6 Best Free 3DS to STL Converter Software for Windows

Here is a list of Best Free 3DS to STL Converter Software for Windows. 3DS (developed by Autodesk) and STL (Stereolithography) both are 3D file formats used for creating and storing 3D models and data. Now, to be able to convert a 3DS file to STL format, you will need a software which supports these two formats as input and output. To help you out, I have created this list of best free software which let you convert 3DS to STL. So, you can simply go through this article and get a suitable software as per your requirement.

Most of these software let you modify 3DS file before converting it to STL format as they are primarily 3D modeling software. You can use various available tools to edit 3DS files including draw mesh designs, transform objects (rotate, move, scale, etc.), align objects, sculpt, extrude, etc. Plus, you also get a dedicated set of 3D model viewing and analyzing tools in these software.

One of these software is a dedicated 3D file converter using which you can batch convert 3DS to STL. Additionally, these software support many other 3D file formats for the purpose of conversion, such as OBJ, PLY, DAE, STP, FBX, etc. All in all, these software are quite versatile which can be used for many other 3D modeling tasks including 3DS to STL.

My Favorite Free 3DS to STL Converter Software for Windows:

Spin 3D Mesh Converter is my favorite software as it lets you convert multiple 3DS files to STL format simultaneously.

In case you want to edit 3DS model prior to conversion to STL, you can use Wings 3D which is a feature rich 3D model creator.
