinely accessible for both beginners and advanced users at the same time.

For larger prints that require careful support placement, Cura’s support painting tools are often considered more intuitive than PrusaSlicer’s equivalent system, allowing users to manually choose exactly where supports should or should not appear.

For multi colour printing on Bambu Lab AMS systems, Bambu Studio remains the more purpose built option due to its tighter hardware integration. Cura also benefits from a powerful post processing plugin system, giving advanced users the ability to apply custom G code modifications and workflow automation directly within the slicer.

PrusaSlicer's Strengths

PrusaSlicer offers one of the most polished Variable Layer Height systems currently available. The tool automatically applies fine layers to curved or detailed surfaces while using thicker layers on straighter sections, helping reduce print times without sacrificing visible quality. The interface is intuitive, easy to adjust manually, and consistently produces excellent results.

Unlike Cura, PrusaSlicer also supports both FDM and SLA or MSLA resin printing, making it a convenient all in one option for makers who use multiple printer types. Sequential printing is also handled particularly well, allowing objects to be printed one at a time on the same build plate so completed parts can potentially be removed before the full job finishes.

Its modifier mesh system is another standout feature, giving users the ability to apply entirely different print settings to specific regions of a model. This is especially useful for technical parts, prototypes, or models that require different strengths, infill densities, or layer heights in different sections.

PrusaSlicer’s ironing controls, covered further in our ironing guide, are also generally considered more adjustable and precise than Cura’s implementation. Its community driven fork, OrcaSlicer, expands on these foundations even further, which is why it has become increasingly popular among advanced users. For more on that, see our OrcaSlicer guide.

The software also includes stronger model analysis tools for identifying issues such as non manifold geometry and problematic overhangs before printing begins. For technical printing and work involving engineering materials, the deeper level of print profile control available in PrusaSlicer can be extremely valuable.
