METAL RAPID PROTOTYPING METHODS AND MANUFACTURING TECHNOLOGY PRINCIPLE, APPLICATIONS AND TRENDS
ABSRTACT: The rapid prototyping (RP) is a vital manufacturing process to create a successful product, especially in a competitive global market condition. To be competitive, products need to be cheaper, of high quality and adaptive to customer’s changing needs in short time. Rapid Prototyping (RP) layer-by-layer material deposition started during early 1980s with the enormous growth in Computer Aided Design and Manufacturing (CAD/CAM). Rapid prototyping of parts in metal is becoming a familiar step in the development of new products. The process is now starting to migrate to rapid manufacture where extremely complex shapes can be manufactured in low numbers in a short period of time with no tooling costs. Traditional RP techniques are mainly used in product invention process, such as three–dimensional printing (3-DP), Laminated object manufacturing (LOM),Direct metal laser sintering(DMLS), Selective laser sintering(SLS), Electron beam melting(EBM), Ultrasonic consolidation and

Industry has expressed very strong interest to further develop current prototyping techniques or create new ones that are capable of directly producing metallic or ceramic parts. The evolution from polymers to metals and ceramics is just starting to take place. There are many more difficulties associated with producing a structurally sound, dimensionally accurate metallic part rather than simply a real three-dimensional model for visualization purposes. But if achieved, metallic parts will offer several advantages over plastic parts such as high strength, greater impact resistance and toughness and greater durability. In addition, in situ testing of the formed prototype will be possible under practical working
Manufacturing – within a business the manufacturing department works alongside several other departments such as marketing and purchasing to make sure that they manufacture products efficiently. Manufacturing is generally a long process as detailed designs of products have to be assembled before construction can begin. Manufacturing varies can depend on the organisation type large companies are likely to manufacture products themselves, and they tend to do this on a large scale in order to be able to buy resources in bulk in order to save a substantial amount of money. Small businesses tend to design their own products but may not have the ability to manufacture; therefore they usually hire other companies to manufacture for them - this can be quite costly, so they commonly perform manufacturing on a large scale
Essay #1 Throughout my high school career I myself have participated in various Service activities which I believe all have benefited the community. The one service activity that stands out the most for me is when I began two Lego Robotics teams for children in elementary school and mentored the two teams. I was inspired to help tutor these kids and the I myself had the idea of mentoring these Lego teams because I remember how much I enjoyed building Lego robots when I was a kid. so;, I thought that what better than to teach kids about Robotics.
Imagine a world where communication is difficult, there is not a lot of entertainment, and places are hard to get to. This actually was the world in the 1900s-1910s. Technology has come a long way since the early 1900s. Our world has become more advanced and fast paced due to the advances of technology. Over the last 100 years, technology is by far the biggest change in our culture.
A Rube Goldberg machine is a complicated machine built to do a simple task. This type of machine was invented in the early 1940’s by Rube Goldberg. Rube Goldberg machines are made by combining various simple machines. The three simple machines that I will b using are inclined plane(s), lever(s), and when and axle(s). Inclined planes are very commonly used simple machines and consist simply of a flat, sloping surface.
For example, when Miodownik explains how metals were better for making tools compared to wood, bone, and flint, he explains that “they can be hammered into shape: they flow, they are malleable.” [1] Metal has many other physical properties that make them useful for tools as metal can be rehammered back into shape or melted to create into a different tool. Another example is with razors. Miodownik explains the process of blunting razors is due to the structure of metals in how the atoms are arranged in a crystalline shape and in a specific way. Razors blunt because though collisions between the metal blade and hair, the crystals rearrange shape because bonds may weaken or be destroyed between the atoms in the crystal which creates slight dents on the razors edge.
The technology of the 1950s In the 1950s many inventions and technologies were made such as the radio, TV, and more. Radio was widely starting to be used by the public. During the 50s, radio was used to broadcast messages far from the main cities. Radio helped people in remote locations get news and enjoy entertainment.
My group members and I have been creating, the greatest, Rube Goldberg machine in our classroom! Our group and I have been researching about some possible ideas or objects we could use to build our Rube Goldberg machines. We figured out that we would use water bottles, dominoes, parts of a medium sized cardboard box, a marble moving set, marbles, confetti (to put inside the balloon to see when it pops), and tacks. We would put confetti inside the balloon for when the balloon pops, it will almost be like a big celebration! To pop the balloon we would use a few tacks and tape it onto the domino.
Introduction Lego - one of the best-selling construction toys in the world. Producing one project of Lego toys takes years of design and development, tons of plastics about 1000 Injection Molding Machines which work 24 hours, painting machines, packaging lines, over 100 robots, sorting machines and massive global distribution system. It all begins with simple interlocking bricks and rise to global toy empire – Lego. (Geographic, Jan 18, 2012) Background Lego which stands for two Danish words “leg godt” which means “play well” was founded by Ole Kirk Kristiansen carpentry in 1932. After his death company passed to son Kjeld Kirk Kristiansen.
Tangibles Sometimes patients may only have their senses to evaluate cues to quality, which is why this level of quality is crucial to maintain. Tangibles are the most important dimension of quality. It is crucial to ensure that patients have a sanitary, safe, and comforting servicescape in order to provide patient-centered care. For example, Michael Kyung’s scenario deals with the lack of toilet paper. The patient’s family member perceived the hospital to potentially have poor quality because they could not keep the bathroom clean and stocked with toilet paper.

According to the Oxford dictionary, language is the method of human communication, either spoken or written, consisting of the use of words in a structured and conventional way. To me, the design language is the way designers translate their thoughts visually. Like language, the design language also has the process of inheritance and evolution. The importance of designing language It is undeniable that many designers have the same or similar inspiration, for architects and interior designers, they even use the same material.
The 3D Animation production pipeline of the typical animated video or movie is usually divided into three key stages: Pre-Production, Production and Post-Production. Whether it is a big blockbuster movie or a 30-second film, the process is always similar. It starts with the Pre-Production process. Pre-Production
Nowadays, technology devices become plays an important role in our daily lives, especially in adolescents’ categories. While there is a very clear argument for how the technology is effected on us and causing social isolation as we know, but in another way is also the argument that these technologies are helping us to become more social in our society. This is very probably because we have a good and perfect ability to communicate with each other. Despite long distances. We all know that the goal of technology is to make our lives easier and more efficient.
Digital architecture involves the use of computer modelling, programming, simulation and imaging to create both virtual forms and physical structures. The ways in which architecture is formed, created, presented, and marketed is transforming – in relation to the transition to a digital society. Digital architecture allows complex calculations that delimit architects and allow a diverse range of complex forms to be created with great ease using computer algorithms. Architecture created digitally might not involve the use of actual materials (brick, stone, glass, steel, wood).
Process Strategies The process strategies, for such a large manufacturing company, would need to be varied. The production process type would be determined by the product life cycle stage at that time (Thayer 2004).Product life cycles for items such as smartphones and tablets do not generally follow the standard life cycle stages. The maturity stage can be interrupted by discontinuation or irrelevance of a technology, which recommences the cycle (Giachetti & Marchi 2010). Incidentally, during the product life cycle of these items, a cyclic improvement of both process and product is required to stay in contact with market changes.
