What 3D printing materials are flexible?

Flexible 3D printing materials are typically made of Thermoplastic Elastomers (TPE), which are a blend of hard plastic and rubber. The elasticity of these materials allows them to be easily stretched and flexed. Here are some of the most common types of flexible 3D printing materials:

1. TPU (Thermoplastic Polyurethane): TPU is very flexible, elastic, and soft, making it perfect for vibration-dampening applications. It can handle large shocks and impacts. It’s also great for resisting chemicals such as oil and can withstand low and high temperatures well. TPU is probably the easiest flexible filament to 3D print, making it a favorite among makers and the most used flexible filament.

2. TPC (Thermoplastic Copolyester): TPC is another type of flexible 3D printing material.

3. TPA (Thermoplastic Amide): Also known as PCTPE, TPA filament is a mix of TPE and Nylon, combining Nylon’s durability with TPE’s more flexible nature. PCTPE has good heat resistance and great layer adhesion, leading to solid, flexible 3D-printed parts.

4. Soft PLA (Polylactic Acid): Soft PLA is a type of flexible 3D printing material.

The degree of elasticity in the plastic depends on the type of TPE and the chemical formulation used by the manufacturer.
