The short version

  • Only GrabCAD Print has a free tier, so it costs nothing to try first.
  • Each has a real cost: GrabCAD Print it only drives Stratasys printers, so the free Standard tier is a hardware retention mechanism rather than a portable tool, and prepared jobs do not move to another vendor.; 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: GrabCAD Print covers Native CAD import, Siemens WinCC Unified covers TIA Portal engineering.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

GrabCAD Print

  • It only drives Stratasys printers, so the free Standard tier is a hardware retention mechanism rather than a portable tool, and prepared jobs do not move to another vendor.
  • Pro is 5,000 US dollars per named user per year on top of machines that already cost six figures, and there is no floating licence in the standard offer, so shift-based teams buy multiple seats.
  • The production features that most justify the spend, nesting and manufacturing templates, are all locked behind Pro, meaning the free tier is not viable for a bureau.
  • Stratasys materials are proprietary and cartridge-locked, so the software sits on top of a consumables model where the recurring cost is set entirely by the vendor.
  • Support and feature coverage vary by printer family; newer technologies such as SAF and the Neo SLA line have historically lagged FDM in the depth of preparation options exposed.

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

GrabCAD Print: Is GrabCAD Print free?

GrabCAD Print Standard is free for Stratasys printer owners. GrabCAD Print Pro is 5,000 US dollars per user per year.

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.

GrabCAD Print: Can it drive a non-Stratasys printer?

No. It is tied to Stratasys hardware.

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.

GrabCAD Print: What do I actually get for the Pro fee?

Nesting, manufacturing templates, part labelling, wall thickness analysis and build cost estimation. These are production rather than prototyping features.

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.

GrabCAD Print: Is there a trial?

Yes, Stratasys has offered 30 and 60 day trials of Pro.

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.
