Eiger vs KISSlicer

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.

KISSlicer turns STL files into printer-ready G-code and is a slicer, not a printer control app. Four Profile Wizards help configure printer, material, style, and support settings. Automatic support generation, resin slicing, and variable layer height are supported. The free plan costs nothing and allows multi-extruder printers to be used, but only one extruder can be selected for a print. Pro costs $42, paid once and enables multi-material printing, with extruders assignable to the raft, support, model, and sub-meshes. Premium costs $82, paid once and includes Pro functionality alongside listed features such as colorized meshes, texturing, dynamic density and gyroid infill, warp compensation, and curved surfaces. Profiles can be shared, and Project Files can archive print settings. The software supports Windows, macOS, and Linux; downloads are also listed for FreeBSD and Raspberry Pi. Its license permits commercial use and installation on multiple personal computers, with no time or model-size limit, and prohibits reverse engineering.
