WHAT IS 3D PRINTING??
3D printing technology is already changing the way we produce objects, from tools and toys to clothing and even body parts.
00:00:00
3D printing is part of a process known as additive manufacturing, where an object is created by adding material layer by layer.
00:00:07
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.
00:00:15
Now, smaller, consumer-friendly 3D printers are bringing additive manufacturing to homes
00:00:26
and businesses.
00:00:31
The first step in 3D printing is to create a blueprint of the object you want to print.
00:00:32
You can use modeling software like Blender to create your own designs, or you can visit
00:00:38
websites like Thingiverse or Shapeways to find objects other users have 3D modeled.
00:00:42
Once you have a finished design, it's time to send it to the printer.
00:00:48
Some printers, like the MakerBot Replicator 2, have renewable bioplastic spooled in the
00:00:51
back of the device, almost like a string.
00:00:56
When the printer receives the data, it pulls the material through a tube, melts it, and
00:00:59
deposits it to the plate, where it instantly cools.
00:01:04
As you can see, the 3D object is created through layering, where the printer will add one layer
00:01:12
of the object at a time until you have a fully formed structure.
00:01:17
The most common material used in 3D printing is plastic, but the use of some other materials
00:01:23
allow for the creation of some pretty amazing products beyond simple tools and toys.
00:01:29
3D printing food is becoming very popular, and additive manufacturing has allowed for
00:01:34
the creation of some pretty intricate treats.
00:01:39
In the medical world, doctors are testing biomaterials for regenerative medicine.
00:01:42
By using a patient's cells, doctors could 3D print small body parts like ears and noses.
00:01:47
Some surgeons have even tested 3D printed organs for transplants.
00:01:53
Recently, giant 3D printers in China printed 10 houses in just one day and at a cost of
00:01:59
less than $5,000 per house, proving just how cost and time efficient 3D printing can be.
