Question 2 (20 marks) Additive manufacturing (AM) or known as 3D printing alligns well with the rapid growth of technology as stated in Industrial Revolution 4.0 (IR 4.0). AM also coordinates with Sustainable Development Goals (SDG) # 9 (Industry, Innovation and Infrastructure) and #12 (Responsible Consumption and Production). Figure 4 shows the recent breakthrough of additive manufacturing that raised a great debate among the experts in the field. a) As an experienced engineer, elaborate your opinion on this latest breakthrough. Your answer may include the benefits and even doubts from this technology. (10 marks) b) In AM, there are four essential technology elements and system integration for viable AM. Identify all FOUR elements. (4 marks)/nc) Suggest TWO of the four elements you answered in 2b) will be the most challenging to control for AM feasibility in years to come and why. Your answer must also include possible solutions for the element you choose. (6 marks) Figure 4: 3D printed house
