Old Riley Lewis and several of his eighth-grade friends gathered at his house in Santa Clara, California.
About five people, according to the people around them, grab some chips and bean paste, fix the garage, and Riley and his dad create some state stuff in the garage --of-the-
Art manufacturing center.
Boys can make almost anything they can imagine on a machine called RapMan.
Over time, they covered the table with their own work: rockets, guitar picks and cutlery.
They insist on plastic extrusion rates and thermodynamics and how these forces affect the accuracy of objects they can produce.
A boy named Douglas told Riley, \"This is a very beautiful piece of equipment you printed . \".
The kids were obsessed with what versions of the Linux OS they were running on their laptops, and made awkward jokes.
\"I\'ll stab you with a flash drive,\" Riley told Vernon, a boy with a skinny, wearing a pigtail and showing off a pair of freshly made plastic brass knuckles.
Vernon said, \"I want to print an article for one of my teachers and put it on plastic paper, not on paper, just to confuse people. ” lazy-img-

Ashlee Vance, the author presented by MakerBot Riley and his friends, has accepted the mundane fact that the computer design can be passed between friends, modified at will, and then resurrected through the microwave ovensize machines.
RapMan is a rough approximation of the more expensive and complex prototypes used by the company, just as amateur computers are a crude imitation of mainframes.
Riley and his father David spent 32 hours assembling a 3D printer with a $1,500 amateur kit.
Like many 3D printers, Lewis\'s RapMan melts the plastic (

Then spray it out of the movable nozzle in a controlled manner.

When asked to make a cup, the machine will put a plastic ring, reduce the platform by 1mm, and put down another plastic ring until the Cup is finished.

RapMan can do the same.

Automakers and airlines have been using it for 25 years
Design 3D printers for prototype parts for their vehicles.
Recently, the medical field has turned to machines that make custom hearing aids and invisible braces, while architects use this technology to produce models and make prototypes of their latest products by consumer electronics companies.
For all walks of life, 3D printers have become an indispensable tool for doing business.
Prices for large industrial systems range from $5,000 to $1 m.
Now they can print in plastic in different colors and use other materials such as metal, glass and ceramics.
Software manufacturers are using this capability to make better tools for operating objects.
Today, the market for 3D printers is about $1.
Wohlers Associates, a consulting firm that tracks the industry, said 7 billion.
Wohlers predicts that the market will reach $3 as machine sales grow rapidly.

The industry has experienced integration.
In the past few years, the 3D systems company that invented the 3D printing industry has acquired one of its competitors and many hardware, software and design companies.

As industry often happens
3D printing technology has been downstream to consumers.
The 3D system is on the way.

At the heart of it is RapMan, but it is pre-assembled and looks like the brain of an Apple industrial designer.
Now anyone can buy a 3D printer for $1,299 and connect it to Wi-
Fi network and start downloading files that will become real objects.
At the same time, design software manufacturer Autodesk has released 123D, a free set of apps that allow ordinary people to design and customize objects on their computers and even ipad, then send them to machines like cubes.
Consumers have joined these players.

Research Laboratory of the company.
It originated in Southern California about 30 years ago, where Chuck Hull worked for a modest person --
Size manufacturer called UV product or UVP.
Hull, a trained engineer and physicist, helped guide the company\'s development of UV rays
Light curing resin used to add protective coating on furniture and other surfaces.
Hull has always been a repairman and started experimenting in a few hours to lay a lot of resin coating to make a plastic model.
\"I \'ve been an engineer for 20 years and it\'s always very difficult to make prototypes of plastic parts,\" said Hull, 73 . \".
\"You will design a part, go to a tool manufacturer that makes a plastic model, and then you will need to solve any problems and start over.
The whole process took about six weeks, so the idea of using machines to make parts for themselves was pretty cool.
Hull crafted the first rough 3D printer in a back house in the UVP office.
He filled a small basin with liquid resin and placed a platform in the basin controlled by the elevator mechanism.
Hull then installed a removable UV light fixture with a shutter at the top and wrote some software to control the orchestration of all these parts.
The platform will rise near the surface of the resin so that there is only a thin layer of liquid on the top.
The light will be on, the plastic will harden, and then the machine will lower the platform and lay a new layer of resin, and the process can start again.
When Hull showed the machine to the president of UVP, he received frustrating news.
The company\'s main business has deteriorated and Hull and several other workers will be fired.
So he persuaded the president to reach an agreement that Hull would set up a company around new technology and provide a part of the business to UVP.
Hull filed a patent for the craft and dubbed it.
\"I was there, a 40-something-year-

While the process still requires manual operation today, it is rapidly becoming faster, cheaper, and more automated, opening the door to technology for new customers.
Companies like Mercedes, Honda, Boeing and Lockheed Martin have used 3D printers to prototype or make parts that go into the final product.
The technology has been extended to attract vacuum manufacturers Oreck and Invisalign, who produce custom dental braces.
Microsoft also uses a 3D printer to help design a computer mouse and keyboard.
\"A person who buys a BMW will want a part of a car with their name on it, or customize the seat according to the outline of their body,\" said Abe Reichental, CEO of 3D Systems.

Our imagination limits possibilities.
Reichental, 55, came to 3D Systems eight years ago to prepare for the company\'s business.
He has worked for seal air for 22 years and the company\'s sales have grown from $78 million to $4 billion.
Reichental\'s last job at Sealed Air is to manage the department that makes plastic films to cover food and other items.

Comments on print-for-
The 3D system runs out of this facility.
The customer will order the parts and the production manager Lewis uses special software to arrange the parts and plug as many objects as possible into a block.
What is really exciting, however, is that the 3D system has introduced affordable printers for consumers.
He showed an early version of the cube, which is scheduled to be sold in May.
Unlike amateur kits, Cube can be printed at any time.
People who buy this machine will find dozens of 3D print objects pre-installed, meaning they don\'t have to learn the nuances of 3D design software right away to make something.
This machine can print dozens of colors and can be up to 5 by 5 inches in size, which is enough to handle objects such as chess pieces, jewelry and cookie cutters.
The raw material for the cube is the $50 plastic wire shaft, one of which is enough to make about 15 bracelets that can hold the iPod Nano.
It takes 90 minutes to print each bracelet.
You can use software like Autodesk 123D to design your own objects or pay for one of thousands of designs at the 3D system Cubify online store --$4.
Elephant $99, ring $10, razor handle $15.
Cube is facing fierce competition in the consumer market.

Shapeway also has online design software that allows people to personalize things such as napkin rings to add vitality to their next dinner party.
Shapeway prints the object after placing the order-

The unique quality of the 3D printer leads to proximity-
It is impossible to create in any other way.
For example, you can order the ball inside the ball.
\"There are 70 moving parts in other projects, but they are all printed as a whole,\" said shapeway CEO Peter weijinjausen in LA 3D.

The company sells about 100,000 items per month;
The most popular ones are jewelry, iPhone case and train model.
Like the children in the Lewis garage, Wei Jemma shassen has a different view of consumer goods.
Manufacturers have had to worry about the popular appeal of their products since the Industrial Revolution.
If you feel pain in designing a lamp, you want to make sure that thousands of people will order it and make the cost of production worthwhile.
The equation has been overturned.
Designers can sell one or two items at a time because there is no manufacturing cost before actually ordering the item.
As weijinjausen said, \"The basic premise that we are working on is that everyone should be able to make or buy anything they want.
