  • 3d Printing Case Study

    Introduction/Background -What is the nature of the product or technology? The nature of 3d printing is nearly any area you can think of applying it to. -What is its development history? Rapid prototyping came about in the late 1980s and early 1990s. ‘Rapid prototyping ‘paved the road for all the 3d printing companies out today. (Rapid prototyping created prototypes for a manufacturer to create a prototype of a product with plastics before executing their plans and mass producing them from their required material.) The original advance in 3d printing technology started with MIT(Massachusetts Institute of Technology) and through 3d systems, a huge innovator in the 3d printing world. Charles Hull first created his Stereolithography apparatus(SLA) machine in 1983, and then 3 years later, in 1986, went on to patent his creation, and co-found 3d Systems with that success. On the other hand, Carl Deckard was working on his own RP(Rapid prototype) machine, which he termed Selective Laser Sintering(SLS). -For what may it be used (needs addressed and/or functions performed)? 3d printing, or…

    (CAD). This has to be translated so that the machine can interpret and recreate the data. There are different formats used, but a common one is Standard Tessellation Language (STL). An STL file is created for each layer. There can be several layers per millimeter. The machine then creates a model layer-by-layer using one of several different methods. There are an incredible amount of different processes which can be more easily classified by the nature of material deposition. They fall…

  • The Importance Of Optical Linear Encoder

    Determining the location of our fixture in space may seem like a simple task but if our goal is precision then we need to know exactly where our platform and ball screw are located at all times. To accomplish this goal, we will need to use a combination of encoders and dial gages to keep position and to check our position and precision. Encoder/Glass Scale A linear encoder is the typical way that CNC machines measure motion. It’s electro-mechanical device that creates digital signals that…

  • Biomedical Engineering Personal Statement

    recent years, I was convinced. A further study on bionic eyes mechanism gave me a full comprehension on how electrically stimulating the retina in responding to visual input. Naturally, biomedical engineering is an exacting field, requiring innovation and problem solving skills together with biological science knowledge, which is the perfect blend for me. Curable of disease is not only the focus of biomedical engineer but also the life standards of patients. Meanwhile, from tissue culturing to…

    The first method is called Stereolithography (SLA).[6] This method starts by creating a 3D model on a computer with precise information of each layer. This information is then transferred to a printer. Liquid resin is then exposed to ultra-violet light to create the product layer by layer. After the whole process is finished, the finished product is rinsed in solvent and cleaned. This method is the oldest technique in the 3D printing history. The second method is called Fused Deposition Modeling…

    species foraging strategies), it shows the patterns on the teeth of the species, which it reflects certain food was eaten before the species died. (Ungar et al 2008) Therefore, consumption of hard diets, such as brittle foods tend to have a lot of pit stops, complex microwear surface texture, while those who ate leathery leaves or stems having a long, parallel stripes based multi-plane anisotropy. (Ungar et al 2008) Moreover, CT scan (computed tomography) application provides a convenient…

  • Three Major Manufacturing Process: Subformive, Subditive And Subtractive Processs

    shape, either by using dies or moulds. Examples of formative processes are stamping, forging, drawing, rolling or extruding. Subtractive processes on the other hand remove layers of material to form the final part. Turning, milling, grinding, electro chemical machining (ECM), electric discharge machining (EDM), etc. are all examples of subtractive processes. Additive processes, which is the most recent manufacturing process, produces parts by building the part up in a layer-by-layer manner.…

  • 3-D Printer Essay

    being replaced by custom, innovative replacements. The 3-D printer is an incredibly efficient tool that doctors have begun using to create personalized solutions for problems that the medical field previously had no solutions for. Johnson (2014) is among many who feel that 3-D printing is a disruptive technology that will revolutionize industries such as transplants and prosthetics in the coming decade. The invention of the 3-D printer came in 1984 (Salomon, 2012). Chuck Hull wanted to design a…
