The 3MF Consortium (3MF) released two free specification extensions to its 3MF Core Specification 1.1 for general availability. These extensions are the 3MF Production Extension and the 3MF Slice Extension. They will enable high-volume additive manufacturing facilities to better integrate and manage their 3D printing operations.
3MF Production Extension
For high-volume users such as service bureaus, the 3MF Production Extension helps users organize and manage print jobs with multiple parts by keeping them in separate .xml files within the 3MF package. The 3MF package manages the file hierarchy and relationships among the files, as well as keeping unique identifiers for each part instance.
3MF Slice Extension
This extension helps meet the need of additive manufacturing to have software that fully describes a model, retains internal information, color, and other characteristics.
The extensions are available for download.
