Flexible filaments, including TPE (Thermoplastic Elastomer) and TPU (Thermoplastic Polyurethane), are known for their elasticity, allowing them to stretch and flex. These materials can simulate rubber with varying degrees of firmness.

Unique Features: High elasticity and flexibility, allowing for the creation of parts that can bend or stretch.
Ideal Use Case: Perfect for flexible parts such as phone cases, wearable devices, tires, and gaskets.
Additional Components: May require a direct drive extruder to prevent the filament from tangling. A heated bed can improve adhesion, but no enclosure is needed.
