What is a primary disadvantage of Rapid Prototyping?

A primary disadvantage of Rapid Prototyping is that it can suffer from a lack of accuracy in the prototypes produced. Rapid Prototyping typically utilizes various technologies, such as 3D printing or additive manufacturing, which may not always achieve the precision required for certain applications. The resolution of the prototype can be limited by the chosen technology, leading to geometrical inaccuracies and surface finish issues. This can be particularly problematic when a prototype needs to fit with existing products or require stringent specifications.

Other options like rapid production time, inexpensive materials, and minimal labor requirements are actually advantages often associated with Rapid Prototyping, as these factors contribute to the efficiency and cost-effectiveness of the prototyping process. However, the trade-off for these conveniences can manifest in compromised accuracy, which is why it is identified as a significant disadvantage in this context.
