The following are the reasons for the conversion from OBJ to STL.įor 3D printing: Almost all 3D slicing software and 3D printers support files in the STL format, while OBJ is not as popular or universally accepted. This is often due to the compatibility issues related to the OBJ format, as it is not as widely supported as the STL format by various software, 3D printing websites, and 3D printers. Whether you are a digital designer or a 3D maker, you may encounter the need to convert OBJ to STL. This blog will provide three useful methods for converting OBJ to STL format, ranging from online to offline solutions, including web converters, 3D slicers, and CAD software.

Currently, simple and widely accepted STL formats are often the most suitable for 3D printing. However, all the information stored in OBJ is not entirely essential for 3D printing. OBJ can support polygons for curved surfaces and can store color and texture data, and these features cannot be achieved with STL. An STL file describes the surface of a 3D model through a series of connected triangles, while OBJ files are more flexible and detailed. In the field of 3D printing, both STL and OBJ are common and important 3D printer file formats for 3D models.
