3D printers are fun to play around with. In fact, you learn a lot about modeling, scanning, and design by using them. Getting your kids started in 3D printing is going to be easier when you have a safe 3D printer available. The Rever aims to be that solution. It has a translucent safety door that lets your kids watch the printing process with the dangerous parts out of their way.
The door opens only after the dangerous parts are locked away. Rever is WiFi enabled and compatible with iOS and Android devices. It uses PLA to print. More information is available on Kickstarter.
