STL Web-Viewer Demo:

STL Viewer:


After a short delay, as an example, a single “weaire phelan structure” should be shown in the viewer.
If the window is left empty, most likely the browser version is already outdated.

How to view your own STL file here:

For viewing purpose, you can simply drag&drop any local STL file onto the STL viewer window!

  • Once the file is uploaded, it will be visualized in the window.
  • depending on the file size, this might take a while,
  • I also discovered a file size limit of about less than 50MB

What happens with the uploaded data?

The STL data is loaded from the local disc into the browser’s (heap) memory and is not going to be stored somewhere else.
