An OBJ file that uses approximate coding generates a simplified version of the model’s surface through tessellation, as it happens with a STL.This means that, using an OBJ we can capture the “original” geometry of the model, not an approximation built from triangles. Instead, it will preserve the original geometry of the model using three-dimensional lines known as NURBS (Non-uniform Rational B-spline). An OBJ file that uses precise coding will not tessellate the model into triangles, as an STL does.This format is much more complex and has several modes of operation: precise mode and approximate mode: The OBJ format, although less known than STL, is also very popular and almost any software related to design or 3D printing supports it. This format is, nowadays, the most used to share models for 3D printing, although it is definitely not the best, since there are more modern formats that use less space and add more information. In spite of being lighter, binary STLs still are too big if we want to give a lot of resolution to an object, since we will need to include many triangles. There are several nuances in the operation of each, but keep in mind that the binary STLs are somewhat smaller and appeared as a response to the increasing size of the ASCII STLs. There are several STL file types, but the most common are ASCII and binary.
