The slicer, also called slicing software, is a computer software used in the majority of 3D printing processes for the conversion of a 3D object model to specific instructions for the printer. In particular, the conversion from a model in STL format to printer commands in g-code format in fused filament fabrication and other similar processes.
We present these 10 free programs, ideal for both professionals and fans of 3D printing.

Cura is the benchmark slicer software for all Ultimaker 3D printers, but it can also be used with most other 3D printers. It’s fully open source and can be extended via a plugin system. As one of the most popular and widely used 3D printing slicers on the market, there’s a good chance that the optimal profile settings for your 3D printer are already available on the software, making it easy to get started right away.
PrusaSlicer (formerly known as Slic3r Prusa Edition or Slic3r PE) is our own in-house developed slicer software based on the open-source project Slic3r. It's open-source and you can get it in our Drivers & Apps Package. PrusaSlicer is a feature-rich, frequently updated tool that contains everything you need to export the perfect print files for your Original Prusa 3D printer.
MatterControl is a CAD and 3D printing software for your desktop computer. Featuring printer host functionality that lets you directly control and monitor printing when connected via USB, you can also slice STLs for export to SD card for offline printing and even generate designs in the new CAD section of the software.
A cloud-based solution to 3D printer management, 3DPrinterOS is a comprehensive suite that encompasses print job queuing and delegation, printer control, and an app-based plug-in system that allows for STL analysis and repair, plus in-cloud slicing.
Don’t be fooled by the acronym of this program. It may be called “Keep It Simple Slicer,” but it is actually a pretty sophisticated 3D printing software tool. Some have hailed it as a worthy alternative to the other 3D slicer software tools, others complain about the confusing interface.
Slic3r is the tool you need to convert a 3D model into printing instructions for your 3D printer. It cuts the model into horizontal slices (layers), generates toolpaths to fill them and calculates the amount of material to be extruded.
Our aim is to make our latest research in modeling and slicing available as quickly as possible in a powerful yet accessible software. It integrates several ground breaking ideas that our team developed over the years, such as cubic/tetrahedral infills, bridge support structures, optimal adaptive layer thickness optimization, progressive infills, efficient offsetting, tight protective shields, maximal self-supporting cavities, and advanced path planning for dual-color printing.
Control and monitor every aspect of your 3D printer and your printing jobs right from within your browser.
Repetier-Host can handle up to 16 extruders with different filament types and colors simultaneously and visualize the result with individual filament colors, so you can see your result before printing.
Keep your 3D models stored neatly in the cloud so you can access them anywhere. Simply upload your own .stl files for cloud based slicing or upload pre-sliced .gcode files.
