• Mesh preparation. This function allows repairing problematic meshes, correcting normals, and rounding vertices. It automatically detects errors in STL and AMF files. Performs boolean operations to combine or subtract models.
• Layer configuration. Adjusts layer height according to model requirements. Allows setting different heights for different regions of the model. Modifies surface quality and print time.
• Support generation. Creates structures for overhanging areas. Offers soluble and non-soluble supports. Configures the density and pattern of supports according to the geometry.
• Variable infill. Controls infill density in different sections of the model. Adjusts the amount of internal material based on structural needs. Saves material and time while maintaining strength.
• Multi-material configuration. Manages printers with multiple extruders. Assigns different materials or colors to specific parts of the model. Synchronizes extruder movements.
• Vase mode. Specialized for printing enclosed objects with a single opening. Creates continuous walls without the need for internal supports. Optimized for manufacturing containers and similar shapes.
• Extrusion calibration. Adjusts material flow to compensate for under-extrusion or over-extrusion. Includes extrusion multiplier tests and pressure compensation.
• Layer analysis. Detailed visualization of each layer of the printing process. Shows travel moves, retractions, and material changes. Debugging tool to verify the nozzle path.
• Print modifiers. Applies different settings to specific regions of the model. Changes parameters such as speed, flow, or temperature in defined areas.
• Material profiles. Stores specific settings for different filaments. Contains parameters for temperature, cooling, and flow compensation. Allows creating custom material libraries.
• Infill pattern generation. Offers multiple internal pattern options such as rectilinear, honeycomb, or gyroid. Affects the mechanical properties of the final part. Controls infill density and orientation.
• Print time optimization. Calculates the most efficient paths for the nozzle. Reduces unnecessary movements and travel time. Adjusts accelerations and speeds based on printer capabilities.
• Initial layer settings. Specialized for adhesion to the print bed. Controls line width, flow, and nozzle distance. Includes brim options and surface patterns.
• Support for different printers. Compatibility with multiple brands and models of 3D printers. Configuration of print area, geometry, and specific hardware features.
• G-code export. Generates specific instructions for the target printer. Includes customizable commands for pre- and post-processing. Allows adding custom scripts.

PrusaSlicer was initially developed by Prusa Research as a fork of Slic3r. Development began in 2016 to meet the specific needs of Prusa printers. The application is written primarily in C++ with Python components for some functionalities. The development team is led by software engineers from Prusa Research with contributions from the open-source community.
