‘Custom mode’ gives over 400 settings for granular control.

Recommended profiles tested for thousands of hours ensure reliable results.

Intent profiles print specific applications at the click of a button.

Prepare prints with a few clicks, integrate with CAD software for an easier workflow, or dive into custom settings for in-depth control. Trusted by millions of users, Ultimaker Cura is the world’s most popular 3D printing software. 3D printing became a business since the RepRap community was born, but we want to keep 3D printing free, and Slic3r will always be an independent project, not driven by any business or single vendor. It’s being used by tens of thousands of people all over the world, and there are more than 1,000 forks of it. Slic3r is based on a community of people working collaboratively on GitHub, discussing new features and testing them. All of these features were first introduced in Slic3r and are now part of the commercial software out there. Slic3r, being a true non-profit community project, allowed the people to experiment with several original new features that have become common thereafter such as multiple extruders, brim, microlayering, bridge detection, command line slicing, variable layer heights, sequential printing (one object at time), honeycomb infill, mesh cutting, object splitting into parts, AMF support, avoid crossing perimeters, distinct extrusion widths, modifiers, and much more. Readability and maintainability of the code are among the design goals. The code and the algorithms are not based on any other previous work. The Slic3r project was born in 2011 within the RepRap community as an effort to provide the growing 3D printing technology with an open and flexible toolchain.

It cuts the model into horizontal slices (layers), generates toolpaths to fill them and calculates the amount of material to be extruded. Slic3r is the tool you need to convert a 3D model into printing instructions for your 3D printer.
