> Speaking to Dezeen in New York last month, Bitonti said that the 3D-printing industry needed to open up its intellectual property so that the design and manufacturing community could help drive forward improvements.<p>> "They've got to open up," he said. "It's not that they need to open up all of their IP, but it's a lot of things. You see a lot of tinker toys because they're treating it like a copy machine. I think they need to change their mind and understand that it's a manufacturing technology."<p>> He added: "The industry is just completely choked by intellectual property law right now."
