Positioning of 3MF in V-Model


There are currently 16 Founding Members and 10 Associate Members within the 3MF Consortium.

The 3MF File format is not intended to be standardized by a standardization body.

Relevance and Benefit for MBSE

  • quasi industry STD
  • flexible format for all AM information

Risks and Impediments

  • Development efforts need to be split among several FMI versions, slowing down overall adoption rate of the standard
  • Users keep using older versions of the standard; therefore tool vendors have no incentive to implement newer versions for export
  • Releases of non-backward compatible versions cause transition overhead for users, slowing down the adaption of new releases
  • A simulation model using multiple FMU's from different IT tools may not leverage the full FMI capabilities if one (or more) IT tool(s) do not support all capabilities of the FMI specification. This can lead to unexpected simulation results.
