Q.
Which of the following are problems with the current rapid prototyping and additive manufacturing technologies?
Answer & Explanation
One of the key challenges in current rapid prototyping and additive manufacturing is the limited variety of materials that can be used. While the range of materials is growing, many technologies are still restricted to a small set of materials like certain plastics and metals. This limits the scope of applications, especially for industries that require specific material properties, such as high strength or temperature resistance. Overcoming this limitation is crucial for advancing additive manufacturing and enabling broader usage across industries.
Thus correct option is: A.
