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.

An IDTF (Intermediate Data Transfer Format) file is a type of 3D model file format used for transferring 3D models between different software applications and platforms. It acts as an intermediary format that helps bridge the gap between various modeling programs, enabling efficient data exchange without losing essential geometric and texture information. IDTF files are commonly used in the context of 3D graphics, computer-aided design (CAD), and 3D printing applications, where interoperability between different software is crucial.

Unlike native file formats specific to certain software, IDTF files are designed to be relatively simple and universally understandable, making them an ideal choice for cross-platform collaboration. They typically contain geometry data, texture coordinates, material properties, and other relevant information needed to represent a 3D model accurately. As a result, IDTF files facilitate smooth data transfer between modeling software, enabling designers, artists, and engineers to work seamlessly across different tools and workflows.

One of the popular uses of IDTF files is in combination with the Interactive Data Language (IDL) platform, which is commonly used for scientific visualization and data analysis. IDL can read and render IDTF files, making it an efficient tool for visualizing complex 3D models and datasets from various sources. Overall, IDTF files play a vital role in streamlining the 3D content creation process, fostering collaboration, and ensuring compatibility across diverse software ecosystems.

Information for converting from STL to IDTF

Your STL file will be converted to a IDTF file using our unified 3D model and mesh conversion tool. Our STL 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals and relevant material information. As STL supports color materials and IDTF does not, our tool will not attempt to transfer any color information, your final 3D model will contain geometry data only.
