File format information for AI and STL

Full NameAdobe Illustrator
Mime Typeapplication/octet-stream

An AI file, short for Adobe Illustrator file, is a proprietary vector graphics format developed by Adobe Systems. It is primarily used by Adobe Illustrator, a popular software application used by graphic designers, artists, and illustrators to create and edit vector-based artwork. Unlike raster images that use pixels, AI files are composed of mathematical equations that define lines, shapes, and colors. As a result, AI files can be scaled infinitely without losing image quality, making them ideal for various applications such as logos, illustrations, and print designs.

AI files store various design elements in separate layers, allowing users to easily manipulate individual components of the artwork. The format also supports a wide range of tools and effects, empowering designers to create intricate and sophisticated visuals. Moreover, AI files are compatible with other Adobe Creative Suite applications, enabling seamless integration between different software for a more efficient design workflow.

Due to its proprietary nature, AI files can only be fully opened, edited, and saved using Adobe Illustrator. However, Adobe provides options to export AI files to more widely used formats like PDF, EPS, and SVG for sharing and collaboration with non-Illustrator users, ensuring the versatility and accessibility of the artwork across various platforms and devices.

An STL file, short for Stereolithography, is a widely used file format in 3D printing and computer-aided design (CAD) applications. It serves as a standard method to represent the surface geometry of a three-dimensional object. The format was first developed by 3D Systems in 1987 and has since become a fundamental file type in the additive manufacturing industry. STL files are essential in the process of converting digital 3D models into physical objects through 3D printing technology.

STL files consist of a collection of triangular facets that approximate the shape of the 3D model. The surface of the object is divided into numerous small triangles, forming a mesh representation. Each triangle is defined by three vertices in 3D space and possesses information about its orientation and size. Since STL files store only the outer surface of the model, they are often referred to as "mesh" files or "surface" files, as they lack information about the object's internal structure or color.

When using STL files for 3D printing, slicing software processes the 3D model by dividing it into layers and creating the instructions for the 3D printer to build the object layer by layer. Despite its simplicity and widespread usage, STL files have some limitations. They do not support color or texture information, and the triangle-based representation can lead to larger file sizes and reduced accuracy compared to other file formats. Nonetheless, STL remains a vital format in the 3D printing ecosystem due to its simplicity and compatibility with a wide range of 3D printers and software.

Information for converting from AI to STL

Our AI converter will convert your AI file to a 3D model using the Heightmap process whereby 2D pixels, based on their luminosity, are converted into 3D space to create a full 3D STL model ready for download for further processing in your favourite 3D editing package or for printing on a 3D printer.
