Its smaller size makes it perfect for storage and quick sharing, but overall, STL is limited to 3D printing purposes. The more complex OBJ, in contrast, is traditionally used for applications other than 3D printing, including those that require further modeling and editing.
Is OBJ file the same as STL?
STL files store objects as sets of vertices joined by edges to make triangular faces. OBJ files store 3D information as a list of vertices joined by edges, and unlike STLs, they support polygonal faces that allow for a closer representation of the original geometry.
What is STL best for?
This file format is supported by many other software packages; it is widely used for rapid prototyping, 3D printing and computer-aided manufacturing. STL files describe only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes.
Is OBJ a good file format?
The OBJ file format is one of the more important file formats in both 3D printing and 3D graphics applications. It is the preferred format for multi-color 3D printing and is widely used as a neutral interchange format for non-animated 3D models.
Are STL files problematic?
Although STL is the most widely used file format for 3D printing, it also has its own limitations. STL only understands the external surface and shape of the 3D model. The second biggest problem regarding STL files is the gaps and overlaps of joining surfaces in model that are not drawn correctly.
Is step better than STL?
STL files are more storage-efficient than STEP files but lack the customization and the after-download editing that STEP files offer. If you want the best of both worlds, it’s straightforward to convert a STEP file to STL, and also possible to convert back the other way.
How do I convert STL to OBJ?
One of the most straightforward ways to convert an STL to OBJ is to use an online converter. There’s many to choose from, such as MeshConvert or Greentoken. These sites let you upload an STL file from your computer, pick an output format (OBJ) and then download the converted file.
What contains OBJ file?
The OBJ file format is a simple data-format that represents 3D geometry alone — namely, the position of each vertex, the UV position of each texture coordinate vertex, vertex normals, and the faces that make each polygon defined as a list of vertices, and texture vertices.
What are the most common 3D printing file formats?
STL is the most common file format when 3D printing. STL stands for STereolithography and . STL files consist of facet data. STL is a standard file format that can interface between most CAD software and 3D printers. .
What is G-code in 3D printing?
G-code is a language that humans use to tell a machine how to do something. With 3D printing, g-code contains commands to move parts within the printer. G-code consists of G- and M-commands that have an assigned movement or action. … You create a g-code by slicing a file in Cura and saving it.
What is STL and OBJ files?
STL files don’t display any data on the surface of the mesh. … OBJ files, on the other hand, incorporate the actual photographic imagery captured by the camera while you’re scanning and map it onto the surface of the polygons contained in the mesh.
Why is OBJ format so popular in the industry?
The biggest strength of the OBJ file format (and its sister MAT material definition file format) is that it is text-based and very simple to understand. As a result of its simplicity, it is usually the first format that any 3D tool imports and exports.
What software can open OBJ files?
Files in OBJ format can be opened with Autodesk Maya 2013, Blender, and MeshLab in Microsoft Windows, Mac OS, and Linux platforms.
