What are the disadvantages associated with using support structures?

When discussing the disadvantages of using support structures in 3D printing, the addition of support indeed leads to extra post-processing work and an increase in material costs. Support structures are often necessary for printing overhangs or complex geometries that cannot be printed in mid-air. After the print is completed, these supports must be carefully removed, which requires time and effort in the post-processing phase. Additionally, the materials used for supports, whether the same as the model material or special soluble materials, contribute to an increase in overall printing costs as well.

While some of the other options touch on related issues, they may not be as universally applicable compared to the direct implications of added time and expense involved with support structures. For instance, printer speed can be affected indirectly depending on the design and settings but isn’t a primary concern linked directly to supports. Similarly, energy consumption and dimensional accuracy can be factors in a greater context but are not as closely tied to the fundamental issues presented by the use of support structures as the need for additional work and expense.
