3D Printers

"This machine is called the "3D printer". 3D printer is unlike of the common printers. On a 3D printer the object is printed by three dimension. A 3D model is built up layer by layer. Therefore the whole process is called rapid prototyping, or 3D printing. A common process of rapid prototyping is to apply a fine powder (plaster, bioplastic, polyurethane, polyester, epoxy, metal, etc.) in such a 3D inkjet printers. Printer print out the layer of powder on a bed and form a fixed object. The design is defined by a CAD file". It is one of the technologies that have been rising in trend lately as well even though it's still on its's "prototype" stage however back around the 1990's, it was only popular in the engineering, architecture and manufacturing industries . The 3D printer is basically a printer that can print objects in 3D scale. In other words, it could replicate an object inside the machine, building layer upon layer in order to form a real object. The 3D printer can create an object that can be obtained as a powder. The 3D printers have also been used in the medical industry where doctors can create body parts of a certain patient as a mock part to be operated on. 3D printers are also useful ways to reduce assembly costs of manufacturing products and the fact that it could make instant-assembled products and the other factor is that it's good for companies to experiment with ideas for their product without expense time and tooling expense and if certain products are worth the change. This very machine can also challenge the mass production and  manufacturing of today and of course in the future. 3D printers have also created an impact in some aspects of our lives. 

The development of 3D printers have made ordinary people like us to have a more easier life such as getting the things you want just in an instant in your home and 3D printers have also helped the lives of people who live in disability as well because of the fact that the 3D printers can print an exact 3D model of a body part with bio organic material. The development of 3D printers have also impacted on people's lives with food as well. The use of 3D printers have allowed us top manufacture clothes and food therefore making people in poorer conditions get what they need with ease. 3D printers also have an effect on businesses as well. This is because the printers allow businesses to mass produce their products with ease making them a valuable business asset. Printers like these can also help the world from world hunger as these printers can recreate food from the tiniest of DNA and create more healthier food by just extracting the healthy part of the food and mass produce it.  However, there are also negative impacts that can come from the use of 3D printers in a regular basis. This can lead to recklessness of people when it comes to a certain life-changing incidents. This is because people know that there is a way to resolve their problem easier and make them reckless and not conscious of what they are going to do. 3D printers can also be used to benefit the rich countries and exploit poorer countries into more debt. Other countries or businesses might also just use these printers to mass produce weapons for war which is a risky investment. Even though this kind of technology is useful it can also be a source of problems for the world as well.
