What are the configuration types of supports in FDM?

In Fused Deposition Modelling (FDM), understanding support structures is essential for successful 3D printing, particularly for complex geometries. The correct configuration types of supports in FDM include tree, grid, and line supports.

Tree supports are designed to minimize the amount of material used while providing strong support for overhangs, allowing for a more efficient use of support material and easier removal after the print is complete. They resemble the branching structure of a tree, which helps to distribute the load while maintaining stability during printing.

Grid supports feature a lattice-like grid structure that provides uniform support across larger areas of the print. This type offers a good balance between material usage and support effectiveness, being especially useful for prints that have extensive overhangs or intricate detail requiring support.

Line supports, as the name suggests, consist of linear structures that are printed in lines to support specific areas of a model. This configuration is less material-intensive and is effective for prints with minimal overhangs that still require some support.

Overall, having the option to choose among tree, grid, or line supports allows users to optimize their prints based on the model's specific requirements, leading to better print quality and efficiency. Other choices suggest limitations that do not align with the
