“A NEW GENERATION OF HOPE” There are over 11.4 million amputees worldwide in need of prosthetic limbs. Traditional methods of producing prosthetics limit availability due to cost and durability. While the technology is still very new and not well developed, 3D-printing is the future of prosthetic limbs. 3D-printed prosthetic limbs may be printed with different materials, and provide quick production with a lower cost, which can increase the availability of prosthetic limbs to more amputees. 3D-printing

Acknowledgement The completion of this seminar wouldn't be possible without the participation and help of so many people whose names might not enumerated.

LEGO Group was started in 1932 by Ole Kirk Christiansen, who was a craftsman in Western Denmark. After losing his employment, Christiansen began making wooden toys rather than furniture. After a fire in his factory, he was compelled to reconstruct and chose to begin making smaller than usual adaptations of houses and furniture he had worked on as a craftsman. He changed to plastic in 1947 and by 1949 had assembled more than 200 plastic toys. Christiansen devised the term “LEGO" for a company name;

Once you have a 3D model the next step is to prepare it in order to make it 3D printable. Preparing a 3D model to be 3D printed is called slicing. Slicing is dividing a 3D model into hundreds or thousands of horizontal layers. This is done with software. It can sometimes be done within a 3D modeling software application. Certain 3D printers require a certain slicing tool. Once the 3D modelTo begin 3D printing you first have to make a virtual design of the object that you want to create. The virtual

Introduction: The manufacturer of our juicer is Black & Decker who specializes in power tools, hardware, and home improvement products. Our product is a home improvement device used to make fresh citrus juice. Possible improvements that were voiced by customers was the need for a lock to secure the lid and an easier reverse mechanism when the juicer auto-reverses. Whenever customers poured juice, they would run the risk of the lid flying off. It was easy to use and to make juice. The pulp control

(Engineering Toolbox 2014). Each material acts differently in terms of thermal conductivity, therefore altering how much heat is released into the air surrounding the kettle (Engineering Toolbox 2014). The most common plastic used is Acrylonitrile butadiene styrene (ABS) as it is flame retardant, has a high heat resistance, high impact resistance and has good chemical resistance (Professional Plastics 2014). However, plastic is generally not as long lasting as metal as it is thin and is easier to break

Introduction In 1984, 3D printing, also known as additive manufacturing was introduced to the world. A three-dimensional (3D) printer works just as an inkjet printer, but instead of ink, certains type of material would be deposited layer by layer until the anticipated object is constructed. A decade later, this semi-new technology was used to make parts that could be printed overnight with minuscule imperfections. Then, in the late nineties, 3D printing advanced to printing organs with the patient’s

The idea of Barbie came about when a woman named Ruth Handler was watching her daughter play with dolls. In the 1950’s, girls of all ages only had paper or cardboard dolls to play with and preferred to play with cut outs of teenagers and adult dolls. So, Ruth Handler thought to make The Teenage Fashion Doll for older girls, as a three dimensional doll, called Barbie, named after her daughter Barbara (Heppermann 2010). However, Mrs. Handler met resistance when she went to her husband with the idea

This paper is designed for the reader to understand how chemistry is used in Auto Racing. The first main point to be addressed in this paper is Safety and how chemistry is used in the design of race cars and racing safety gear. The second main point to be addressed in this paper is the engine and how the car works. The third main point addressed in this paper is tires. First, Safety is necessary in everything in life, especially in any form of racing especially when you’re reaching speeds up to 200mph

In order to better understand this lab one must first understand about polymers and their monomer units. Polymers are substances containing a large number of structural units joined by the same type of linkage. The small molecules that make up these polymer chains are called monomers. Polymers in the natural world have been around since the beginning of time and are found many places in nature. Starch, cellulose, and rubber all possess polymeric properties. Cellulose and starch are actually polymers
