BCN3D Stratos vs OrcaSlicer

BCN3D Stratos is free slicing software for preparing 3D prints with BCN3D Omega, Sigma, and Epsilon printers. It imports STL, 3MF, OBJ, and AMF files, then lets users translate, scale, and rotate parts. Validated printing profiles are included, while expert users can adjust more than 500 parameters. For IDEX technology, the slicer supports multi-material models, support structures, mirror mode, and duplication mode for two print heads. Layer View displays print sections; X-ray View reveals internal parts and hidden geometries. Completed G-code can be sent to a networked printer or saved to removable media such as an SD card. Other listed options include gyroid infill, brim and raft adhesion settings, and bridges. BCN3D says Stratos is based on the open-source slicer Cura. It runs on 64-bit Windows 10 or higher, Mac OSX 10.11 or higher, and Linux, but is not available for older 32-bit systems. The product page links to a knowledge base, onboarding video, and feature tutorials. The listed plan is free.

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.
