3D Sprint vs OrcaSlicer

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.

OrcaSlicer is a free, open-source slicer for FDM 3D printers on Windows, macOS, and Linux. It controls speed, layer height, pressure, and temperature independently for walls, infill, supports, and other features. Calibration tools cover flow rate, pressure advance, temperature towers, retraction, tolerance, and maximum volumetric speed. Tuned presets are provided for hundreds of printers, including Bambu Lab, Prusa, Creality, and Voron. Jobs can be sent to and monitored on Klipper, PrusaLink, or OctoPrint printers. The slicer supports automatic supports, model repair, multi-material printing, and variable layer height, but not resin or cloud slicing. Input formats include STL, 3MF, STEP, DRC, OBJ, AMF, SVG, and ZIP; outputs include G-code, Gcode.3MF, OBJ, STL, DRC, and generic 3MF. The desktop app works offline without accounts or telemetry, keeping project data on the device. It is licensed under AGPL-3.0.
