The short version

  • Only OpenSCAD has a free tier, so it costs nothing to try first.
  • Each has a real cost: CoreTechnologie no pricing is published and the vendor sells through direct and regional channels, so there is no list price to anchor a negotiation and quotes differ by territory.; OpenSCAD script-based workflow, not interactive design interface
  • They diverge on capability: CoreTechnologie covers Native CAD conversion, OpenSCAD covers Script-based modeling.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

CoreTechnologie

  • No pricing is published and the vendor sells through direct and regional channels, so there is no list price to anchor a negotiation and quotes differ by territory.
  • Licensing is granular by format read and write pair, so the price you were quoted covers the translations you named and adding a customer with a different CAD platform later means going back for another line item.
  • It is a small independent vendor, so a buyer standardising a critical migration pipeline on it should weigh the concentration risk and check the support arrangement in their own region rather than assume global coverage.
  • Feature recognition on converted geometry works well on prismatic machined parts and much less well on complex freeform surfaces, so the rebuilt-as-editable claim needs testing on your own worst parts, not on a demo model.
  • 4D_Additive competes with entrenched incumbents such as Magics in industrial AM, so machine-side Build Processor support and bureau familiarity are thinner, which matters if you need your service provider to accept the output.

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)

Questions people ask

Is CoreTechnologie or OpenSCAD better?
Neither clearly leads. CoreTechnologie starts at On request and OpenSCAD at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, CoreTechnologie or OpenSCAD?
OpenSCAD has a free tier; the other does not. Paid plans start at On request for CoreTechnologie and Free for OpenSCAD.
Does CoreTechnologie or OpenSCAD run on more platforms?
CoreTechnologie runs on Windows, Linux. OpenSCAD runs on Windows, macOS, Linux, WebAssembly.
Can I use OpenSCAD for free?
Yes. OpenSCAD has a free tier, so you can try it without paying. CoreTechnologie starts at On request.
What is CoreTechnologie best used for?
CoreTechnologie is most often used for a tier supplier that receives catia from one customer and nx from another and must work in solidworks, a company migrating a cad library off one platform and needing feature-recognised, editable models rather than dumb solids, preparing additive builds from exact b-rep geometry where stl faceting would lose the tolerance you need, giving purchasing and manufacturing staff a viewer with real analysis without buying them cad seats. Of those, a tier supplier that receives catia from one customer and nx from another and must work in solidworks and a company migrating a cad library off one platform and needing feature-recognised, editable models rather than dumb solids are not what OpenSCAD is typically brought in for.
What can CoreTechnologie do that OpenSCAD cannot?
CoreTechnologie covers Native CAD conversion, Automatic geometry healing, Feature recognition, Simplification and defeaturing. OpenSCAD covers Script-based modeling, CSG operations, 2D to 3D extrusion, Parameterization.

Answered from the vendors’ own pages

CoreTechnologie: Is CoreTechnologie owned by a CAD vendor?

No. It is an independent German company, which is the main reason it appears in supply chains that must move data between competing CAD platforms.

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.

CoreTechnologie: Does conversion produce editable models?

3D_Evolution has feature recognition that rebuilds parametric features from solids. It is reliable on prismatic machined geometry and weaker on complex freeform surfaces, so test it on your hardest parts.

CoreTechnologie: What makes 4D_Additive different from a normal slicer?

It prepares builds on exact B-rep geometry rather than converting to STL first, so tolerance and surface accuracy are not lost to faceting before printing.

CoreTechnologie: Can it run unattended for large migrations?

Yes. Batch and server conversion is designed for high-volume migration and PLM pipeline use rather than desk-by-desk conversion.
