While tools and features are essential, the user interface and experience can make or break software.

Both slicers have easy-to-use interfaces. However, Cura provides a cleaner and more modern interface, while PrusaSlicer looks a bit outdated.

Both softwares provide easy-to-use tools and simple navigation.


  • Design: Cura provides a more modern and cleaner user interface.
  • Organization: The layout is neatly organized. Despite many tools and settings, everything is organized under headings and dropdowns, making it easy to find what you need.
  • Print Estimations: Cura provides print time and filament estimations after you slice a 3D model. The estimates allow you to optimize your settings and orientation to minimize print time and filament.
  • Workflow: Cura divides the workflow into three stages; Prepare, Preview, and Monitor. The Prepare tab is where you set your print settings. After slicing a model, you can view the output in the Preview tab. Viewing the output before printing is helpful to check if you forgot something like infill or support. You can also view connected printers in the Monitor tab. This is especially useful for checking on long prints when you are away. 


  • Design: PrusaSlicer uses a simple but intuitive design. While a bit outdated, Prusa organizes the settings in a way that’s easy to view and navigate.
  • Settings Level: You can alter the settings level based on your expertise, from beginner to expert. Adjusting the settings level allows you to cut through the clutter and hide advanced tools to focus on the most essential settings.
  • Smart Manipulation: Let PrusaSlicer automatically arrange the models on the build plate to optimize for space, print time, and filament usage. This setting is beneficial when printing multiple objects at a time.

Printer Support

Cura supports a wide range of printers from various brands, offering more flexibility and adaptability. Like Cura, PrusaSlicer is compatible with a wide range of 3D printers. But PrusaSlicer is best used with Prusa 3D printers.

To choose the slicer best suited for your printer, check if your printer model is listed in the slicer’s supported devices.

Slicer Settings

Cura’s slicer settings are neatly organized in tabs. The photo above shoes the advanced settings with hundreds of options to fine-tune prints.

Both slicers offer extensive slicing settings to help achieve optimal print results. Slicer settings like layer height, wall thickness, print speed, infill, and more adjust how the printer creates your model.

Small adjustments can significantly impact print quality, time, and filament usage.

Both offer all the basic printing settings, and you can get exceptional quality prints using either software.

Cura has more default profiles and tools, giving you more options to fine-tune your prints. They offer more features and functionality than any other slicer software.

The software offers all the essential tools you’d expect, plus several advanced tools for pro makers.

The experimental tools allow users to test new features and provide feedback. If the tools are popular, Cura may add them as default settings.

A tool like tree supports used to be an experimental tool in Cura. But after community feedback, the support setting became a standard setting.

PrusaSlicer may have fewer tools, but they have everything you need to produce great prints.

The software gives you all the essential tools to fine-tune your printing.

The slicer is specifically tuned to work with Prusa printers. You’ll notice slightly better print quality when using PrusaSlicer with Prusa 3D printers. 

We also found that PrusaSlicer is faster than Cura when slicing files. PrusaSlizer also optimizes the nozzle path for faster print times – around 10-20% faster on average.

The print speed is one of the primary reasons people switch to Prusa

One of the most significant differences with PrusaSlicer is the support for resin SLA 3D printers. Working with filament and resin printing is a considerable bonus for users with two sets of printers.

PrusaSlicer eliminates the need to use separate software by providing tools for both styles of 3D printing.

Overall, Cura has more tools and advanced features than PrusaSlicer, but PrusaSlicer works best for Prusa printers and resin printers.

Support Settings

PrusaSlicer introduced its own version of organic support with PrusaSlicer 2.4. Like tree supports, organic supports use less filament and print faster compared to traditional support structures like grids.

In my experience with both support settings, I’ve found that Prusa’s organic supports are smaller, more natural, and result in smoother finishes after removal.

Preview and Slicing

Both slicers provide a preview and slicing feature. However, Cura has a more detailed layer-by-layer preview of the print, which can help identify potential issues before printing. PrusaSlicer also offers a preview function, but it may lack the level of detail Cura provides.


Both slicer software have large and active user communities, which can be a valuable resource for troubleshooting and learning from others. Cura has a slightly larger user base and has been around longer, but PrusaSlicer’s community is also growing rapidly.
