3D Printing-How it works?
Today, The 3D printing technology is changing the way we produce objects from tools and toys to clothing and even body parts. 3D printing is a part of a process known as additive manufacturing, where the object is created by adding material layer by layer. Additive manufacturing allows designers to create complex parts for machines, airplanes, and cars at a fraction of the cost and time of standard means like forging, molding and sculpting. Now, smaller consumer-friendly 3D printers are bringing additive manufacturing to home and business.
The first step in 3D printing is to create a blueprint of the object that is to be printed. You can use modeling software like Blender to create your own designs. you can also visit websites like Thingiverse and Shapeways to find objects that other users have 3D modeled. Once the design has been finished, it’s time to send it to the printer. Some printers like MakerBot Replicator 2, have removable bioplastic spools in the back of the device, almost like a string. After receiving the data, the printer melts the material that has been pulled from a tube and deposits the material to the plate where it cools instantly. The 3D object is created through layering where printer add one layer of the object at a time until you have a fully formed structure. The most common material used in 3D printing is plastic. But the use of some other materials allows for the creation of some other amazing products other than simple tools and toys.
Nowadays, 3D printing food is also becoming very popular and additive manufacturing has allowed for the creation of some pretty intricate treats.
In the medical world, doctors are testing biomaterials for the regenerative medicine. By using patient’s cells, doctors could 3D print small body parts like ears and nose. Some surgeons have even tested 3D printed organs for transplants.
Recently, giant 3D printers in china printed ten houses in just one day. And cost of one house is $5000 proving just how cost and time efficient 3D printing can be. NASA is sending 3D printer to space. This is going to help astronauts to built and fix stuff in space.
You can buy your own 3D printer for home and create 3d objects of your own design.
