Orca Slicer
Orca Slicer is a free, open source 3D printing slicer for FFF and FDM 3D printers, designed to turn 3D models into precise G-code with advanced calibration tools, intelligent print controls, and a user-friendly workflow. It gives makers a complete environment for preparing, tuning, previewing, and optimizing prints, with support for Windows, macOS, and Linux. Orca Slicer includes a comprehensive calibration suite for temperature towers, flow rate tuning, pressure advance, retraction tests, tolerance testing, maximum flow rate testing, and vertical fine artifact calibration, helping users fine-tune printers and filaments for better print quality. The slicer also offers precise wall and seam control, including outer wall spacing adjustments and scarf seams to improve accuracy and surface finish. It includes features for sandwich mode, polyholes, multi-plate workflows, printer setup, slicing settings, and detailed model preparation, giving users more control over how parts are printed.

Slic3r
The Slic3r project has been under active and massive development. Make sure you get 1.3.0 now or try the development builds! Slic3r is free software, developed by Alessandro Ranellucci with the help of several contributors and a wonderful community. Turn your 3D models into G-code. Visual preview of toolpaths. Advanced configuration management. Custom G-code with conditional logic. Print spool queue (print on multiple machines simultaneously) or send to OctoPrint. FDM/FFF and SLA/DLP. Modifiers (distinct settings on custom regions). Most features are exposed from command line, thus providing a handy tool for batch operations and custom integrations. A C++ library for building custom applications on top of the Slic3r internal algorithms. Handle 3D models (open, repair, transform, convert). Generate G-code in many flavors. Generate infill patterns. Send G-code over serial port. Estimate G-code printing time.
