So what does this mean?

Our member and longstanding supporter of all things innovation, Microsoft, has announced that they will be sunsetting our free tool, The 3MF Service. The 3MF Service helps users by automatically preparing their 3D files for 3D printing; users have to upload 3D files, select a tool, then download a ready-to-print 3MF file. It’s easy to use, and while we’ll be sad to see it go, we’re happy to report and share other tools that work similarly and convert your files to 3MF quickly and efficiently!

About 3D Builder

The 3D Builder app has modeling and editing tools and the ability to print to a Windows-compatible printer driver-equipped 3D printer. The app can be used as a reference and a test tool for 3D editing and for validating the 3MF files you create. You can download many kinds of 3D files, including 3MF, STL, OBJ, PLY, and VRML file types, and it can save models in 3MF, PLY, and STL file types.

About 3D Printing SDK

Microsoft’s 3D Printing SDK offers a collection of tools for Windows to facilitate the development of 3D printers and apps. This collection includes:

  • The 3D Manufacturing File format (3MF) specification and sample 3MF files
  • The full source code shows 3D printing from the Microsoft Store and a desktop application.
  • Sample 3D printer drivers.

Most notable — and first on the bullet list above — to the 3MF Consortium are the developer docs available to generate a 3MF package. You can learn more here: Generate a 3MF Package.
