GrabCAD Print vs OrcaSlicer

GrabCAD Print prepares and manages 3D printing workflows with Stratasys printers. Standard tools include CAD import, print queue organization, support generation, printability validation, and part checking and repair. The product lists FDM, SAF, PolyJet, P3 and SLA workflows, alongside third-party integration options. Pro adds Manufacturing Templates, 3D Arrays, Accuracy Center, Thickness and Gap Analysis, and per-part estimation. It supports native CAD compatibility and lists a broad range of input files; STL, 3MF and OBJ are among the listed import or export formats, while stated output formats are STL and 3MF. The Android and iPhone app lets users monitor print progress, receive notifications and make adjustments. GrabCAD Print can run in Offline Mode, though some features are unavailable there. Pro requires a license assigned through a GrabCAD Control company account, and users must be logged in to connect to that account. Standard costs nothing; Pro costs $5,000 a year per user. Desktop requirements list 64-bit Windows 11 or newer, or Windows Server 2016 or newer.

OrcaSlicer is a free, open-source slicer for FDM 3D printers on Windows, macOS, and Linux. It controls speed, layer height, pressure, and temperature independently for walls, infill, supports, and other features. Calibration tools cover flow rate, pressure advance, temperature towers, retraction, tolerance, and maximum volumetric speed. Tuned presets are provided for hundreds of printers, including Bambu Lab, Prusa, Creality, and Voron. Jobs can be sent to and monitored on Klipper, PrusaLink, or OctoPrint printers. The slicer supports automatic supports, model repair, multi-material printing, and variable layer height, but not resin or cloud slicing. Input formats include STL, 3MF, STEP, DRC, OBJ, AMF, SVG, and ZIP; outputs include G-code, Gcode.3MF, OBJ, STL, DRC, and generic 3MF. The desktop app works offline without accounts or telemetry, keeping project data on the device. It is licensed under AGPL-3.0.
