Material Properties
When working with fold line patterns, understanding the material properties is crucial as they dictate how the material will behave under stress and how it will affect the resulting shape and functionality of the pattern.
- Elasticity: Elasticity refers to a material’s ability to return to its original shape after being deformed. In the context of fold line patterns, elastic materials can be folded and unfolded repeatedly without losing their shape, making them suitable for applications requiring flexibility and durability.
- Plasticity: Plasticity describes a material’s ability to undergo permanent deformation without breaking. Fold line patterns utilizing plastic materials can retain their deformed shape even after the stress is removed, allowing for the creation of more intricate and permanent structures.
