Convert STL to OBJ – The Best STL to OBJ Converter Tools

How close you are to print your file? If it’s just a matter of incompatible file format, why not convert your file right away from STL to OBJ? The task is pretty simple and easy to accomplish.

Understanding that surge in additive manufacturing applications, the support for different CAD file formats has increased too. However, often the 3D printers aren’t compatible with all those alternatives. And, in case your machine does not work with an STL file, why redo the complete design.

Yes, you have heard it right. Just by converting your file to the desired format such as OBJ, you can right away start your print in a matter of time.

So, how does that work in the first place? Well, it is as easy as a cakewalk. You only need the STL to OBJ converter tool. But hey! Not just any converter.

It is imperative to trust the one that does not attack the quality of your design. Because, at the end of the day, what matters is a nice-looking 3D part coming out of your own imagination.

And, that is possible if you know which converter to choose. But if you do not know, we are here to help. The list below points to some of the most intuitive and popular converters that would make your job hassle-free. So, without wasting our time, let’s jump to the best choices.

List of best STL to OBJ Converter Tools

Stereolithography, abbreviated as STL is a CAD file format. The file includes 3D models’ design and graphics for further action such as 3D printing.

But STL is not the only file format available. One another common alternative is OBJ (Object file) which works in a similar fashion. It too carries 3D designs.

Hence, if you are in need of an OBJ file, but have access to STL format, you just need to make use of the converter tool. Also remember, these tools will also help you convert STL files to other popular formats such as 3DS, GLB, DAE, AMF, 3MF, and more. So, let’s begin!
