How Eiger Works


Eiger is MarkForged's 3D printing software. It was designed from the ground up to be secure, easy to use, and convenient to access.

There are four kinds of data that Eiger deals with:

  1. STL files
  2. Internal Slicer Data
  3. MFP Files
  4. Generic Application 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 (see, e.g., this STL format description).

Internal Slicer Data is the intermediary representation of the sliced STL that we use on the Internal View.

MFP Files (MarkForged Print) is the raw output of Eiger that the Mark One uses 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. 

Configuration Information

Eiger Cloud

 
 

Eiger backs up your data in our secure cloud storage system. Only members of your Organization on Eiger have access to your data. MarkForged employees cannot access any of your data without explicit permission from you.

All communication with MarkForged services is encrypted.

Eiger Desktop

 
 

The Desktop version of Eiger allows users to save their STL files, Internal Slice Data and MFP Files on their hard drive. The only information that is exchanged with the Eiger Server is Application Data.
