Migo is an internet-enabled 3D printer with an aluminum shell, WiFi, built-in camera, OLED screen, and a whole host of convenient features in a compact body. It weighs only 2.5kg, so you can take it with you anywhere. It can print in 100 mm/s to 200 mm/s resolution.
MakeX is behind the project. As it turns out, they have also made a backpack for this 3D printer, so you can take yours with you everywhere you go. You can find this project on Kickstarter.
