Whale with 4,198 faces (triangles) vs 332 faces The more triangles that cover the surface – the smaller each triangle will be and the smoother the surface of the model will appear. STL is a file format for 3D models that represents the surface geometry of the object as triangular surfaces.
Common backronyms for STL include Standard Triangle Language or Standard Tessellation Language. STL = a file format for 3D models created by the Albert Consulting Group for 3D Systems in 1987. Below, we outline, step-by-step, how to use Microsoft 3D Builder to reduce the file size of your 3D model that is STL format. This makes the face (surface) less smooth – but can dramatically reduce the size of the STL file as well. With the FREE tool you can reduce the face count – or number of vertices of the 3D model. The easiest way to reduce an STL file is to use Microsoft 3D Builder (Free on Microsoft Store) and SIMPLIFY the model. We found a free solution that was surprisingly easy to manipulate the STL files so they were a smaller size and could be uploaded to TinkerCAD. We tried various online utilities – but they did not work for us.
We were constructing a totem pole for my daughter’s social studies project and were trying to manipulate some existing models we found on Thingiverse into a totem pole. TinkerCAD only permits files that are 25 MB or smaller to be uploaded. We recently had an issue loading some files into TinkerCAD because they were too big.
