This video is a progression of 3D print as done on an FDM printer. The total print time of the sphere was 30 minutes, but the footage has been edited and shortened for the ease of viewing.

3D printing is a form ofadditive manufacturing technology where a three dimensional object is created by laying down successive layers of material.[1] 3D printers are generally faster, more affordable, and easier to use than other additive manufacturing technologies. However, the term 3D printing is increasingly being used to describe all additive manufacturing processes. 3D printers offer product developers the abilityto print parts and assemblies made of several materials with different mechanical and physical properties, often in a single build process. Advanced 3D printing technologies yield models that can serve as product prototypes. 
Since 2003 there has been large growth in the sale of 3D printers. Additionally, the cost of 3D printers has declined.[2] The technology also finds use in the fields ofjewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, and many others.

[edit] Methods
“ | Three-dimensional printing makes it as cheap to create single items as it is to produce thousands and thus undermines economies of scale. It may have as profound an impact on the world as the coming of the factory did....Just as nobody could have predicted the impact of the steam engine in 1750—or the printing press in 1450, or thetransistor in 1950—it is impossible to foresee the long-term impact of 3D printing. But the technology is coming, and it is likely to disrupt every field it touches. | ” |

A large number of competing technologies are available to do 3D printing. Their main differences are found in the way layers are built to create parts. Some methods use meltingor softening material to produce the layers, e.g. selective laser sintering (SLS) and fused deposition modeling (FDM), while others lay liquid materials that are cured with different technologies. In the case of laminated object manufacturing, thin layers are cut to shape and joined together.
Each method has its advantages and drawbacks, and consequently some companies offer a choice betweenpowder and polymer as the material from which the object emerges.[4] Generally, the main considerations are speed, cost of the printed prototype, cost of the 3D printer, choice and cost of materials and colour capabilities.[5]
One method of 3D printing consists of an inkjet printing system. The printer creates the model one layer at a time by spreading a layer of powder (plaster, or resins) and...
