3D Printer History
•
3D printing concept as early as a few decades ago has been proposed. In the 1970s, with the
rise of 3D aided design, designers can see virtual 3D objects in computer software, but to these
objects in clay, wood, or is made out of metal model is very difficult, can use time-consuming
cost money to describe. 3D printing, so that the plane into a three-dimensional process a lot
simpler, designer of any changes can be in after a few hours or overnight to re print it out,
rather than spend a few weeks time factory put the new model manufactured. Only in this way
can greatly shorten the production cycle, reduce the production cost. And with the continuous
progress of science and technology, more materials are printed out, it was discovered that the
original can also be so play.

The Economist magazine had commented: "inventions can bring influence, at that age are
difficult to predict, 1750 steam engine so, 1450 printing so, transistors in 1950, too. Now, we
still can not predict, 3D printing will be in a long time how to change the world."

What is the 3D printer
•
3D printer, a machine which is a kind of rapid prototyping technology, it is a kind
of digital model file, the use of powdered metal or plastic and other materials can
be bonded by layer by layer to construct the object technology. In the past, it
was used in mold manufacturing, industrial design and other fields. It is now
being used in direct manufacturing of some products, which means that this
technology is becoming popular.
