The software that can be used to create STL files are Wings 3D, Autodesk Meshmixer, MeshLab, and Blender. These are good STL editors that let you create new 3D models in STL file format.

A file with .stl extension is a 3D graphic file native to Stereolithography technology. Stereolithography is basically a type of 3D printing technology to create 3D models.

The same part imported from STL, however, is one single mesh. Of course, in this case, it doesn’t matter much because he has the original file, the STEP, and the STL.

STL files are everywhere. When there’s something to 3D print, it’s probably going to be an STL. Which, as long as the model is good just as it is, is no trouble at all. But sooner or la… ...

The most popular design file format is the STL file. And although it’s not very tricky to create high quality STL files for 3D prints, it’s not easy as well.

STL files: STL files created by most major CAD systems execute without any glitches. A few off-brand CAD programs do indeed create STL files that have problems, however.

Microsoft has picked up Netfabb's 3D file cloud repair service, and renamed it Microsoft Model Repair. Features faster repair times thanks to new servers.
