3D printing has made it easier to bring new ideas to life. You don’t always need a big 3D printer to start prototyping. Take the CoLiDo Pen for instance. It is a 3D printing pen that lets you bring your design to life by drawing it. The device is portable and light. It has fast and slow modes. The print-head has a stable temperature throughout the process and slides up when the 3D Pen is not in use.
