The short version

  • Only Markforged Eiger has a free tier, so it costs nothing to try first.
  • 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.; Siemens WinCC Unified licensing counts PowerTags, and archived tags are licensed separately from displayed tags, so a project that adds historian logging late can breach a tier and trigger an unbudgeted step-up purchase.
  • They diverge on capability: Markforged Eiger covers Continuous fibre routing, Siemens WinCC Unified covers TIA Portal engineering.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Markforged Eiger

  • A defence contractor needing air-gapped print preparation because part geometry cannot leave the site, which requires Eiger Offlinenot Siemens WinCC Unified
  • A manufacturing engineering group running several Markforged machines across sites from one queue and part librarynot Siemens WinCC Unified

Siemens WinCC Unified

  • A machine builder standardising on S7-1500 who wants HMI screens engineered in the same project as the PLC codenot Markforged Eiger
  • Replacing a WinCC V7 plant SCADA before the 2027 support cut-off without changing controller vendornot Markforged Eiger
  • A line supervisory system where operators and supervisors need browser access from tablets with no client software rolloutnot Markforged Eiger
  • A plant already committed to the TIA Portal toolchain, where the cost of a rival SCADA is the second engineering environment and the second set of skills rather than the licencenot Markforged Eiger

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.

Siemens WinCC Unified

  • Licensing counts PowerTags, and archived tags are licensed separately from displayed tags, so a project that adds historian logging late can breach a tier and trigger an unbudgeted step-up purchase.
  • There is no migration tool that converts a WinCC V7 project to Unified, so leaving the classic line before its 2027 support end means rebuilding screens, scripts and alarm configuration by hand.
  • Scripting moved from VBScript to JavaScript, which invalidates the script libraries in-house engineers accumulated over a decade on classic WinCC.
  • It is effectively bound to the Siemens controller stack; connecting Rockwell or Mitsubishi PLCs works through OPC UA but loses the shared tag database that is the main reason to buy it.
  • Three unrelated products share the WinCC name, and buyers who specify WinCC without saying Unified, V7 or OA regularly receive quotes for the wrong platform with different licensing and a different contractor pool.

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.

Siemens WinCC Unified: Should I buy WinCC Unified or WinCC V7?

Unified, for any new project. V7 and V8 receive no new features and support ends in 2027.

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

No. It only prepares and drives Markforged machines.

Siemens WinCC Unified: Is WinCC OA the same product?

No. WinCC OA came from ETM, has its own engineering environment and licensing, and is aimed at very large distributed systems. It shares only the brand.

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

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

Siemens WinCC Unified: What is a PowerTag?

An externally connected process variable in the runtime. Internal tags do not count, but archived tags are licensed separately from displayed ones.

Markforged Eiger: Where is the actual cost then?

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

Siemens WinCC Unified: Can operators use it from a browser without installing anything?

Yes, the runtime is HTML5, but concurrent browser clients need WebUX or Unified client licences.
