The 3D Printing Pen

World is turning into 3D day by day, what you say? But still their are lot of inventions are still waiting for us right? How about an astonishing name 3D Printing Pen. Come September, if everything goes to plan, the world’s first 3D printing pen will go on sale for $75. The pen, called the 3Doodler, essentially allows you to lift your flat sketches off the paper — or, if you wish, to actually draw in three dimensions.


3Doodler is a Kickstarter project, and in under 24 hours it has obtained more than $500,000 in pledges — significantly more than its $30,000 target. As you can see in the video below, the inventors have already created an impressive prototype — and now it’s time to bring the 3Doodler to market. The target price is $75 for a September 2013 release. The inventors say they have already located a Chinese manufacturer who is capable of meeting these targets. The final device should 24mm (1in) thick and weigh less than 200g, with an external power brick that accepts 110-240V.

In essence, 3Doodler is a standard 3D printer, but your hand controls the print head instead of a bunch of computer-controlled motors. (See: What is 3D printing?) Inside the 3Doodler is a filament feeder (which accepts ABS or PLA plastic), a heating element, and an extruder — and that’s about it. The melted plastic comes out of the extruder and very quickly sets. As far as we can tell, the plastic oozes out of the extruder at a set rate — so depending on whether you want a thin (weak and flexible) or thick (strong and rigid) line, you move the 3Doodler quickly or slowly. For strength and flexibility, you just go back and forth over the same section, building up a web of plastic tendrils (like in the Eiffel Tower above).

Go get one.
