Which of the following is a disadvantage of CAD/CAM?

• A. Easy to display ideas to client
• B. High accuracy
• C. Speeds up the development process
• D. Expensive setup cost

Answer: (D)

The main idea here is that CAD/CAM can be expensive to set up. Investing in this technology means buying powerful software, capable hardware, and often specialised training for staff, plus ongoing maintenance and updates. Those upfront costs can be a barrier, especially for smaller projects or firms, even though the system may save time and improve accuracy later on.

The other points describe benefits: CAD/CAM helps you create and display ideas clearly to clients with 3D models, it usually achieves high accuracy in production, and it speeds up the development process through automation and quick iterations. So while those are advantages, the disadvantage among the options is the expensive setup cost.
