GrabCAD Print vs Lychee Slicer

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.

Lychee Slicer prepares 3D models for resin and filament printing, with tools for supports, hollowing, print-setting previews and printer configuration. It runs on Windows, macOS and Linux, and Lychee says it supports more than 750 printers. Resin features include custom support structures, exposure settings, grid supports, AR preview and one-click hollowing. Filament tools include printer profiles, support management, seam optimization and real-time preview. Compatible filament printers can communicate through Klipper or OctoPrint; Wi-Fi sending depends on the printer model. Lychee Library is integrated into the slicer and offers pre-supported models from creators. The product describes cloud synchronization of settings across machines and automatic local backups. Lite is free, with limited Multi-Plate and ads on export. Plus is billed at €99.90 + local taxes yearly (€8.33 / month). Plus & Library is billed at €199.90 + local taxes yearly (€16.66 / month), and includes unlimited model downloads. Library models cannot be used commercially without creator approval.
