AMF File - Additive Manufacturing File Format for 3D Printing
The Additive Manufacturing File Format (AMF) is a modern XML-based standard specifically designed for 3D printing and digital fabrication. As the official successor to STL, the AMF format enables improved print accuracy, material definition, and advanced printing capabilities for the next generation of additive manufacturing workflows.
Key Features of AMF Files
- Multi-Material & Color Support: Enhance 3D prints with detailed color, gradient textures, and multiple materials for realistic prototypes and final products.
- Efficient Geometry Reuse: Save space and improve speed by referencing repeated geometry instead of duplicating mesh data.
- Compression Ready: Supports ZIP-compressed AMF files to reduce file sizes while preserving model fidelity and print quality.
Convert AMF Files to STL, OBJ, 3MF, and More
Convert AMF to STL, OBJ, DAE, 3MF, and SKP using our powerful tools: Autoconverter and Automesher Application. These solutions use the open-source Asset Import Library (Assimp) to ensure wide compatibility and robust support for 3D file formats. Whether you are prototyping or producing final parts, our AMF file converters deliver the reliability you need for modern 3D printing and CAD workflows.
CityJSON (3D City Model) File
The CityJSON file format is a modern, JSON-based (JavaScript Object Notation) standard designed for storing and exchanging 3D city models. It efficiently encodes buildings, roads, bridges, urban furniture, and other city objects, offering strong support for textures, semantics, and detailed metadata. CityJSON is a lightweight alternative to CityGML, optimized for simplicity, web integration, and high-performance applications.
Key Features of CityJSON Files
- JSON Simplicity: CityJSON files are lightweight, human-readable, and easily parsed by common programming languages, avoiding the complexity of XML structures like in CityGML.
- Semantic Data: Preserves rich metadata, including building heights, roof shapes, material classifications, and road types, enhancing 3D GIS and urban analysis.
- LOD (Level of Detail) Support: Manages multiple levels of detail (LOD1 through LOD4) to suit diverse visualization, simulation, and analysis needs.
- Web-Friendly Format: Perfect for 3D web visualization and integration with JavaScript libraries like Cesium and Three.js.
- Open and Extensible: Developed by the 3D Geoinformation Group (Delft University of Technology), CityJSON is an open standard that promotes interoperability and innovation.
- File Extension Note: Both CityJSON and GeoJSON use the .json extension - ensure you verify the file structure before processing to avoid errors.
CityJSON File Conversion Made Easy
With Autoconverter and Automesher Application, you can seamlessly import, export, and convert CityJSON files into formats like STL, OBJ, SKP (SketchUp), and 3DS. Our tools preserve geometric precision and semantic information, making it easy to integrate 3D city models into your CAD, GIS, and 3D visualization workflows.
