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.

3D Print Pass is a browser-based workspace for preparing and reviewing 3D-printing projects. Its workflows include STL and 3MF model checks; model inspection and preparation in Print Studio; written-symptom troubleshooting for failed prints; source and rights evidence checklists; and tools for sellers preparing listings. Users can organize findings and project context for handoffs to customers or independent print providers. The public beta includes a live Studio sample, browser-based listing-image layouts, sample reports, and practical guides. Pricing includes free features, credits, and monthly plans. Reports explain their evidence and limitations, and users should confirm findings in their chosen slicer and on the physical printer.
