The short version

  • Each has a real cost: Markforged Eiger eiger only drives Markforged printers, so the free software is a lock-in mechanism; the moment you want a different machine none of your prepared parts or fibre routing transfers.; OpenSCAD script-based workflow, not interactive design interface
  • They diverge on capability: Markforged Eiger covers Continuous fibre routing, OpenSCAD covers Script-based modeling.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Markforged Eiger

  • Eiger only drives Markforged printers, so the free software is a lock-in mechanism; the moment you want a different machine none of your prepared parts or fibre routing transfers.
  • The standard product is cloud only, meaning part geometry is uploaded to a vendor service, which is unacceptable for many defence and aerospace sites and forces them onto the paid Eiger Offline subscription per machine.
  • Eiger Offline pricing is not published and is charged per machine, so a shop with several printers pays repeatedly for software the cloud users receive free.
  • Slicing control is deliberately simplified compared with open slicers, and experienced operators regularly find they cannot reach a parameter they want without contacting support.
  • Markforged has been through financial pressure and consolidation in the additive sector, and because the software is inseparable from the hardware, a change of ownership or product line pruning would strand the fleet rather than just the tool.

OpenSCAD

  • Script-based workflow, not interactive design interface
  • Limited to constructive solid geometry and 2D extrusion modelling
  • Not suitable for artistic 3D modelling or computer animation
  • Complex build dependencies (Qt, CGAL, Boost)

Answered from the vendors’ own pages

Markforged Eiger: How much does Eiger cost?

Nothing, if you own a Markforged printer. It is included with every machine with no per-user or per-printer software fee. Eiger Offline is a separate paid per-machine subscription.

OpenSCAD: What is the cost of OpenSCAD?

OpenSCAD is free software with no licensing fees, subscriptions, or costs of any kind. The software is available as open-source with no restrictions on commercial or non-commercial use.

Source
Markforged Eiger: Can I use Eiger with a non-Markforged printer?

No. It only prepares and drives Markforged machines.

Markforged Eiger: Is my part geometry uploaded to the cloud?

Yes, in the standard product. Sites that cannot allow that need Eiger Offline.

Markforged Eiger: Where is the actual cost then?

In the printers and the proprietary filament and continuous fibre spools, which are the recurring spend.
