Hands On 3D Printing

Leave a Comment
3-D Printing Might seem a thing straight out of a Movie. But let me tell you one thing that it was developed in 1980s. It is basically Simple printing but in 3-Dimensions and with different "Ink". The Ink is Usually Plastic but for Bio Printing we use Real Human Cells or we can use Lasers to fuse Resins And Metals. In the past it was only used to print Prototypes for Government but now companies are pushing this Technology to be Commercial. Anybody can create(or print) anything, one can open a industry in his/her backyard. Up till now you could download movies, videos, pictures but now you can download things (or sculptures/blueprints of things).

3Doodler

3Doodler is the most basic type of 3-D Printing. 3Doodler is a 3-D Printer with the shape of a pen. So you can literally Build Castles in the air. This pen uses Rapid Cooling Plastic Cylinders to produce melted Plastic which then cools down to produce a structure in the air. People have already drawn dresses, Jewelries, Science projects etc. You can download the basic models of nearly anything from the 3Doodler website.

Bio-Printing

Bio-printing is basically 3-D printing of Cells and Organs. The organs are printed using a special type of "Ink" called Bio-Ink (a mixture of biodegradable gel and actual human cells). In conventional methods of replacing an organ can be "Rejected" by rejection I mean there might be some sort of compromise like the Blood groups of the donor and the patient may not match, there might be some sort of disability or harmful effect in the organ of the donor. But using Bio printing this problem is diminished as the Bio-Ink used is made up of the cells of the patient. So the phenomenon of Rejection  is basically eradicated. 
We can throw Skin cells at the wound to create a layer of skin over a wound US Military is taking steps to promote the project of "Skin-Printing" for treatment of US Soldiers. 
We can Create Organs like Kidneys, livers, Fingers etc. One such institute is built for this sole purpose named as "Wake Forest Institute for Regenerative Medicine" headed by "Professor Anthony Atala".
We can now create Animal Products - Meat, Skin - Without Animal.
We can now create Organs. First we create a Scalpel using Bio-Ink and then the Human Cells Anchor onto the Scalpel and then create new tissues and cells by Reproduction. After this process the Scalpel can be Removed.

Usage

  • Used to make Suits in Movies. (Iron man Suit in Iron man 2)
  • We can Create Things which are Cheaper than the traditional methods
  • We Might be able to make Houses using 3-D Printing
  • This Technology can be used to 3-D Print Food .Yay!!. by using layers of sugars, grains of food and then putting another layer of water and so on we can Create Food.

Cons

  • The process of 3-D Printing something is very slow. It takes about 3-5 Hours to create a human ear.
  • Usually uses plastic and I think I do not have to list the Draw backs of Plastic.
  • Very expensive
  • Emission of Unhealthy particles into air.
  • Consumption of large amount of energy.
  • You can Create Anything. You can create Guns and Explosives of some kind.

Technology Can Now Give You SixthSense

Leave a Comment
Do you watch movies? Well, I do! Sometimes the science fiction in some movies makes me laugh (out loud) but now it doesn't... Those ambitious fictional scenes can pave way for some really amazing tech. You might have watched movies like The Island, The Matrix, and others with pretty awesome modern technology. MIT has made one of those imaginations a reality. MIT Media Lab's new invention is an awesome wearable gestural interface. It has mixed taste of Google Glass, Augmented Reality and many other hot technologies.

'SixthSense' is a wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information. -Pranav Mistry
Using SixthSense, one can interact with real world using simple devices and do many amazing things like real-time quality check of products, take a picture and manage the files using only hand gestures with any screen. With SixthSense, every surface becomes a screen!

Technology

SixthSense is composed of:
  1. A camera
  2. A projector
  3. A mirror
  4. Colored caps
  5. Mobile phone
  6. A genius mind to combine these things
This beautiful mind is of Pranav Mistry, a student at MIT who is the person behind the SixthSense technology. SixthSense is associated with technologies like gesture recognition, image capturing, image processing and manipulation. And costs only $350!!!

Working

SixthSense uses the camera and the mirror to record gestures with the help of four colored caps. The user has to wear these colored caps on tips of his/her fingers to help the camera record the gestures more efficiently. The projector simple does its work by projecting the images on any surface, it may be a table, a wall or even a hand. Everything becomes a screen with this pocket projector. The user has to hang the camera and projector in his neck. All these components are interconnected using a mobile phone device, where the real magic happens! The camera captures the user's hand gestures and the colored caps. The software in mobile phone recognizes these gestures along with the distance and relative motion of colored caps to understand the command, performs the desired work and then the projector shows the result on the surface. All this happens in the blink of an eye but it took him eight long months to build this.

What It Can Accomplish

SixthSense has countless application and it is one of the crucial breakthroughs in the history of tech. Using mobile phone's internet access, SixthSense is capable of giving its user useful information about the object its camera detects. It can take a picture using hand gestures and can edit those pictures. It can help us make decisions like which dress to buy by using its intelligent feature of quality check which is supported by the internet. It can help book reading. Similarly, it can enable real-time news reading, a person can remain updated all the time by watching news right on his palm! SixthSense is also loaded with a bunch of smart gestures which are a specific command/input to the software. It's drawing panel can revolutionize augmented reality and artificial intelligence.
There is also an online guide available if you are interested in making it yourself. The instructure for making your own prototype can be found here.

Appreciation

Pranav Mistry
Pranav Mistry is an MIT student and a technology innovator. His marvelous invention, SixthSense, has become an internet sensation. He has received many awards and adulation as a recognition to his efforts and his genius. His fabulous invention helped him win Popular Science Invention Award and Innovator Under 35 Award.
