A 123DX file is a specific type of computer file format commonly associated with 3D modeling and design. It is primarily used in the context of 3D printing and rapid prototyping technologies. The "123" in the name refers to its origin from the software company Autodesk, which developed a suite of tools for 3D design and modeling, including Fusion 360. The "DX" stands for "Data Exchange," indicating its purpose as a file format for exchanging 3D design data between different software applications.

123DX files store detailed information about the geometry, topology, and material properties of 3D models. They can include data about the size, shape, and positioning of objects in the virtual space, as well as information on textures, colors, and other visual aspects of the design. This comprehensive data allows 3D printers and other related software to accurately interpret and recreate the model in physical form, layer by layer.

With the rise of 3D printing and its applications in various industries like manufacturing, healthcare, and architecture, the 123DX file format has become increasingly popular due to its versatility and compatibility with multiple design software platforms. Designers, engineers, and enthusiasts can share their creations easily using 123DX files, ensuring that their innovative ideas can be brought to life with precision and accuracy.

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.
