This may cause paper-thin walls in 3D printing, which can result in troubles, if the object is not solidified (which, however, can easily be done in tools such as Meshmixer). That means: These objects have just a shell and no filling.

On the one hand, there is CAD software (Computer Aided Design), which is designed for construction, exact measurements and solid modeling.But what if an STL file you downloaded lacks some features, is damaged or you need only a part from it? That’s when you need an STL editor. We show you how to edit an STL file with 5 free STL editors: FreeCAD, SketchUp, Blender, Meshmixer and Meshlab.Įditing STL files can be done in two different types of modeling software: After all: Ready-made STL files are fine. How do I edit STL files? That is something any 3D printer owner sooner or later wonders.
