TECHNOLOGY INSIDER: How Does 3D Printing Work?

In the past few years we’ve heard much about “3D printing” and the many uses of this emerging technology. But how does 3D printing work? How is it different from other manufacturing processes? In this post, I'm trying to explain these things. Don't forget to add your points via comment section.

ADDITIVE vs SUBTRACTIVE MANUFACTURING:

Making things usually involves a subtractive process: you start with a block of material — aluminium for instance — which you then machine (that is, remove material) until you get the shape and size you’re after.

But 3D printing, or additive manufacturing, does the process in reverse. Instead of removing material, the “printer” dispenses it. The technology gradually deposits the material via a controlled nozzle, layer by layer, building up to a fully formed product. The material used can either be plastic (usually ABS ), or a metal. The process is typically based on a computer-designed model of the object or machine part in question, and can produce relatively complex shapes.

Steps of 3D printing are shown in the picture below.

Robot writes Torah at Berlin's Jewish Museum

BERLIN (AP) — The robot's quill runs across the paper scroll, from right to left, scribbling down ancient Hebrew letters with black ink. It is penning down the Torah, the Jews' holy scripture, and it is doing it much faster than a rabbi could because it doesn't need to take breaks.

The Torah-writing robot was developed by the German artists' group robotlab and was presented for the first time Thursday at Berlin's Jewish Museum. While it takes the machine about three months to complete the 80-meter (260-foot) -long scroll, a rabbi or a sofer — a Jewish scribe — needs nearly a year. But unlike the rabbi's work, the robot's Torah can't be used in a synagogue.

"In order for the Torah to be holy, it has to be written with a goose feather on parchment, the process has to be filled with meaning and I'm saying prayers while I'm writing it," said Rabbi Reuven Yaacobov. The Berlin rabbi curiously eyed the orange-painted robot as it ceaselessly wrote down the first book of Moses. Yaacobov then showed visitors the traditional way of writing the Torah the way it's been done for thousands of years.

Matthias Gommel from robotlab said the robot initially wrote down the Christian Bible in German, Spanish and Portuguese before it was reprogrammed with the help of an Israeli graphic designer.

Both the robot and the rabbi are part of the exhibition "The Creation of the World" about the significance of Hebrew handwritings in Judaism. The show also presents Hebrew scrolls, wedding contracts and other medieval documents from the Braginsky Collection. The robot will be on show through January 2015 — the rabbi and the scrolls will only be there until Aug. 3.

LATEST MECHANICAL NEWS: Germany sets record for peak energy use – 50 percent comes from solar.

The Fraunhofer ISE research institute has announced that Germany set a record high for solar use on June 9—on that day the country's solar power output rose to 23.1 GW—50.6 percent of all electricity demand. The record occurred over a holiday, which meant less demand, but it still marks a major step forward for the world's solar power leader.

Despite not having a generally sunny climate, Germany has been pushing solar energy —but not from the huge solar farms seen in other countries. In Germany, the focus has been on rooftop solar collectors mounted on homes, businesses and buildings of any other kind. Currently, over 90 percent of mounted solar panels in the country are on rooftops. The country broke two other records around the same time, producing 24.24 GW of solar generated power between 1 and 2pm on June 6, and over that entire week, the country produced 1.26 TWh of electricity from solar power. In stark contrast, recent reports indicate that solar power makes up just 0.2 percent of total energy production in the U.S.

The popularity of solar panels on rooftops has been bolstered by generous solar subsidies from the government along with a successful ad campaign. The movement is part of a plan by the German government to reduce greenhouse emissions due to electricity being produced in coal fired power plants and a simultaneous phasing out of nuclear power plants (all such plants are scheduled for closure by 2022). That leaves solar, wind and biomass—the country has been eagerly pursuing all of them, though clearly solar has become the national leader.

LATEST MECHANICAL ENGINEERING NEWS FROM 3D PRINTING TECHNOLOGY (May 18, 2014)

Chinese company prints parts for ten houses and builds them all in one day.

Details-- It's a house in a hurry.

A Chinese company harnessed 3D-printing technology to build 10 one-story houses in a day — a cheaper, faster and safer alternative to more traditional construction.

WinSun Decoration Design Engineering built the houses in Shanghai using four giant 3D printers, which are each 10 meters (33 feet) wide and 6.6 meters (22 feet) high, according to Chinese news agency Xinhua . They produce a mix of cement and construction waste to construct the walls layer by layer, a process much like how a baker might ice a cake.

"We purchased parts for the printer overseas, and assembled the machine in a factory in Suzhou," WinSun CEO Ma Yihe told the International Business Times. "Such a new type of 3D-printed structure is environment-friendly and cost-effective."

Each approximately 2,100 square-foot building costs less than $5,000 to construct. The houses' components are checked for quality as they are being erected because there are no building codes yet for 3D-printing construction in China. WinSun uses a special quick-dry cement to speed up the process.

In addition to decreased construction time, this process also means that construction workers are less likely to be exposed to hazardous materials or work environments. Plus, it's eco-friendly.

"To obtain natural stone, we have to employ miners, dig up blocks of stone and saw them into pieces," Ma told Xinhua. "This badly damages the environment." The houses WinSun built are fairly simple, but Ma added that he hopes the company's 3D-printing technology will one day be used to build skyscrapers.

Liberty Launches Electric Van "DELIVER" that looks like a discarded sci-fi prop

This funky-looking electric van prototype is built as a new generation of urban delivery vehicles developed by the DELIVER consortium, first shown to the public recently in Masstricht, Netherlands. It is the product of a European design process, which focuses on reducing the environmental impact of light commercial vehicles in urban areas. The acronym stands for Design of Electric Light Vans for Environment-Impact Reduction , and was funded in part by the European Union, and a group of auto and parts makers including Fiat. Volkswagen and Michelin as well as many universities and several European cities.

At present, no production plans for the van have been announced, though there’s nothing really standing between the DELIVER van and actual production. It features a Michelin electric motor, rated at 57 kW, in each rear wheel hub, and there is also a two speed gear case in each rear hub. The prototype has 18% more load carrying capacity than a conventional van of similar wheelbase, thanks to its electric drivetrain, and features a range of 62 miles, with a top speed of more than 60 mph. But the DELIVER is not just about reducing pollution in European cities. It has a clever driver’s compartment designed to increase driver efficiency and reduce fatigue.

The B-pillar is omitted on the curb side of the vehicle, allowing the installation of a step out door for the driver.
This makes it easier to get in and out of the van, reducing delivery times, and because the main entrance faces the curb, the driver is never faced with the perils of oncoming traffic.
The DELIVER van may have a face that only a mother could love, but its emphasis on compact size, greater load carrying capacity, high efficiency, and low environmental impact make it a strong candidate for the delivery van of the future in the Old World.

Dutch company launches new-generation urban wind turbines

Could a new generation of wind turbines on residential rooftops be on the way? Saying no might be easy when imagining blade noise, if nothing else. The idea of wind turbines for generating energy in households may draw several arguments against the idea. One may argue the yield from current-generation turbines would be too low, along with having to put up with the noisy blades. A group based in Rotterdam which describes itself as an "R&D" company "built on the re-invented formulas, drawings and principles of Archimedes" is out to change minds. On Tuesday, the company, also called The Archimedes, unveiled its Liam F1 Urban Wind Turbine. The Liam, according to the company, ushers in a "totally new generation of wind turbines for domestic use."

The company said that the turbine easily fits on the roof of a house just as would solar panels. The Liam F1 generates an average of 1,500 kilowatt-hour of energy at a wind-speed of 5m/s, which resembles half of the power consumption of a common household. In combination with solar-panels on the roof, a household could be totally self-supporting for its own energy needs. The Archimedes CEO Richard Ruijtenbeek said, "when there is wind you use the energy produced by the wind turbine; when the sun is shining you use the solar cells to produce the energy."

Because of its design, the Liam addresses limitations of efficiency and noise. The inventor, Marinus Mieremet, company CTO, created a type of turbine that is virtually soundless. The Liam is based on "the laws of nature and the theoretics of the Greek mathematician Archimedes." The form of the Liam is a Nautilus shell. The Liam automatically like a pennant goes for the optimal position of the wind, pointing into the wind for maximum yield.

According to Mieremet the yield is 80 percent of the maximum that is theoretically feasible.

Iran students gear up solar car for US challenge

Clouds may still linger over relations between Washington and Tehran, but that's not stopping a group of Iranian students and their teachers from gearing up for a summer road trip through the American heartland.

Fueled by the sun and their hopes to shine in a first for the Islamic Republic, the 19-strong team is preparing to bring an Iranian solar car to compete in the United States for the first time, in the American Solar Challenge in July.

The flat, rectangular Havin-2, or Brilliant Sun, drove for tests alongside slightly larger gas-powered motor vehicles last week on a stretch of highway in Iran's mountainous north, ahead of the eight-day, 1,700-mile (2,700-kilometer) race that will take it from Austin, Texas to Minneapolis, Minnesota.

While the engine and photovoltaic panels are imported, the team designed and developed a Maximum Power Point Tracking (MPPT) system for the car, which interconnects inverters, battery chargers and other devices to optimize its photovoltaic cells .

Farkhondeh Naziri, 20, in charge of electronics on the project and the only female member of the team from Qazvin Azad University, said they plan to optimize the car's absorption of solar energy based on the route it plans to take. "We first do a simulation of the actual race course and study the weather conditions there. Then we try to calculate what the sun's angles would be during the eight-days," she said.

The 220-kilogram (485-pound) vehicle is 4.5 meters (15 feet) long, 1.8 meters (6 feet) wide and 1.1 meters (4 feet) tall, with a cockpit-like canopy for the driver. With photovoltaic cells covering some 6 square meters (65 square feet) of its surface, the car's lithium-Ion batteries can drive it up to four hours between 90 to 150 kph (56 to 93 mph).

The car's predecessor, the Havin-1, ranked 17th in the 2011 World Solar Challenge in Australia. The team is sponsored by an Iranian bank and a car battery producer, which paid some $150,000 to build the car. Attendance in the event, including travel, is expected to cost the same amount.

World's first electric aircraft E-Fan takes flight

Wellington: World's first ever electric aircraft has successfully taken its maiden voyage. This electric aircraft called the 'E-Fan' is the latest creation of Toulouse-based Airbus. The fact that its engines are powered by electricity, provides it a low-noise, eco-friendly profile. This successful voyage carves a new path for the technology's potential in aircrafts.

The cost amounts to 16 dollars per hour to power providing decent height of 220km/h with a cruising speed of 160km/h on its 30kW engines. The plane can stay in air for around 45-60 minutes if it gets its proper power from 120 250V Li-ion batteries, which are stored in the wings, and backup battery are also provided that lasts around 15 minutes.

Spokesperson at Airbus said that extensive research and stress testing has established that the E-Fan's battery system provides sufficient safety margins and close supervision of all battery cell parameters are performed during test flights.

In the course of its development, Airbus is also confident that it can not only save on costs, but can actually reduce carbon emissions for all new aircraft by 75 percent.
