What is a common disadvantage of 2D cutters?

The correct choice highlights that a common disadvantage of 2D cutters is their high electricity consumption. Many 2D cutting machines, especially those that utilize lasers or other energy-intensive technologies, require a significant amount of power to operate. This can lead to increased operational costs and may necessitate a more robust electrical supply. High energy consumption can also have environmental implications, making the use of such machines less sustainable compared to other options that are more energy-efficient.

The other options, although they may have merits in certain contexts, do not capture the primary disadvantage associated with 2D cutters. For instance, their capacity to operate at high speeds is typically seen as an advantage rather than a drawback, and being able to handle a variety of materials is a beneficial feature that enhances their versatility. Additionally, low cost is often a desirable quality rather than a negative aspect. Thus, the focus on electricity consumption provides a more accurate representation of a potential drawback when evaluating the use of 2D cutters in various applications.
