As Microsoft taught us it's all about the *interfaces* or the file formats
So the question is will Motorola release the specs for the various interfaces in the design and do other mfgs (or other 3d printer designs) allow parts to be made to those tolerances?
The implications are a)3D systems have done significant development work on printable parts tech in terms of resolution, ink properties etc. IE no one else can make parts this good, and you can't buy or make a printer to do so currently. b)They will let others use the tech to make parts but not parts to plug into the Motorola design or in fact any mobile phone design (until the agreement expires)
Of course if you come up with a neat idea and then tell the community of makers "Nah, nah, you can't play with our platform" you're likely to p**s them off quite a bit.
Interfaces can be reverse engineered.
Once it is known that it's possible to make parts of certain tolerances and properties it's possible to find other ways to duplicate those properties.
TBH the design might be ok but the planning behind it seems kind of dumb.
