L'invention de l'application, 3D Printer.

The invention of the printer 3d is not a completely recent phenomenon. Indeed, this process was invented at the end of the 80s by Charles Hull. At that time, the printer 3d is only a prototype used that in rare companies to test their design before deciding on the production of the mass rooms.

Two big types of processes are used in fact to train (form) objects. Let be the worked material (subject) can enter fusion and can be melted little by little to obtain the desired shape. Let be the material (subject) can be solidified under the effect of the heat or of the light.

It is that from 2000s which we begin to speak more and more printers 3d and is then made of numerous sales.

This new invention is revolutionary and brings numerous advantages in various domains such as the medicine, automobile and the same the military field.

Indeed, in the medical fields, the printer 3d allow to prepare better an operation, to save time and of the precision for a better result for the patient. We can also make a model of organ or fabric (tissue) by means of various types (chaps) of plastics (plastic arts) and even use various colors to differentiate better differents parts as for example damaged bones, blood vessels...

That's not all, for example the scientists and the engineers have create a prosthesis allowing the enlargement of the bladder of a patient. That prothesis can fits the shape of the patient's body. In 2002, a functional kidney is create, capable of filtering the blood. It was testing in first on animals and open the way to the creation of organs and fabrics(tissues) in medical purposes.

(voiture) In 2011 during a conference in Canada, the body of a car which is completely consists of printed pieces was presented. Her production required 44 hours.

(arme) And in the last picture we have all the pieces of a firearm, once again, made entirely thanks to the 3D printer

But the biggest drawback of the 3D printer is her price. Indeed, the 3D printing of lower quality has a price of £ 480. For a better quality, the prices can go up to several thousand pounds.

To conclude, the printer 3d is a revolutionary invention which is

not going to delay spreading more and more in all the domains returning the life easier to numerous people and companies .
