If you’re in the market for 3D printing files, there are plenty of options out there. But before you start downloading, you need to consider what sort of file you’re looking for and what features it offers. Read on to find out.
You can download free 3D printing files from websites such as Thingiverse, Yeggi and MyMiniFactory. Each site offers a different selection of files, and each has its own pros and cons. For example, while Thingiverse is the most comprehensive library of printable files, it may not be the best at spotting counterfeit items.
The most common file format for 3D printers is the STL file. Basically, an STL file is a triangular representation of a three-dimensional object. These files are widely supported and can be used by a variety of programs, including most CAD software. However, there are some limitations, such as the resolution of the model and the number of colours.
The OBJ file format, on the other hand, is a more robust system for describing a 3-dimensional object. OBJ files can be used by virtually any 3D design software, including popular programs like Blender and SolidWorks. This is because the OBJ file format allows for high-quality geometry and colour, plus a texture layer.
In addition to the most basic file formats, there are more complex file formats. For instance, the AMF file format is a highly compressed open standard that’s capable of improving workflows, and there is a new standard of attribution for 3D prints, which can be easily broken apart from the physical object itself.
The Polygon File Format is another file format, which includes a collection of faces and surface details. It also includes a set of RGB colour instructions, which is important for displaying a 3D object with vibrant colours.
The Additive Manufacturing File Format is an XML-based open standard that supports object, material, texture, and metadata. Although this format is a bit smaller than the STL file, it is a more efficient way of storing and exchanging information.
One of the best features of the OBJ file format is that it can be converted to the STL file format. Using an OBJ file is especially useful when you want to use the same design for a colored 3D printer. Many slicers accept OBJ files as input, which means you can have full colour and good geometry with little effort.
Yeggi, while not as extensive as other sites, is still a great resource for downloading 3D printing files. Their website is extremely easy to navigate, making it a breeze to find the file you’re looking for. Moreover, they offer a search engine aimed at finding the best printable 3D models. Some of the best 3D printing file sites offer premium paid downloads, while many of them are completely free.
The FBX file format is another option, which was invented by Kaydara and is a commonly used format in film production. This is because it allows data to be exchanged between several programs, including Autodesk’s CAD software.
