Lychee Slicer vs PrusaSlicer

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.

PrusaSlicer converts a 3D model into files for a 3D printer. It is free, open-source software based on the Slic3r project, and it performs slicing on the user's computer without requiring an account. The listed desktop downloads are for Windows, macOS, and Linux; the Windows download requires Windows 10 or later. Simple, Advanced, and Expert modes offer different levels of control. Users can create organic-shaped supports, paint support zones, and paint material regions. The software supports MMU3 and multi-extruder setups, plus layer-by-layer filament changes for basic multicolor prints. Its cut tool can divide a model and add alignment pins at the join. A built-in Printables.com browser supports finding and importing models for slicing. Printer connections include Prusa Connect, Klipper, and OctoPrint. A command-line interface supports batch slicing and custom manufacturing pipelines. Models, profiles, and G-code stay on the computer unless sent elsewhere. Prusa provides a support section in its Knowledge Base.
