4. Explain the process additive manufacturing. Examine advantages and limitations of the additive manufacturing process. (250 words)

Difficulty level: Moderate

Reference: Indian Express , Insights on India

Why the question: Indian Space Research Organisation (ISRO) successfully tested a liquid rocket engine made with the help of additive manufacturing technology — commonly known as 3D printing. Key Demand of the question: To write about additive manufacturing or 3D printing, its potential and limitations. Directive word: Examine – When asked to ‘Examine’, we must investigate the topic (content words) in detail, inspect it, investigate it and establish the key facts and issues related to the topic in question. While doing so we should explain why these facts and issues are important and their implications. Structure of the answer: Introduction: Begin by defining additive manufacturing or 3D printing Body: First, write about process of 3D printing in detail – digital 3D model is created, then sliced into layers, generating instructions for the printer. The printer follows these instructions, depositing material layer by layer and solidifying or bonding it. Use flow chart for better presentation. Next, write about the potential applications of 3D printing. Cite examples to substantiate. Next, write about the limitations of 3D printing – complexity and scalability of the process, quality control issues, and high costs. Conclusion: Conclude with a way forward.
