Lego is a line of construction toys manufactured by the Lego Group, Lego bricks can be assembled and connected in many ways, to construct such objects as vehicles, buildings, and even working robots. Anything constructed can then be taken apart again, and the pieces used to make other objects. The toys were originally designed in the 1940s in Europe and have achieved an international appeal, with an extensive subculture that supports Lego movies, games, video games, competitions, and four Lego themed amusement parks.
One might wonder how something so great is done well this how since 1963; Lego pieces have been manufactured from a strong, resilient plastic known as acrylonitrile butadiene styrene (ABS). As of September 2008, the engineers use the NX CAD/CAM/CAE PLM software suite to model the elements. The software allows the parts to be optimized by way of mold flow and stress analysis. Prototype molds are sometimes built before the design is committed to mass production. The ABS plastic is heated to 232 °C (450 °F) until at a dough-like consistency. It is then injected into the molds at pressures between 25 and 150 tons, and takes approximately 15 seconds to cool. The molds are permitted a tolerance of up to two thousandths of a millimeter (2×10-6 m), to ensure the bricks remain connected
Mario Lego pieces are not just any other toys - these Lego figure have been modified by adding paint, decals, stickers, parts, or accessories in combination w/ lego parts. - This Lego figure can be lightly played with or displayed, and will come assemble in a baggy, suggested for children 5 yrs old and up. Since it began producing plastic bricks, the Lego Group has released thousands of sets themed around a variety of topics, like the new "Atlantis". Other Examples include town and city, space, robots, pirates, Lego Trains, Racers, Vikings, castles, Bionicle, dinosaurs, holiday locations, scuba diving and undersea exploration, the Wild West, the Arctic, airports and miners.
