Here are 2 simple steps to convert your U3D to STL using our fast and free U3D converter tool.
| Extension | U3D |
| Full Name | Universal 3D |
| Type | 3D Model |
| Mime Type | model/u3d |
| Format | Binary |
The U3D file is a 3D file format (Universal 3D) developed by a consortium of well known companies in 2005 with the idea of creating a standardized file format for storing 3D data including mesh vertices, textures, bones and effects.
U3D files are binary in nature containing a block based structure which following later revisions could be extended with custom blocks.
U3D Converter Capabilities
Our U3D 3D Model/Mesh tool does not support any color material data contained within U3D files so the converted file will not contain any color information.
| Extension | STL |
| Full Name | Standard Triangle Language |
| Type | 3D Model |
| Mime Type | application/vnd.ms-pki.stl |
| Format | Text |
| Opens With | Blender, MeshLab, CAD Assistant, DAZ Studio |
The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.
There were several formats that attempted to extend the STL format namely SolidView and VisCAM whose formats included limited 15-bit color information for each mesh face which is often ignored by most modern 3D software. The STL format can be either Text or Binary, our tools will support both formats.
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 U3D file will be converted to a STL file using our unified 3D model and mesh conversion tool. Our U3D 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 U3D file, your final 3D model will contain geometry data only.
First click the "Upload..." button, select your U3D file to upload. Your U3D file will be uploaded to our servers. When the U3D to STL conversion has completed, you can download your STL file straight away.
We aim to process all U3D 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.
