Which of the following is NOT an advantage of using FDM?

Using Fused Deposition Modelling (FDM) has many advantages, but continuous maintenance is not one of them. The FDM process is designed to be user-friendly and typically requires minimal ongoing maintenance compared to other manufacturing methods. While some upkeep is necessary to ensure optimal machine performance, it is not a constant burden.

The predictability of material shrinkage is a benefit of FDM, as it allows for better dimensional control in prints, significantly improving the quality of the end product. Additionally, FDM is known for its low initial purchase cost, making it an accessible option for many hobbyists and professionals. The process is also regarded as clean and safe, with minimal emissions or waste produced during printing, which appeals to users concerned with environmental impact.

In summary, the choice highlighting continuous maintenance as an advantage misrepresents the reality of FDM, where the focus is more on ease of use and maintenance rather than a ongoing requirement.
