3D Sprint vs Lychee Slicer

3D Sprint prepares CAD and polygon data for additive manufacturing and manages print jobs on 3D Systems plastic 3D printers. It imports native CAD files from industry-leading CAD systems, analyzes part geometry, corrects some CAD and STL translation errors, and offers manual polygon editing and hole filling. Preparation tools include automatic support generation, build placement, 3D nesting, printability checks, slicing, and estimates for build time and material. The software supports color-jet, digital light processing, multi-jet, stereolithography, and selective laser sintering printers, as well as resin slicing and multi-material printing. Users can submit jobs, manage queues and priorities, and view directly connected, networked, or shared printers. The Windows product accepts formats including STL, OBJ, PLY, STEP, IGES, and 3DS. Basic is a complimentary license included with purchases of specific 3D Systems plastic printers. A 30-day trial is available; paid pricing is on request. Pro upgrades an existing Basic license, and add-ons require an existing 3D Sprint license.

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.
