A VTK (Visualization Toolkit) file is a popular file format used in scientific and engineering applications to store and exchange data related to 3D visualization. VTK files are designed to represent geometric and visualization information such as points, lines, polygons, and other complex structures, making them ideal for storing data related to 3D models, simulations, and scientific visualizations. These files use a simple text-based format that allows for easy interpretation and manipulation by various software tools and libraries.
VTK files consist of header information, followed by data arrays containing the actual data points and their attributes. The header typically defines the file format version, the data type (e.g., ASCII or binary), and metadata describing the structure and properties of the data. The data arrays can hold information such as vertex coordinates, cell connectivity, scalar values, vector data, and other attributes, enabling the representation of both geometries and associated attributes required for rendering and analysis.
Due to its flexibility and widespread support, the VTK file format has become a standard in the scientific and engineering communities. It is commonly used in various visualization and simulation software, allowing researchers, scientists, and engineers to share and visualize their data seamlessly. Additionally, the VTK format's openness and accessibility have fostered the development of numerous tools and libraries that can read, write, and process VTK files, making it a vital component in the field of 3D data visualization and analysis.

| Opens With | Blender, MeshLab, CAD Assistant, DAZ Studio |
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.
STL Converter Capabilities
Our 3D conversion tool does not support color/material information in STL files so your file will not contain any color information.
Your VTK file will be converted to a STL file using our unified 3D model and mesh conversion tool. Our VTK 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals and relevant material information. Our tool will not attempt to transfer any color information if present in your VTK file, your final 3D model will contain geometry data only.
First click the "Upload..." button, select your VTK file to upload. Your VTK file will be uploaded to our servers. When the VTK to STL conversion has completed, you can download your STL file straight away.
We aim to process all VTK to STL conversions as quickly as possible, this usually takes around 5 seconds however this can be longer for certain files, so please be patient.
We aim to provide the best conversion experience. Our tools are under constant review and development with new features being added every week.
