"3D printing" has applications in which of the following? 1. Preparation of confectionery items 2. Manufacture of bionic ears 3. Automotive industry 4. Reconstructive surgeries 5. Data processing technologies Select the correct answer using the code given below:

1. Statement 1 is correct. 3D printing technology (additive manufacturing) is being used experimentally and increasingly commercially for the preparation of confectionery items, creating complex shapes and designs with edible materials. 2. Statement 2 is correct. The manufacture of bionic ears (customized prosthetic or implantable hearing devices) is an application of 3D printing, allowing for precise creation based on individual anatomical data. 3. Statement 3 is correct. The automotive industry uses 3D printing extensively for prototyping, creating custom tools and jigs, and even manufacturing some end-use parts. 4. Statement 4 is correct. 3D printing is used in reconstructive surgeries to create patient-specific surgical guides, anatomical models for planning, and custom implants (e.g., cranial plates, joint replacements). 5. Statement 5 is correct. While not directly processing data, 3D printing hardware relies heavily on sophisticated software and data processing technologies to translate digital models into physical objects. Furthermore, 3D printing can be used to create custom enclosures or components for data processing hardware. Given the broad phrasing, it can be considered an application area where the technology plays a role, either directly in manufacturing related hardware or indirectly through enabling software. Considering the wide range of applications across various fields, all listed items represent areas where 3D printing has found or is finding applications.
