Sounds interesting, but I didn't quite get the idea of implementing blockchain in that. Can you explain?
It sounds like the blockchain is implemented as a way of distributing or running the slicing process in parallel. So, make a process that already takes almost no time at all and try to make it faster, for a physical process that is measured in hours.
Right, blockchain allows to decentralize the slicing process, makes it cheaper and faster. Also, using blockchain it will be possible to protect the copyright on 3D models.
