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.

ideaMaker
IdeaMaker prepares Gcode for 3D printing and support STL, OBJ, OLTP and 3MF files. It features user-friendly interface and limitless customization for advanced users.
For example, ideaMaker allows adaptive layer heights to automatically adjust the layer height depending on detail level required for printed area, further improving quality and reducing print time. Furthermore, user can differentiate the settings for single or multiple models by Modifier, Per-Group Setting, and Per-Layer Setting. In additional, ideaMaker provides customized support, free cut and model repair.
ideaMaker is seamlessly linked to Raise3D’s other resources and tools. RaiseCloud is a cloud-based printer management platform enabling automate small batch manufacturing and print remotely. ideaMaker Library is an open library for user to get and share slicing profiles, model files and printing files. ideaMaker enables user to upload Gcode to Octoprint, thus its connected any 3rd party open-source 3D printer.

3dSynth
3dSynth is a generative 3D printing tool that creates G-code directly from mathematical rules instead of traditional 3D models. It completely bypasses the STL and slicer workflow, allowing users to generate printer-ready toolpaths straight from adjustable parameters. Every form is defined numerically, giving precise control over shape, texture, and structure in real time. Users can stack modular effects like ripples, blobs, noise, twists, and polygons to build complex organic or geometric surfaces. A real-time 3D preview shows the exact toolpath as it will be printed, helping catch issues before exporting. Spiral vase mode enables continuous Z printing for single-wall objects like vases and lampshades with translucent and sculptural effects. The final output is optimized G-code compatible with common FDM/FFF printers, ready to print without post-processing.
