10 Best Free PLY to STL Converter Software for Windows

Here is a list of Best Free PLY to STL Converter Software for Windows. PLY (Polygon File Format or Stanford Triangle Format) and STL (Stereolithography) both are 3D file formats used to carry 3D models and designs. To be able to convert a 3D model from PLY to STL file format, you need a software that supports 3D model conversion between these two formats. Hence, I have created this list that contains all those software which can be used to convert PLY to STL. Apart from STL, you can also convert PLY files to OBJ, 3DS, VRML, DAE, and some other 3D file formats.

Almost all these are 3D model viewer and builder software, while one of these is a dedicated batch 3D model converter. Using it, you can convert a whole folder of PLY files to STL format at once. On the other hand, 3D modeling software can be used to view, analyze, and even edit the imported PLY model prior to conversion. The tools provided for editing mainly include mesh building tools, extrude, drawing shapes, scale, rotate, flip, translate, and many more. In general, these are feature rich software with an additional feature of converting PLY to STL format.

The steps required to convert PLY models to STL format are also very easy to use. You can checkout the software description to know the exact procedure.

My Favorite Free PLY to STL Converter Software for Windows:

Spin 3D Mesh Converter is my favorite software as it is a straightforward software that allows you to batch convert PLY to STL.
