Eiger vs OrcaSlicer

Eiger is Markforged software for preparing 3D prints and managing printer activity. In its browser-based workflow, users import STL or STEP files, arrange parts into a build, set slicing and fiber routing, and generate an MFP file for a Markforged printer. Selective fiber reinforcement controls support routing reinforcement within a part. Eiger also provides printer and print-activity management in one place. The free cloud platform is for Markforged devices; the maker describes it as suitable for institutions with one to one hundred printers. Cloud use requires an internet connection to upload, create, view, and share part, build, and print-job data. Offline Eiger runs without internet access and does not send user or part data to the cloud. Offline print files must be transferred by USB, or over a local network with LAN Connector installed. The Essential plan includes Job Requests for submitting, tracking, and fulfilling print requests. Blacksmith is an Eiger subscription feature for scanning printed parts and comparing them with design files. The maker says cloud build files are encrypted in transit and at rest, and that Eiger earned ISO 27001 certification.

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.
