There are plenty of large, sophisticated 3D printers around. You don’t need the biggest 3D printer to start printing your objects though. Take Baby 3D for instance. It is a compact 3D printer that you can hold in your hand and take with you. It has a lightweight, portable design. The Baby 3D printer is compatible with open source software. It has an open, customizable design.
Such a small printer could prove useful for people who don’t have space for a large printer or would like to get their kids or students familiar with 3D printing. The product is getting funded on Kickstarter.
