Slic3r

Slic3r is an open-source 3D printing toolbox developed by Alessandro Ranellucci. It is designed to convert 3D models into G-code, the language that 3D printers understand. According to the vendor, Slic3r is a versatile tool suitable for companies of all sizes, from small startups to large enterprises. It is used by professionals in the 3D printing industry, including designers, engineers, and technicians, as well as manufacturing companies, design studios, research institutions, and hobbyists.

Key Features

Fast G-code generation: According to the vendor, Slic3r is optimized for speed, allowing users to slice detailed models in a shorter time compared to other software. It utilizes multithreading for parallel computation, further enhancing the G-code generation process.

Wide range of input/output formats: Slic3r supports reading STL, AMF, and OBJ files, making it compatible with various 3D modeling software. It can output G-code and SVG files, providing flexibility for different 3D printers and workflows.

User-friendly interface and command line support: Slic3r offers a graphical interface with accessible features. Additionally, it provides command line support for batch operations and custom integrations, catering to the needs of both beginners and advanced users.

Open source and open development: Slic3r is open source software released under the AGPLv3 license. The vendor states that the development of Slic3r is centered on GitHub, where the community actively participates in testing, providing feedback, and contributing to the project.

Support for multiple printers and filaments: According to the vendor, Slic3r is compatible with a wide range of 3D printers, including RepRap, Ultimaker, Makerbot, Lulzbot, and more. It also supports multiple filaments and build styles, allowing users to manage different configurations and presets for each category.

Advanced configuration management: Slic3r provides advanced configuration options, allowing users to fine-tune settings for optimal print quality and performance. Users can save configurations as presets for different printers, filaments, and build styles, avoiding the need for duplication.

Custom G-code with conditional logic: According to the vendor, Slic3r allows users to customize G-code with conditional logic, enabling more complex and dynamic print workflows. This feature provides greater control over the printing process, allowing for advanced operations and customizations.

Visual preview of toolpaths: Slic3r offers a visual preview of toolpaths, allowing users to visualize how the printer will move and extrude material. This feature helps users identify potential issues, optimize print settings, and ensure the desired outcome before printing.

Support material generation: According to the vendor, Slic3r automatically generates support material for overhangs, improving print quality and enabling the creation of more complex geometries. This feature saves time and effort by automatically generating the necessary support structures for successful prints.

Sequential printing and print spool queue: Slic3r supports sequential printing, enabling users to print one complete object at a time in a single print job. It also offers a print spool queue feature, allowing users to print on multiple machines simultaneously or send prints to OctoPrint.
