Brief History of 3D
Printing- (notes taken from the book 3D Printing-The Next Technology Gold Rush)
3D printers are bringing about a
revolution in manufacturing. Much like the industrial and computer revolutions,
these amazing new machines will completely transform the face of manufacturing,
distribution and consumption.3D printing is not actually a ‘new’ technology. It
is simply now coming into the public consciousness, and being more widely
publicized. 3D Systems co-founder, Chuck Hull, invented stereo-lithography in
1986, and the company remains to this day one of the markets’ largest players,
along with Stratasys and Z Corp. Prices for commercial 3D printers range from
$15,000 to more than $300,000. At the other end of the scale, personal 3D
printers requiring DIY assembly, now sell for as little as $500, whereas five
years ago the lowest-priced printer was at least $15,000. The open source development of 3D printers
began in 2009. Most consumer 3D printers
available at the moment use a manufacturing process in which layers of plastic
are deposited layer by layer, building up to form the required shape of the
final object. This begins with a software process, developed by Stratasys,
which processes an .stl file. . Technically speaking this is known as FDM
extrusion or fused deposition modeling. Some machines work by laying down a
strand of acrylonitrile butadiene styrene(ABS) polymer from a heated nozzle.
ABS is best known as the plastic from
which Lego bricks are made. Other
3D-printer makers have chosen to “go green", using a biodegradable
compound called PLA or polylactic acid, a plastic made from food starch. Some
