3d printing

1. What's 3D printing?

3D printing is also known as desktop fabrication or additive manufacturing, it is a prototyping procedure whereby an real object is made from a 3D layout. The digital 3D-model is saved in STL format and after that sent to a 3D printer. The 3D printer then print the design layer by layer and form an actual item. Read more..

2. 3D printing technologies

Quite a few technologies are able to do 3D printing. The main differences are how layers are built to make parts.

SLS (selective laser sintering), FDM (fused deposition modeling) & SLA (stereolithograhpy) are the most widely used technologies for 3D printing. Selective laser sintering (SLS) and fused deposition modeling (FDM) use melting or softening stuff to make the layers.

This video describe how laser-sintering procedure melt fine powders, bit by bit, into 3D shapes.

This video reveals how FDM works.

The video belows explains the procedure for Stereolithography (SLA).

Typically, the primary factors are speed, cost of the printed image, cost of the 3D printer, pick and price of materials and colour abilities.

3. The real history of 3D printing

October 5, 2011 - Roland DG Corporation introduced the new iModela iM 01.

Sep, 2011 - Vienna University of Technology, a smaller, lighter and more economical printing apparatus has now been created.

This smallest 3D printer weighs 1.5 kilograms, it costs around 1200 Euros.

Aug, 2011 - The world's first 3D printed aircraft created by Engineers at the University 3d printing of Southampton.

4. 3D printing applications

Some of the most crucial programs of 3D printing is in the medical sector. With 3D printing, surgeons can make mockups of parts of the patient's body which must be operated upon.

3D printing ensure it is possible to produce a part from scratch in only hours. It allows designers and developers to go from flat screen to exact component.

Nowadays practically everything from aerospace parts to playthings are receiving assembled with all the help of 3D printers. 3D printing can be utilized for jewelry and art, architecture, fashion design, artwork, architecture and interior design.

Here are some outstanding examples of 3D-printing:

The World's First 3D-Printed Car

World's first chocolate printer

World's first 3D printed bikini

5. What exactly is a 3D printer?

3D printer is unlike of the most popular printers. On a 3D printer the item is printed by three measurement. A 3D model is built up layer by layer. Hence the whole procedure is called rapid prototyping, or 3D printing. Read more..

The resolution of the current printers are some of the the 328 x 328 x 606 DPI (xyz) at 656 x 656 x 800 DPI (xyz) in ultra-HD resolution. The correctness is 0.025 mm - 0.05 millimeters per inch. The model size is up to 737 mm x 1257 mm x 1504 mm.

The biggest drawback for the individual home user continues to be the high cost of 3D printer. Another drawback is the fact that it takes hours as well as days to print a 3D model (with regards to the intricacy and resolution of the model). Furthermore above, the professional 3D applications and 3D model design is also in a high price range.

Instead there are already simplified 3D printers for hobbyist which are substantially more economical. And the stuff it uses is also more affordable. These 3D printers for home use usually are not as exact as commercial 3D printer.

6. Whats the difference between a basic rapid prototyping machine and also a 3D printer?

3D printers will be the simple version of rapid prototyping machines. It's lower lost and less capable.

Rapid prototyping is a conventional method that is used by automotive and aircraft industries for decades.

In general 3D printers are compact and smaller than RP machines. They're well suited to be used in offices. They use less energy and take less space. They are intended for low volume replica of real objects made of nylon or other plastics. If you'd prefer to find out a lot more about this visit markerbot.That also means 3D printers make smaller parts. Rapid prototyping machines have construct chambers at least 10 inches on a side, a 3D printer has less than 8 inches on a side. Yet a 3D printer is really capable of all the functions of rapid prototyping machine such as checking and validating design, creating prototype, distant sharing of advice etc.

Hence 3D printers are easy to manage and economical to keep. You'll be able to buy one of those DIY kit in the marketplace and build up yourself. It is less expensive than the professional rapid prototyping, for $1000 or less you may have one 3D printer. While the professional rapid prototyping cost at least $50,000.

3D printers are much less accurate than rapid prototyping machines. Due to its simplicity the material options may also be limited.

7. What can you make using a 3D printer?

In 3D printing place, people say "If It Is Possible To Draw It, You Can Make It". In the video below shows many items could be produced using a 3D printer. Nevertheless complicated things can only be produced by professional 3D printers, they are not yet affortable for common family.

Is Apple planning a 3D printer?

LONG BEACH, CALIF. -- Communicating here today in regards to the incredible development of the 3D publishing sector, specialist Terry Wohlers slipped one name into a set of probable appliance manufacturers that took some by surprise: Apple.

Wohlers was offering in the SPEEDY 3D Publishing Seminar and Expo. His agency, Wohlers Associates, produced its 2015 document, its last annual, last month.

"I am not suggesting Apple has a product, but will they enter into ecommerce? Probably," Wohlers said. "I mean, Autodesk has gotten into it. Microsoft, Adobe -- the number continues on. Hence the important IT and technology organizations have gotten into this and we consider maybe Apple will also.

"I do believe the iPrint will be a great brand," Wohlers continued. "You heard it here first."

Another technology giant, Hewlett Packard, reported this past year it will be delivering a 3D printer. HP's Multi Jet Combination equipment will have the ability to make manufacturing components for corporations, and not produce the more widespread one off prototypes, HP states.

Industry overall is growing. The additive production sector has quadrupled in sales over the past five decades, reaching $4.1 million last year, of which $2 million originated from unit and product income, Wohlers said. The remainder was from software and solutions.

In 2014, 139,584 desktop 3D printers -- thought as charging significantly less than $5,000 -- were sent, dwarfing how many commercial printers, which observed 12,580 items shipped in 2014.

Of course, when it found revenue, the change was accurate. Industrial 3D printers, that may charge thousands and thousands of bucks each, reached $1.12 billion in income a year ago; desktop 3D printers gained $173.3 million, accordingto Wohlers' statement.

Mainstream companies, such as aerospace and biomedical, are growing their usage of 3D publishing to reduce expenses by simply-intime production and being able to produce brighter elements which can be redesigned onthefly.

For example, Airbus has made out of 45,000 to 60,000 3D-produced areas because of its aircraft and improved its additive manufacturing staff to 35 regular employees in 2014, up from 20 in 2013.

A prosthetic hand-printed on an Ultimaker 3D printer by Refugee Available Ware, a humanitarian invention consortium that is employing 3D publishing to replace the limbs of people injured in battles all over the world. The printer and palm were on display in the SPEEDY 3D Printing Conference in Long Beach this week.

"It Is proven engineering and it hasn't had troubles," Wohlers said. "They're all in like GE and Boeing are. We feel over 100,000 chemical manufactured components are flying on Boeing aircraft today."

Additionally becoming increasingly common are hybrid models, which incorporate CNC tooling, or subtractive manufacturing techniques, with chemical production elements. The models will first 3D-print a level of material, either plastics or metal, plus a running software can further improve it whilst the print job persists.

"We Are viewing a great deal of corporations only in recent years... announce plans or involve some degree of progress going on," Wohlers said. "It Is an appealing time in this company."
