The Beglnnlng of a Revolution Speciflc Purpose: To inform my audience of the process of 3-D printing and the many real-world applications. Thesis: With the advancement of 3-D printing technology these printers can and will change our lives in the manufacturing and medical Industries. Change our lives In the manufacturing and medical Industries. Attention: Imagine a future were you are able to simply download data and print a phone case, shoes, glasses, cars, and even organs. Well you don’t have to imagine this is a reality and is being done today.
Relevance: This technology has been around for 30 years, but is just started filtering into the public arena. We are living in the beginning of a time that people will look back on as a revolution. (Harouni, 2011) Credlblllty: I have Invested $2,000 In the stock market. After doing extensive research over the past couple of years on this technology three quarters of my Investments are in 3D printing technology. Preview: You’re probably thinking right now, how is this technology going to create a revolution? (1) understanding the process of 3-D printing Is Just the beginning.

The pplications for this technology In the (2) manufacturing Industry and (3) medical industry can and are already changing our lives. BODY l. Process of 3-D printing. Traditionally we have made thing from doorknobs to scalpels to engine parts, by cutting, drilling, shaving, or molding a material to create the desired shape. This has all changed due toa process called additive something to print. 1. Explain the software that must be used to create the correct data that a printer can read. (Fleming, 2013) a.
Using computer-aided design (CAD) software, helps when determining the structural integrity you can expect, also elping to choose what material you may want to use. b. How a slicing algorithm uses the CAD model to get detailed information for every layer. (like slicing meat) B. Printing is done one very thin layer at a time building up the object. 1. Additive manufacturing the process of creating something by layering material until the desired shape is achieved. a. Uses technology similar to an ink-Jet printer by using rubber, plastics, polyurethane-like materials, metal, and many more. . Explain how with this technology we are now able to build more precise and intricate objects that were impossible. a. Average layer is about 100 microns or one tenth ofa millimeter. (Fleming, 2013) b. Being able to create a structure within a structure making objects more durable because it is one solid object. [TRANSITION: So now that we’ve talked about the process and capabilities of 3D printing, lets take a look at the applications and effects of this technology in the manufacturing industry. ] II. Manufacturing Industry.
Today you are able to purchase a 3D printer that you can assemble for about $300. With the increased accessibility and efficiency this technology is becoming more economical not only for manufacturers but also consumers. A. Production applications for manufacturers a are vast not only in the production of products, but the process as a whole will change (Harouni, 2011) 1 . With this technology manufactures can lower their carbon footprint. a. Instead of shipping products all over the world, we’re sending data over the Internet. 2.
Industries that rely on a lot of prototyping will benefit especially from this technology a. Digital data storage and delivery is the key to this. b. Being able to have and test the prototype in as short as an hour and be able to tweak the object as needed B. Applications for consumers to interact with this echnology will change how manufactures produce products also. 1 . Being able to produce objects or parts on demand a. Example ofa vacuum breaking down, realizing that it has been discontinued, you can now download and print that part on demand. . Forgot a birthday, Valentines Day or worse an anniversary? No problem, you can make something in a matter of hours that will get you out of the doghouse. 2. This will and is taking customization and personalization to a whole new level. a. Customization traditionally: Nike, smart cars, Prada, & Oakley for example. Now you can shoes that shape your foot, fashion hat is all your own. b. Knowing exactly what you want going into a store and can’t find that perfect decoration or lamp.
Now you can make one that your own personal style and taste. [TRANSITION: Now you have learned about a few of the many application in the manufacturing industry, lets look at the affects and applications in the medical industry. ] Ill. Medical Industry. 3D printing also Bio printing in the medical world could have the has been able to make incredible advancements. A. Instead of ink or plastic doctors are able to use real human or stem cells to create human organs and tissues outside f the body. (Atala, 2011) 1 .
A major health crisis today is the shortage of organs, last 10 years number of patients has doubled, while number of transplants has barely gone up. a. This technology allows doctors to take cells from a person’s body and create a scaffold or structure for cells to grow on. The bodies wont reject it because they are your own cells. b. Example of Luke Massella receiving a bio printed kidney done by Dr. Atala. (Atala, 2011) 2. We are now able to make prosthetics and implants that are personalized to an individuals certain specifications and needs. Diana, 2014) a.
By taking an MRI scan and converting it, prostheses are created from those scans that is very similar to original part. b. You go to the dentist and have a scan done and need implants or dentures. While you are sitting in the chair realizing how much you hate the dentist the implants or dentures are simultaneously being made in that same place.
