Grow Secure is one of the first--but surely not the last--companies to help deal with intellectual property rights for 3D designers. Their encryption software allows for industrial designers to feel confident in allowing their work to be distributed online, and can even be encrypted so that manufacturers do not have their hands on the original design, but so that they do have specific organized instructions, promoting security and consistency.
