How to Convert STL to OBJ: A Complete Guide

May 22, 2024

So you've created a 3D model in STL format, but now you need to convert it to OBJ for further editing or rendering. Fortunately, the process is quite straightforward, and this guide will walk you through the steps to successfully convert your files.

First, let's understand what the STL and OBJ formats are. STL (Stereolithography) is a file format commonly used for 3D printing and computer-aided design (CAD), while OBJ (Object) is a more versatile and widely supported format for 3D modeling and animation.

To convert your STL file to OBJ, you will need to use a file conversion tool or software. Many 3D modeling programs offer built-in export options to convert files between different formats. If your current software does not support OBJ export, you can use online conversion tools or dedicated file conversion software.

One popular method is to use MeshLab, a free and open-source 3D mesh processing software. MeshLab allows you to import your STL file and then export it as an OBJ file with just a few clicks. Simply open your STL file in MeshLab, go to File > Export Mesh As, choose OBJ as the file format, and save the file to your desired location.

Another tool that is commonly used for file conversion is Blender, a powerful and free 3D modeling software. Blender provides extensive support for importing and exporting various file formats, including STL and OBJ. To convert your STL file to OBJ in Blender, simply import the STL file, make any necessary adjustments to the model, and then export it as an OBJ file.

If you prefer a web-based solution, several online file conversion services offer the ability to convert STL to OBJ. Websites like Convertio, AnyConv, and Online 3D Model Converter allow you to upload your STL file and then download the converted OBJ file directly from their platform.

Keep in mind that during the conversion process, some details or properties of the 3D model may be lost or altered. It's essential to review the converted OBJ file in your 3D modeling software to ensure that it meets your expectations and requirements.

In conclusion, converting STL to OBJ is a simple and essential task for 3D modelers and designers. Whether you use dedicated software like MeshLab or Blender, or opt for online conversion services, you now have the knowledge and tools to successfully convert your files. Make sure to test the converted OBJ file to ensure that it maintains the integrity of your 3D model and make any necessary adjustments as needed.
