What characterizes 3Doodler Start : The plastic that comes out of 3Doodler Start is warm, but not hot. Therefore, after the insert slides out, the child can safely shape it with his hands. 3Doodler Start and the ECO-inserts attached to it have been specially designed to be completely safe for children. Eco-cartridges for 3Doodler Start are made of safe, non-toxic, BPA-free and completely biodegradable materials. When fully charged, 3Doodler Start will work wirelessly for 45-60 minutes. Of course, you can still use it while it's connected to power. How does 3Doodler Start work? Pen nozzle - The plastic that comes out of the pen hardens after a few seconds, giving you time to shape it to perfection LEDs - Red: Cartridge heating, Green: Pen ready for use, Yellow: Pen connected to charging Micro USB port - A place to connect the power supply Cartridge Eject Button - Click once to start, click a second time to stop eject the cartridge. A quick double click will make the cartridge retract. It takes 10-15 seconds for the new cartridge to warm up, after which you can start drawing in 3D Pen launch button - Slide the button to turn the pen on or off. Wait 1 minute for the pen to warm up Place to insert the refill - Select a color and place the refill in the pen, press down until you feel resistance 3Doodler is one of those fantastic ideas that seem so obvious in retrospect that it is hard to believe that they are only now being implemented. The premise is simple: the 3Doodler Start pen draws with a heated ECO-cartridge, which makes it possible to build 3D objects in the same way as a 3D printer, but without creating computer models. The 3Doodler Start pen is extremely easy to use. To start creative play, just put the selected color of the ECO-insert in the guide and after a while your child can start creating. The only limitation is your own ingenuity.
