The software features intuitive tools (like smart fill and brushstroke tools) for painting color changes directly onto the model. Users can preview how the final print will look and adjust material adhesion settings to optimize print quality.

STEP File Support

You can import STEP files directly meaning there’s no need to convert CAD models into STL files. Since STEP files retain more geometric information, working with them also improves print accuracy. It supports all other popular file formats like STL, OBJ, 3MF, and AMF.

Prusa Slicer comes with built-in profiles for third-party printers, including models from Creality, Voron, and Anycubic. These profiles are developed with community input for optimized settings for various hardware. This feature makes it easier for users to get high-quality prints without extensive manual configuration.

The print preview includes a breakdown of estimated print time by features, such as infill, supports, and perimeters. Users can adjust settings and see real-time updates on print duration. Prusa Slicer also includes advanced cooling and temperature controls for overall better print quality and material adhesion.

Direct G-Code Transmission

Prusa Slicer supports multiple G-code formats which makes it compatible with RepRap, MakerBot, Mach3, and other firmware types. Users can send G-code directly to printers through OctoPrint, Repetier Host, or FlashAir SD cards. Additionally, G-code previews provide a layer-by-layer visualization of the print. We used this to catch errors before starting a job.

Variable Layer Height Smoothing

Prusa Slicer allows different layer heights within a single print to optimize print speed and surface quality. The software automatically smoothes transitions between varying layer thicknesses. This is especially useful for detailed models that require high precision in some areas and faster printing in others. 

MSLA and Multi-Material Support

The software includes dedicated slicing options for MSLA resin printers. It also supports multi-material printing for FFF printers using the Prusa MMU2S unit. MSLA mode provides optimal resin exposure settings, while multi-material printing features enable the blending of different filaments. These capabilities expand the range of applications for beginners and professionals alike.
