Best Free FBX to STL Converter Software for Windows

Here is a list of Best Free FBX to STL Converter Software for Windows. FBX (Filmbox, developed by Autodesk) and STL (Stereolithography) both are 3D file formats that can carry 3D models, designs, information, and more. Using these free software, you can easily convert 3D models from FBX to STL file format. Apart from STL, you can also convert FBX to other 3D file formats including OBJ, DAE, PLY, X3D, and some more.

These are basically 3D modeling software, so you can also make modifications to input FBX models prior to conversion to STL. These provide a variety of tools to perform editing on input FBX file, such as generate meshes like sphere, cylinder, cone, curve, etc., insert various 2D/ 3D shapes, rotate, scale, flip, and more. You can also use these software as a 3D model viewer because of various view and analysis tools present in them. These view tools include pan, move, different side views, camera properties, rendering options, etc.

One of these also lets you batch convert FBX to STL which is a useful feature. You can find a lot more tools and features in these software which may come in handy. Just go through the article to know more about these software.

My Favorite Free FBX to STL Converter Software for Windows:

From the list, I really liked Blender. It is a professional 3D content creation software and requires some skills to operate. But, to simply convert FBX to STL, it offers a straightforward approach, so you won’t face any difficulty. Also, you can do a lot more in this software e.g., video editing, 3D animation generation, etc.

You may also like to check out lists of some best free FBX Editor Software, FBX to OBJ Converter Software, and STL to FBX Converter Software for Windows.

Blender

Blender is a free open source FBX to STL converter for Windows, Linux, and Mac. In it, you can simply open an FBX file containing a 3D model and then convert it to various other 3D file formats including STL. The other supported output 3D file formats in it include DAE, PLY, OBJ, X3D, GLTF, and more.

Blender is a popular 3D model and animation maker software. Using it, you can build, animate, render, simulate, and export professional 3D content including models and video. Hence, it provides you the flexibility to modify the model present in an FBX file prior to conversion. To edit FBX file, you can use tools including mesh building tools (plane, circle, UV sphere, cylinder, cone, curve, lamp, and more), insert rigid body, shading, transformation tools (translate, rotate, scale, mirror), animate features, etc. After editing, you can export the FBX model in STL format.

How to convert FBX to STL in Blender:

• Firstly, go to the File menu > Import > FBX option and open an FBX model in this software.
• Now, you can view the model and as mentioned above, you can also modify the FBX model if you want.
• After that, you can convert the FBX file to STL format by going to the File menu and using the Export > STL option.

Additional Features:

You can use it as a video editor as it provides a dedicated video editing mode. It also lets you add VFX to video and create professional videos. It contains several more tools and features which you can explore. But, it surely needs some professional skills to utilize all its features.

Conclusion:

It is one of the best free software to view, edit, and convert FBX models to STL and other formats.

Bforartists

Bforartists is another open source FBX to STL converter on this list. It is available for platforms including Windows, Mac, and Linux. You can easily open and convert FBX to STL using its import and export features.

In terms of GUI and working, it is almost similar to the above discussed software called Blender. It is used for building 3D models and animations. It offers a lot of 3D CAD design tools which mainly include join, shading, generate meshes, translate, scale, rotate, mirror, duplicate, insert annotations, etc. Using these tools and features, you can also edit the imported FBX file before converting it.

How to convert an FBX 3D model to STL format in Bforartists:

• First, use its Import > FBX option from the File menu to open and view an FBX file in it.
• Next, you can make adjustments and modifications to the input 3D model using available tools.
• At last, you can proceed with the conversion process by clicking the Export > STL option from the File menu.

Other than STL, you can also convert FBX to DAE, 3DS, PLY, OBJ, and other formats.

Conclusion:

It is another good software that lets you convert an FBX model STL and some other 3D file formats.

NuGraf

NuGraf is yet another free FBX to STL converter for Windows. With the help of this software, you can not only convert one but multiple FBX files to STL format at once. If you want, you can also open one FBX file in it, view and analyze the 3D model, and then convert FBX to STL. Apart from STL, it supports various other 2D and 3D file formats including OBJ, PLY, SLDASM, IGES, DWG, DWF, 3DS, STP, etc.

How to batch convert FBX to STL in NuGraf:

• Launch this software and open its File > Batch Convert > 3D Model Files tool.
• Now, add all the source FBX files that you need to convert to STL.
• Next, select the output format as STL and setup export options including line terminator type, flip geometric normals, binary output, etc.
• After that, provide output STL files’ location and then hit the Convert Files! button to start batch FBX to STL conversion process.

Limitation:

In the free version of this software, it doesn’t export every 5th polygon in output.

Conclusion:

It is the only software on this list that can batch convert FBX to STL and a lot more other formats.
