Eiger is Markforged's 3D printing software. It was designed from the ground up to be secure, easy to use, and convenient to access. The On-Premise version of Eiger allows users to import STL files to be converted into MFP builds. This version does not connect or exchange any information with our servers. Eiger On-Premise requires Windows 7 or OS X Yosemite (version 10.10) or later, 2GB RAM, and 1GB storage; Google Chrome is not required. Eiger deals with four kinds of data: STL files are the standard file type used by all additive manufacturing systems. STL files are exported by CAD and 3D modeling programs as a simplified mesh of only surface geometry. STL files lack metadata relating to CAD or the originating program. Internal Slicer Data is the intermediate representation of the sliced STL that we use in the Internal View. MFP Files (Markforged Print) are the raw output of Eiger that our Markforged printers use to print your part. Generic Application Data refers to both the application code served from the server to the user to run the application, and schema data sent from the user to the server that is used to make sure user data is not corrupted between updates. This includes information that associates part builds with organizations and users, versioning information, etc. Application Data sent from the user to the server does not include any CAD data.
