Convert Your 3D Mesh/Model VRML Files to 3MF

Our free and fast tool will convert most 3D mesh or VRML (Virtual Reality Modeling Language) model files to a standard 3MF (3D Manufacturing Format) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. Our conversion tool can also batch convert multiple VRML files; up to 25 files at a time can be converted.

To convert your VRML file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a 3MF file and will be ready for download shortly afterwards. For more information about the VRML to 3MF conversion process, see the conversion information section below.

How long does it take to convert my VRML to 3MF?

We aim to process all VRML to 3MF conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.

How accurate is the VRML to 3MF conversion?

We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.

Is it safe to convert my VRML to 3MF on ImageToStl.com?

Yes, of course! We do not store the VRML file you submit to us. The resulting 3MF file, once created is deleted 15 minutes after upload and the download link will expire after this time.

Can I convert my VRML to 3MF on Windows, Linux, Android, iOS or Mac OS?

Yes! Our VRML to 3MF tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.

What if I am using an Ad Blocker, will that affect things?

Yes. Although you can use an Ad Blocker, if you like our VRML conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.

I have several VRML files; can I batch convert my VRML to 3MF?

Yes! Our VRML tool supports full batch conversions. You can upload up to 25 and VRML files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the 3MF files individually or download them all in a single ZIP file.

Description

The VRML file format is a 3D-based model format originally created in the 1990's that was aimed at website usage. The format is text-based and contains 3D geometry data such as vertices, faces, simple shapes, material information, and more.

This format, when launched, was hoped to become a standard 3D format; however, due to the large file sizes, it didn't see wide adoption, although it is a supported format within some CAD software applications. It was later superseded by the X3D file format, which shares most of the functionality of VRML files.

VRML Notes

If your VRML file contains textures, these will be ignored. If a material contains color information, this will be translated where possible.

Description

3MF files are a modern 3D file format designed specifically for use with 3D printable models (additive manufacturing). It was designed to be the successor to the popular legacy STL format (also a common format in 3D printing) to overcome the limitations of that format.

The format of 3MF files is XML-based and compressed with standard Zip file compression, resulting in small, easily transferable files. The format supports 3D meshes along with associated materials and textures, all contained within the Zip file.

3MF Notes

3MF files support material and color information. If your uploaded model contains color information, our tool will attempt to save this in the 3MF file at the end of the conversion process. Textures are supported and will be included in the final 3MF file.

Face and vertex colors

Converting Your VRML File for 3D Printing

Software used to prepare a 3D model file for printing, which is also known as 3D slicer software, cannot usually open VRML files. This is because slicer software authors will support the most common formats used for 3D printing, such as STL and 3MF and do not have the resources to implement 3D object parsers for all the possible 3D formats that are out there.

Slicer software can, however, handle files formatted to the 3MF standard. This is because the 3MF format was specifically designed as a medium of storage and exchange for 3D printable models. Our VRML to 3MF conversion tool can convert your VRML file into a 3MF file suitable for loading into most 3D slicer software. As 3MF files support material colors and textures, our converter will convert these if present, resulting in a single 3MF file suitable for use with most 3D slicer software.

How does it work?

Converting from the VRML file format to 3MF can be a complex process, and any tool used for this conversion process needs to be able to handle a variety of data conversion tasks as well as identify any defects within the 3D model and fix them. Here we will explain the conversion process used by our tool to accurately convert your VRML file to a valid 3MF 3D model. Let's start with the conversion process, which involves the following steps:

Step 1: Read the Source VRML File

In its simplest form, an VRML file is a plain text file containing human-readable 3D data such as vertices, faces, normals, and more. When combined, these make up the 3D model you see on your screen.

For more information regarding the VRML file format, please see this great article that goes into a lot of detail explaining the VRML format.

Step 2: Process File Data

With the VRML file data read, our tool generates an internal representation of the full 3D model and will attempt to fix any geometry issues encountered. Along with repairing any issues with the 3D model, the tool will remove any duplicated vertices and prepare the model for exporting to the 3MF format.

⇪

Step 3: Saving to the 3MF Format

The 3MF file format is relatively new and its primary aim is to become the standard for storing and distributing 3D models for 3D printing applications. Most modern 3D printing software can open 3MF files.

Our tool will now take the in-memory 3D model we have created in step 2 and convert this to the 3MF format ensuring it is compatible with any 3D printing software that supports 3MF.
