II. Manufacturing: 3D printing has many advantages over traditional construction methods. With the help of 3D printing, an idea can transform a designer’s computer to actual finished product or component, potentially skipping many of traditional manufacturing steps, which includes procurement of parts, creation of moulds, creation of parts using different moulds, welding metal parts together, machining to carve parts from blocks of material and final assembly. It also reduces the amount of material wasted in manufacturing and creates difficult objects with complex geometric structures like fractals which can add strength, or are natural in shape, may reduce weight, or increase functionality. In a typical metal manufacturing, for example,…show more content…
Let us look into some of the industry it has changed with few interesting examples: 1. Automobiles: Major car manufacturers, such as Ford, Jaguar, GM, Audi and Land Rover have been 3-D printing auto parts for several years now. One example of lot is :Lamborghini’s newest flagship model Aventador which is a two-seat sports car and is Top Gear Car of the Year for 2011. The key to the Aventador’s tremendous performance is its carbon-fiber reinforced composite (CFRC) monocoque, which forms the core of the chassis. The #D printer of Stratasys called Fortus was used to build an envelope that was large enough to produce a 1/6 scale prototype model of the body and chassis at single go in one piece. The Lamborghini Research Lab built complete 1/6 scale model of the body and chassis in just around two months, including the final printing out and assembling of the parts. The build time of the complex inner tub was 6.3 days and material cost was a mere $560. Total build time and processing time included time for sanding ,support removal , painting, etc. Which came out to be 20 days. Total cost including all overhead expense of materials, labor and machine time was $3,000 to create the working prototype. This makes the prototyping much affordable even for new players. Another example of applying 3D printing in this industry is printing not only the prototype but the complete car or at least the body of it. That is how Urbee ("urban electric"), a new
