Project DescriptionThe 3D printer is quickly beginning to revolutionize the way people can become their own engineers. 3D printing is a quick and convenient way to create prototypes and models, as well as make replacement parts and new creations from ABS plastic. The UP Plus 2, manufactured by 3D Printing Systems, is the new and improved version of the previous model, the UP Plus. Manufactured in 2013, it was to be completely redesigned and made faster, more accurate and easier for the consumer to use compared to the original. The 3D printer is an example of combining mechanical and electrical engineering, which are my disciplines of interest. I've used a 3D printer a lot and I find that it's so useful for making little things that you can't just go out and buy. I worked on modeling projects for school and designed custom items for the home. This could be the future: creating objects and having pieces available to you in your home or office. Models can be drawn with most 3D modeling software, and some programs, like Google SketchUp, are free and easy to use. This makes the Up Plus 2 easy to use for the consumer and makes modeling and design more convenient with accurate results. Role of a Typical Engineer An engineer is someone who creates and designs things to make a more sustainable and practical alternative to something already existing, or to create something completely new to meet a need. An engineer takes a problem and imagines, designs and builds a solution. Engineers have shaped our modern lifestyles and are, in essence, changing the world.Essential Disciplines of EngineeringMechanical EngineeringMechanical engineering is the discipline that interests me most personally...... middle of paper ......we already have. There are no limits to what can be created. Even large-scale models can be broken down into smaller pieces and glued together. One example is a meter-tall model of the Eiffel Tower made solely from parts printed with the UP Plus 2. Potentially, this could be the start of a change in the world when it comes to this little bulb that comes to mind. All over the world, children do not have access to clean water. What if someone had a revolutionary idea and another way to filter water? With a 3D printer, they could create a design and if it was small enough to fit only a few parts per item, the printer could be used to print many parts at the same time and use the new creation to give shape. clean water for these children. Imagine the possibilities of the printer and how it could change the way people live.
