The printer follows the instructions in the file and creates the 3D object.The data created by the slicer is saved as a Gcode file (the native language of 3D printers), which is sent to the printer.This software creates the instructions for each layer of the object that the printer will generate, the path the printer head will travel while creating each layer, the time it will take, and the amount of material the printer will need.Send the file to a program called a slicer (Slic3r MakerBot Print and Simplif圓D are some examples).3D Printers and OBJ Filesīecause one of the primary uses of OBJ files is 3D printing, understanding how 3D files become 3D objects is key. Other companies have adopted the OBJ format for use in their applications. The file extension OBJ comes from the name Wavefront OBJect (the full name is rarely used). The format was created in the 1980s by Wavefront Technologies for its Advanced Visualizer animation software (Autodesk Maya has since replaced Advanced Visualizer). OBJ is a vector file, which makes the defined objects scalable. The objects in an OBJ file are defined by polygon faces (which themselves are defined by vertexes, or points) and normals, curves, texture maps, and surfaces. OBJ files can support unlimited colors, and one file can define multiple objects. The files are used for exchanging information, CAD, and 3D printing. How a 3D object is defined in an OBJ fileĪn OBJ file (.obj) contains information about the geometry of 3D objects.

How to create, open, and edit OBJ Files.In this guide, we explain how to use OBJ files, how they compare to other 3D formats, and how 3D printing works. We have years of experience with all 3D formats and helping developers expedite their work with AR.
