For color printing, OBJ files are the best choice as they can store more complex information and describe more details using polygons. If you're looking for the easiest-to-use and most commonly used 3D printer file type, STL files are the most suitable as they describe geometry using simple triangles. Which 3D Printing File Format Type Is the Best?Įach file type serves its own purpose and has its differences. Unlike AMF, which has seen slow development and lacked support, the 3MF file format for 3D printing is gradually being widely accepted. Compared to the old STL files from the last century, 3MF can generate more refined and higher-standard 3D models, often with smaller file sizes. It can store all the necessary information for printing 3D models, such as units, scales, colors, meshes, materials, and texture data. The 3MF format was introduced in 2015 to replace the file like. The 3MF (3D Manufacturing Format) is another common file format for 3D printing, specially designed for additive manufacturing and 3D printing, as the name suggests. However, not all software and slicers are compatible with the AMF format type for 3D printing due to its slow development and lack of proper support from most 3D modeling and printing software. The AMF 3D printer format documents can store materials, colors, and other metadata, and optional curved triangles can make smoother geometric surfaces. The Additive Manufacturing File (AMF) format was introduced in 2011 and was initially known as "STL 2.0" with an aim to replace the STL format. Programs like Blender, MeshLab, and Autodesk Fusion 360 are recommended as they can open, view, and edit OBJ file types. Moreover, converting OBJ to STL can be achieved using these software. While not as common as the STL format, OBJ can be an alternative to STL because most slicers, CAD tools, and 3D printers are compatible with OBJ. Additionally, it can store data regarding geometry, colors, textures, and more. OBJ uses not only triangles but also polygons such as quadrilaterals or hexagons to design a 3D model. In contrast to the STL file format, OBJ has been improved to create 3D models with precision and high quality. The OBJ (Wavefront OBJ) file is one of the most common file types in 3D printing. However, it does not contain texture, color, and material data, which limits the model's design and can lead to common issues such as STL files being unable to be sliced. The more triangles there are, the more accurate the model, but also the larger the file. Both 3D model sharing websites and 3D slicers support this type of format.Īn STL file is composed of a series of small triangles to create a 3D digital model. The STL file format is widely used for the creation of simple 3D model designs and is compatible with almost all Computer-Aided Design (CAD) programs to easily generate the STL file format. The STL file is an old file type, developed in 1987 for the first commercial 3D printer. STL stands for Stereolithography, which is the most common and popular file format in 3D printing. This article will discuss the most common 3D printing file format types, detailing what they are, their differences, advantages, and disadvantages. It's advisable to start by learning and using common file types because they are generally compatible with most CAD programs and slicing software. File formats for 3D printing are typically created through CAD software and contain information about the geometry of 3D objects.
