What impact does filament type have on flexibility in FDM printing?

The correct response highlights the significant role that filament type plays in determining the flexibility of printed objects in FDM (Fused Deposition Modelling) printing. Different materials used as filaments have distinct physical properties, including varying levels of flexibility, rigidity, and strength.

For example, filaments made from TPU (Thermoplastic Polyurethane) are known for their excellent flexibility and are often used to create parts that require bending or stretching. In contrast, PLA (Polylactic Acid) and ABS (Acrylonitrile Butadiene Styrene) tend to be more rigid and less flexible. This variation means that when selecting a filament type, the intended application and required material properties should be carefully considered.

In essence, the flexibility of a 3D printed object is not just a function of the printing process itself, such as print speed, but is primarily influenced by the material chosen for the filament. This understanding allows designers and engineers to create parts with specific functionalities tailored to their intended use.
