Converting 3MF To STL File Format


The 3D Manufacturing Format (3MF), a Joint Development Foundation project established to develop an advanced 3D printing file format, has announced that 17 companies have adopted its 3MF platform.

“Wide adoption of 3MF is occurring because 3MF is a modern 3D printing file format designed with manufacturing in mind. For additive manufacturing, 3MF completely replaces STL, OBJ and VRML file formats, eliminating many interoperability issues,” said Adrian Lannin, Executive Director, 3MF.

Such companies utilising the 3MF 3D printing format include 3D Systems.

The 3MF Consortium was formed in 2015, to address the issues with currently available file formats to enable design applications for “full fidelity 3D models to a mix of other applications, platforms, services, and printers.”

Designed specifically for the additive manufacturing process, 3MF includes material and properties, production, beam lattice, and slice extensions. The new format contains the necessary model, material and property information in a single archive.

Furthermore, this format provides clear language and conformance tests to ensure a file is consistent from digital to physical. On the other hand, the commonly used STL format exclusively stores information about the vertices and the normal vector of a 3D model.

Converting 3MF to STL

Cimatron CADCAM software can be used to import 3MF files and convert to STL. CDG represent 3D Systems and Cimatron in the UK market.
