"HOW 3D PRINTING IS SHAPING TOMORROW'S ENGINEER"

Abstract

New technologies such as 3D printing enable customized products and solutions (like your Isla!) to be built completely from your product designs as created through computer programs. In contrast to traditional methods of manufacturing (e.g., cutting, shaping, processing/manipulating materials to create something new from a previously made object), 3D printing is an additive process, making it possible to build objects from the ground up creating a much more exact and flexible design than traditional methods, and usually using much less time to produce the finished product than with traditional processes. The impact of 3D printing will extend to many different types of industries including automotive, medical, construction, aerospace, education, etc.

The use of 3D printing technology has become a crucial element in Engineering education as both an instructional tool and a way to connect theory and application of Engineering concepts. With the ability to create their Computer Aided Design (CAD) works into physical 3-dimensional (3D) objects, Engineering students can gain tactile experience with complex shapes, structures, and concepts. Additionally, the use of 3D printing technology permits students to gain experiential learning with regards to their design capabilities in the areas of CAD developing and material choices after using 3D Printing technology, as well as mechanical testing. Engineers-of-short develop critical thinking skills through prototype development and mechanical testing, increasing their ability to creatively apply their theoretical knowledge. Use of 3D printing technology allows for collaboration between Engineers of differing disciplines including mechanical, electrical, civil and computer Engineers, thereby fostering teamwork and creativity across the breadth of the project.

Aside from education, there are a number of other applications for how 3D printing can be used. The medical field utilizes 3D printing for a variety of products such as prosthetics, dental implants, and surgical preparation models. 3D printing also plays an important role in aerospace and automotive industries, as items made from lightweight materials tend to be more fuel efficient and less expensive than heavier counterparts created using traditional methods, due, in part, to the ability to create 3D shapes. The construction and architectural industry is able to showcase their capabilities through 3D printing by producing pre-fabricated models and complex architectural features. Artists and designers can create custom-made products through the use of 3D printing technology that would otherwise be difficult or impossible to achieve through traditional means.

One of the main benefits of 3D printing is its efficiency and sustainable nature due to the addition of materials being only done directly where it is necessary, and this leads to the creation of far less waste than traditional subtractive manufacturing processes. Furthermore, the use of localised, one-off productions of certain items reduces both mass-produced items (which need to be remotely manufactured, hence subject to large-scale transport) and therefore, the amount of energy consumed, and the associated environmental impact. The technology also enables rapid prototyping, which is defined as the quick iteration of designs and the testing of functional prototypes and is helpful in both academic institutions and industrial settings.
