OBJ builds on the STL file with multiple colours and material data. STL in that it contains 3D geometry information alone, such as vertex normals, geometric vertices, polygonal faces and texture coordinates. It is widely supported by 3D printers (such as the Formlabs 1+ and 2) and most software will export to. OBJ is the second most common file format used in 3D printing. STL is a standard file format that can interface between most CAD software and 3D printers.STL files contain only a single colour (an obvious limitation) and they are a triangular representation of a 3-dimensional object.ĭespite the rudimentary data contained in an STL file, STL is the most popular file today.
STL is the most common file format when 3D printing. Below, you will find out everything you need to know about the most common file types used in the 3D printing industry.STL Some file types are proprietary to 3D printer manufacturers some are related to design software, and some are generated by 3D scanners. When you are designing 3D models, you will likely encounter a few different file types.
So, we thought we’d write an article about this.
He wanted to know what the most common file formats are and how they are used. We recently received a question from a student in secondary education regarding file formats and 3D printing. This article has been updated for 2021 with new information.
