It’s hard to believe that we’ve actually reached the point where 3D printing technology is so accessible to consumers that even children can use it. Mattel proved this with its new ThingMaker, which was originally a device that allowed children to create their own plastic molds back in the 1960s, but is now a $300 3D printer that allows children to design their own toys through an Android or iOS app, and then print a physical version of them. Obviously there are a few safety measures to ensure that the children don’t hurt themselves, but the device is geared towards children aged thirteen and older, so most of them should have enough common sense not to hurt themselves, but you can never be too careful with kids.
