GrabCAD Print vs KISSlicer

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.

KISSlicer turns STL files into printer-ready G-code and is a slicer, not a printer control app. Four Profile Wizards help configure printer, material, style, and support settings. Automatic support generation, resin slicing, and variable layer height are supported. The free plan costs nothing and allows multi-extruder printers to be used, but only one extruder can be selected for a print. Pro costs $42, paid once and enables multi-material printing, with extruders assignable to the raft, support, model, and sub-meshes. Premium costs $82, paid once and includes Pro functionality alongside listed features such as colorized meshes, texturing, dynamic density and gyroid infill, warp compensation, and curved surfaces. Profiles can be shared, and Project Files can archive print settings. The software supports Windows, macOS, and Linux; downloads are also listed for FreeBSD and Raspberry Pi. Its license permits commercial use and installation on multiple personal computers, with no time or model-size limit, and prohibits reverse engineering.
