GrabCAD Print vs SuperSlicer

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.

SuperSlicer is a free 3D-printing slicer for Linux, macOS, and Windows. It converts STL, OBJ, AMF, or 3MF models into G-code for FFF printers or PNG layers for mSLA printers. The project describes compatibility with modern RepRap-toolchain printers and firmware based on Marlin, Prusa, Klipper, and others. It is a personal fork of PrusaSlicer, which itself comes from Slic3r, and uses the GNU Affero General Public License version 3. Print preparation controls cover top-surface quality, infill density, thin walls, hole dimensions, overhangs, brims, and seams. Multiple extruders, separately configured objects, variable layer heights, and varied infill patterns are supported. Generated calibration tests and built-in calibration prints help with tuning. A command-line interface works without the graphical interface, while macros and post-processing scripts extend G-code handling. Prebuilt 64-bit releases and nightly builds are listed; the maintainer says Linux and macOS builds were compiled but not tested.
