Eiger vs SuperSlicer

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.

SuperSlicer is a free 3D-printing slicer for Linux, macOS, and Windows. It converts STL, OBJ, AMF, or 3MF models into G-code for FFF printers or PNG layers for mSLA printers. The project describes compatibility with modern RepRap-toolchain printers and firmware based on Marlin, Prusa, Klipper, and others. It is a personal fork of PrusaSlicer, which itself comes from Slic3r, and uses the GNU Affero General Public License version 3. Print preparation controls cover top-surface quality, infill density, thin walls, hole dimensions, overhangs, brims, and seams. Multiple extruders, separately configured objects, variable layer heights, and varied infill patterns are supported. Generated calibration tests and built-in calibration prints help with tuning. A command-line interface works without the graphical interface, while macros and post-processing scripts extend G-code handling. Prebuilt 64-bit releases and nightly builds are listed; the maintainer says Linux and macOS builds were compiled but not tested.
