Eiger review
A connected slicing and fleet-management workspace for Markforged printing teams.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Eiger is Markforged’s 3D printing software for engineers, designers, and manufacturing teams using Markforged printers. It imports STL files, applies slicing and fiber-routing settings, estimates print time and material cost, manages part files, and coordinates connected printer fleets. The platform supports browser-based and desktop workflows across web, Windows, macOS, and API access, with composite and metal printing workflows included in its scope.
The published plans show a freemium model with a free plan. Cloud Eiger provides browser-based slicing, fiber reinforcement and routing, printer fleet management, and real-time print monitoring. Offline Eiger is a standalone local deployment for offline part preparation, with USB and LAN Connector workflows and quarterly updates described by Markforged. Markforged also announced standalone software SKUs for end of life no later than April 1, 2026, so buyers should distinguish the documented Offline Eiger deployment from the current Cloud Eiger direction.
Eiger fits teams that need more than file slicing, particularly those coordinating connected Markforged printers across shared projects. Its part-file collaboration, print-job management, monitoring, and estimates support a workflow from preparation through production oversight. REST API integration can connect the software with other systems, while SAML 2.0 and OIDC support single sign-on through Okta, Microsoft Entra, and Google Workspace. Two-factor authentication and ISO 27001 are listed among its security and compliance signals. Choose Eiger for Markforged-centered composite-printing operations that value fleet visibility and controlled access; teams seeking a printer-agnostic slicer or broader standalone software continuity should consider alternatives.
