OBJ is a 3D model format associated with Advanced Visualizer, a software suite developed by Wavefront Technologies. OBJ files contain geometry definitions of 3D models, including coordinates for each angular point, UV mapping data, texture information and details describing the faces of each polygon. Due to its frequent use, the OBJ format has been borrowed by other 3D graphics applications as well, and is currently seen as an industry standard.
STL is the proprietary format for a computer-aided design (CAD) program developed by 3D Systems. STL is an acronym for Stereolitography, which is a type of technology used for creating prototypes or patterns through 3D printing. An STL file contains a surface representation of such a model, without detailed specifications of aspects such as colours. STL files can only be opened with a limited number of programs.
So, how to change OBJ into STL?
The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. Although it is fast, this software is extremely efficient in managing a wide range of conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert OBJs. But at the same time, it will allow you to apply a wide range of editing options.
Download and Install reaConverter
reaConverter is quick to download, install and launch, and you don't need to be an IT specialist in order to understand in a few minutes how it operates.
Load OBJ Files
Start reaConverter and load all the .obj files you intend to convert into .stl because, as opposed to most free online converters, reaConverter supports batch conversion. So you can save the time and energy you would lose with doing repetitive operations.
Select OBJs from a folder or by drag-and-dropping them directly into the reaConverter window.
Choose Output Folder
Go to the Saving options tab and decide where you want to save new .stl files. You can also spend a few more moments to apply additional editing to the images prepared for conversion.
Select STL as Output Format
Then pick the STL as output format. To help you do this, a series of buttons is conveniently placed at the bottom of the reaConverter window, so you can simply press on the one you need or click Plus button to add new options.
Then simply press the Start button and your conversion will begin in no time!
