Select the correct answer using the code given below:
Answer
1, 2, 3, 4 and 5
1. Preparation of confectionery items — Correct. 3D food printing is used to make chocolates, candies and customized edible designs.
2. Manufacture of bionic ears — Correct. 3D printing has been used in biomedical engineering to create ear structures/bionic ear prototypes.
3. Automotive industry — Correct. It is widely used for rapid prototyping, tooling and even production of some vehicle components.
4. Reconstructive surgeries — Correct. 3D printing helps in patient-specific implants, prosthetics and surgical planning for reconstruction.
5. Data processing technologies — Correct. 3D printing is also applied in electronics/computing research, including fabrication of components used in data-processing devices and related technologies.
Hence, all five are valid applications.
