What are the OBJ and STL files used for?

What is an STL file commonly used for?

STL is a file format commonly used for 3D printing and computer-aided design (CAD). The name STL is an acronym that stands for stereolithography — a popular 3D printing technology. You might also hear it referred to as Standard Triangle Language or Standard Tessellation Language.

Is OBJ file the same as STL?

With the development of multicolour and multi-material printing, the file format was later adopted by the 3D printing industry. In terms of popularity, OBJ is second only to STL. However, unlike STL which only stores geometry data, OBJ can store geometry, colour, texture, and material data.

Why are STL files used for 3D printing?

This format uses a series of linked triangles to recreate or reproduce surface geometry of the 3D model. The more triangles used, the higher resolution the 3D model will have. STL file is widely used because it is simple, light and easy to be handled by 3D machines and software.

Is OBJ or STL better?

In terms of geometry description, OBJ is more capable than STL, as it can describe “real” curves, without the need to approximate them to a series of polygons.

What does an STL file contain?

An STL file describes a raw, unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system.

What does OBJ file stand for?

An OBJ file is a standard 3D image format that can be exported and opened by various 3D image editing programs. It contains a three-dimensional object, which includes 3D coordinates, texture maps, polygonal faces, and other object information. OBJ files may also store references to one or more .

Which 3D format is best?

3ds is one of the best 3D file formats when it comes to drawings and objects. Since the 3DS format is understood by virtually all 3D-related software, such files can be opened or imported with a large number of tools. The main areas of use are architecture, engineering, education, manufacturing.

Can you convert STL to SVG?

You can convert your STL documents from any platform (Windows, Linux, macOS). No registration needed. Just drag and drop your STL file on upload form, choose the desired output format and click convert button. Once conversion completed you can download your SVG file.

Can Cura open STP files?

This article describes how to open native CAD files directly in Ultimaker Cura instead of STL or other 3D file formats. This provides a more streamlined workflow for engineers and improves productivity.

List of supported applications and file types.

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.

Can AutoCAD open STL files?

While some CAD programs are able to import STL files, AutoCAD users will know that it isn’t possible with this software. DWG is the native file format of AutoCAD that can store both 2D and 3D data. It’s highly compatible with other CAD software, making it one of the most commonly used formats around.

Do all 3D printers use STL files?

The most common and universal file formats for 3D printing are STL and VRML. STL stands for “stereolithography” – it is a 3D rendering that contains only a single color. This is typically the file format you would use with desktop 3D printers.

Does AutoCAD support OBJ?

Right now, AutoCAD cannot read an . obj file directly. Please use Autodesk 3DS Max to create the . dwg file from the OBJ file.

Can a 3D printer print STL?

The STL (Standard Triangle Language) is the industry standard file type for 3D Printing. It uses a series of triangles to represent the surfaces of a solid model. All modern CAD (Computer Aided Design) software allow you to export their native file format into STL.

Can you 3D print a OBJ file?

The OBJ file format absolutely supports multi-color 3D printing. The standard 3D printing format STL does not support colors, and the other 3D printing formats like AMF, 3MF, and VRML are too fringe to consider for mainstream use.
