Plug in your 3Doodler 3D Printing Pen and give it about a minute to warm up. Then insert a strand of plastic into the back. There are two arrows and thus two speeds. Press the speed of your choice, and watch the plastic flow out of the 3Doodler 3D Printing Pen. And then you just draw and connect and fill in and make magic happen. Wanna switch colors mid build? Just push both buttons and the plastic will eject out of the back. Slip in another color, print out a little bit (as the colors blend from remains of old color into new color, and then get back to drawing. You're too talented to just draw in two dimensions - kick it to the next level with the 3Doodler 3D Printing Pen.
