3D Sprint vs PrusaSlicer

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.

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.
