Q1) Additive manufacturing are rapidly changing the landscape of aircraft manufacturing components with its ability to manufacture parts with complex shapes and cavities. FIGURE Q1 shows a lightweight aluminum bracket used in an aircraft to hold down various cabin components together. There are in total 500 pieces of these brackets in one particular aeroplane. The current total weight of the 500 pieces aluminum bracket are 125 kg since each bracket weighs 250 gm. The aluminum bracket are currently fabricated using conventional manufacturing techniques by machining and then welding them together. FIGURE Q1 a. As a product design engineer you are required to redesign the bracket to reduce its weight while fully maintaining its functionality. Idealize and sketch how different would you design the aluminum bracket for manufacturing using additive manufacturing methods to reduce its weight to lower than 250 gm. b. If you are required to quickly produce ONE (1) preliminary non-metal prototype based on the new bracket design you idealize in Q1 part (a) of the new aluminum bracket for form and fit purposes which additive manufacturing system would you select? Evaluate and justify you selection. c. Later if you are required to produce another TEN (10) prototypes you idealize in Q1 part (a) for form, fit and functionality testing which additive manufacturing system would you select? Justify you selection. d. If you are required to use the same additive manufacturing machine for manufacturing both the non-metal prototype in Q1 part (b) and the metal prototype in Q1 part (c) which additive manufacturing system would you choose? Justify you answer. e. What is the best choice of material would you choose for manufacturing the ONE (1) non-metal prototype in Q1(b) and the TEN (10) metal prototypes in Q1(c)? Justify your answer by providing full technical specifications for both materials.
