3D printing

 3d printing technology is already changing the way we produce objects from tools and toys to clothing and even body parts 3d printing is part of a process known as additive manufacturing where an 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 homes and businesses.

 the first step in 3d printing is to create a blueprint of the object you want to print you can use modeling software like blender to create your own designs or you can visit websites like Thingiverse or Shapeways to find objects other users have 3d modeled once you have a finished design it's time to send it to the printer some printers like the MakerBot replicator 2 have renewable bio plastics pooled in the back of the device almost like a string when the printer receives the data it pulls the material through a tube melts deposits it to the plate where it instantly cools as you can see the 3d object is created through layering where the printer will  add.

 one layer of the object at a time until you have a fully formed structurethe most common material used in printing is plastic but the use of some other materials allow for the creation of some pretty amazing products beyond simple tools and toys 3d printing food is becoming very popular and additive manufacturing has allowed for the creation of some pretty intricate treats in the medical worlds doctors are testing biomaterials for regenerative medicine by using a patient's cells doctors could 3d print small body parts like ears and noses some surgeons have even tested 3d printed organs for transplants recently giant 3d printers.

 in China printed 10 houses in just one day and at a cost of less than $5,000 per house proving just how cost and time efficient 3d printing.
