No one has ever imagined that the artist who draws paintings on the paper can now do the drawing in the air. Your reaction to the line should be like that: Is it real? Seriously? Yes, it is possible now and there is no doubt in it. The products with which you can perform this unbelievable task are now in the market. Anyone can buy it. And the price is also cheap.
Any one reading this article will be thinking that how is it possible to draw in the air. I mean how a paint or any material can remain suspended in the air. So let me explain this marvellous product to you. Now it is the time to satisfy your curiosity and answer all of your doubts and questions. That product is 3D printing pen.
3D versus 2D
First, the thing is that we can't draw the 2-dimensional figure in the air. 2- Dimensional figure or drawing is only possible on the paper. But in the real world, all the objects are 3 dimensional. On papers, we draw 2- dimensional objects with pencils. But in the air or space, all the objects are made with 3 dimensions. So definitely to make anything in the space we need to have 3 dimensions.
Another miracle of technology- 3D pen
Engineers researched and their researches bore fruit in the form of 3D pen. The difference between the simple pen and this pen is that the former uses ink while this one uses special kind of plastic. The pen works in the same way as the glue gun does. Plastic is fed to the pen. There is a heater in the pen which melts the plastic to a certain temperature and when we press the trigger, the melted plastic is released through the nozzle of the pen. But the plastic is not in a pure liquid form. Rather it is in a semi-solid form. And the special quality of this plastic is that when it comes out of a pen, it cools and solidifies in a matter of microseconds. So the plastic doesn't flow like a liquid after coming out of the nozzle, rather it stands like a solid wire.
Plastic used in the pen
The plastic used in it is a special type of plastic. It is called ABS plastic. It comes in various colours and textures to fully satisfy your imaginative and creative talent. The plastic after coming out from the nozzle immediately solidifies and forms a solid object. The pen works in the same way as the 3D printer works. In the 3D printer, you design the object on computer aided designing software. The software generates a command file of the product and the commands are sent to the 3D printer and the printer makes the object. The plastic is melted by the heating filament at the tip of printer's nozzle. Hence, both 3D pen and 3D printer works in the same way. The difference is that 3D printer is automated whereas 3D pen is not automated and is used manually.
Types of 3D pen
There are two types of 3D pens. Both have their own features which I am going to describe. You should decide about one of them after comparing your requirements with the features.
3D pen with the hot element
The pen basically follows the working way of hot glue gun. The plastic is melted by the hot nozzle. And the plastic solidifies after coming out of the nozzle. This awesome device can satisfy all of your imaginative and creative needs. It can be used to unleash a hidden artist in you.
Ink pen
The pen doesn't have a hot nozzle and so there is no chance of roasting your finger tip or a hand accidentally. This type is safe for children and they can easily use it without adult supervision.
Which brand should I buy?
The technology of 3D drawing and printing is not new. It is pretty old now and the markets and online shops are flooded by the varieties of 3D pens and printers. There are many companies who are manufacturing and marketing them. You must be confused that which pen you should buy because there is a large variety in the market. Just check the features of every pen available in the market and compare them. Do check the cost if you are tight on budget. Big thanks to the social media, search the brand's Facebook page and compare the reviews. You can easily decide on that method.
