Convert PAR to STL

Verified by Adam B.· reviewed by FE Editorial ·updated Aug 26, 2026
QUICK ANSWER
Is it possible to convert PAR to STL?
Yes - PAR converts to STL.

Open the .par in Solid Edge, use File > Save As and select STL, then adjust tessellation settings before saving. If you do not have Solid Edge, CAD Exchanger can open .par files and export to STL on Windows and macOS.

Also to STL: P21 · MEB · STEP

Why convert PAR to STL?

STL is the standard format for 3D printing. Slicers such as Cura, PrusaSlicer, and Bambu Studio read STL, not CAD part files. Converting a Solid Edge part to STL is how engineers hand off geometry to a print service, prototype shop, or their own printer.

How to convert PAR to STL

Solid Edge EASIEST

Open the .par in Solid Edge, use File > Save As and select STL, then click Options to set units and lower surface deviation for smoother curves before saving.

CAD Exchanger APP

Open the .par in CAD Exchanger (freemium, Windows and macOS), set mesh parameters as needed, and export to STL without a Solid Edge license.

About these formats

.PAR Solid Edge Part

A PAR file is a 3D CAD part file from Siemens Solid Edge - it holds a single mechanical part's geometry, feature tree, and metadata. To view it for free, use the official Solid Edge Viewer.…

.STL Stereolithography / Standard Tessellation Language file

An STL file is a 3D model that describes a shape as a mesh of triangles. To view it, use Microsoft 3D Viewer (Windows) or Quick Look (macOS). To 3D-print it, open it in a slicer like…

Quality & what to watch

  • STL stores a triangulated surface mesh only - no feature tree, sketch history, parameters, or material properties. Keep the original .par for any future edits.
  • Mesh quality depends on tessellation settings: lower the surface deviation in Solid Edge's export options to reduce visible faceting on cylinders and fillets.
  • Units are not embedded in STL - set mm or inches in the export options to match what your slicer expects.

Frequently asked questions

Can I convert PAR to STL without Solid Edge?
Yes - CAD Exchanger reads Solid Edge .par files and exports to STL on Windows and macOS; the free tier has file size and conversion limits.
Will the STL look faceted?
It can at coarse tessellation settings. Lower the surface deviation in the export options to get smoother curves at the cost of a larger file.
Can I edit the STL in my slicer?
Slicers can orient, scale, and slice the STL for printing, but parametric features from Solid Edge are gone - edit the original .par for any design changes.
