WHICH FILE TYPE SHOULD YOU USE WHEN 3D PRINTING?

3D printing is a process that allows users to create three-dimensional objects from digital files. In order to produce a successful 3D print, it is important to use the correct file format for your printer. In this article, we will explore the most commonly used file formats in 3D printing and their characteristics.

STL: The most commonly used file format in 3D printing is the STL (Standard Tessellation Language) file format. STL files are created by breaking down a 3D object into small triangles or facets, creating a mesh of the object. This mesh represents the surface of the object and can be printed layer by layer to create a physical object.

While STL files are easy to create and widely used, they have some limitations. For example, STL files do not include information about color, texture, or material properties. Additionally, they may not accurately represent curved or organic shapes.

OBJ: The OBJ file format is another commonly used file format in 3D printing. Similar to STL files, OBJ files represent a mesh of an object. However, OBJ files include information about color, texture, and material properties. They also offer improved accuracy for curved or organic shapes.

While OBJ files are a great option for printing objects with color and texture, they can be large and complex. This can make them difficult to work with, especially when creating highly detailed objects.

AMF: The Additive Manufacturing File Format (AMF) is a relatively new file format that has been specifically designed for 3D printing. Unlike STL files, which only include surface information, AMF files include volumetric information, allowing for more accurate and complex object representation.

AMF files can include color and texture information, as well as material properties, making them ideal for creating highly detailed and complex objects. However, AMF files are not yet widely used and may not be compatible with all 3D printers.

Other Formats: In addition to STL, OBJ, and AMF, there are many other file formats that can be used in 3D printing. These include 3MF, VRML, and PLY, among others. Each format has its own set of characteristics and advantages, and the best format for your 3D print will depend on the requirements of your specific project.

Conclusion: Choosing the right file format for your 3D print is crucial to achieving a successful print. STL is the most commonly used file format in 3D printing, but it may not be the best choice for every project. OBJ files offer improved accuracy and the ability to include color and texture information, while AMF files are specifically designed for 3D printing and offer volumetric information. By understanding the characteristics of each file format, users can choose the format that best meets the requirements of their specific project.

At Bowman 3D, we accept almost any 3D printing or CAD file type and have the resources to convert this into the correct file for printing. We also have the ability to reverse engineer parts from an original sample or a legacy drawing. If you have a part you want produced, get in touch with us and we can help with all the technical aspects of getting your part into production.
