OctoPrint vs OrcaSlicer

OctoPrint is free, open-source software that provides a web interface for controlling consumer 3D printers. From a browser, users can check print progress and temperatures, move the print head, and start, stop, or pause a job. The interface can show an embedded webcam feed and a visualization of the G-code being printed. A plugin system connects to OctoPrint’s official plugin repository for installation. Other listed features include timelapse recording, STL slicing, access controls, system commands, and event hooks. The site says it works out of the box with most consumer printers. Hosting options include Raspberry Pi, Android phone, Docker, Linux, Windows, and manual Mac installation. For OctoPi, Raspberry Pi 3B, 3B+, 4B, or Zero 2 is recommended; other hardware setups are not officially supported. Anonymous access is denied by default, and the documentation recommends a VPN or additional protection for internet access. OctoPrint does not control the embedded webcam, so its access controls cannot limit access to the webcam URL.

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.
