Elasticity and Flexibility: Flexible TPU is known for its superior elasticity and flexibility. It can be stretched and bent repeatedly without permanently deforming, making it ideal for applications requiring parts with high resilience.

Fatigue Resistance: TPU exhibits excellent fatigue resistance, meaning it can withstand repeated cycles of stress and strain without breaking down. This makes it suitable for parts subjected to constant movement or repetitive loading.

Durable and Tough: Flexible TPU is generally more durable and tougher than PLA. It can withstand impact and handling better, making it suitable for functional and mechanical parts.

High Wear Resistance: TPU has good wear resistance, making it suitable for applications where parts will experience friction or abrasion, such as seals, gaskets, and parts in contact with moving components.

Chemical Resistance: TPU often has better resistance to chemicals, oils, and solvents compared to PLA, which can expand its range of potential applications.

Higher Temperature Resistance: TPU can typically withstand higher temperatures than PLA before softening, which is important for applications where parts might experience heat.

Better Layer Adhesion: Flexible TPU usually has better layer adhesion than Flexible PLA, which can result in stronger and more reliable prints.

Wide Range of Shore Hardness: TPU materials are available in a wide range of Shore hardness values, allowing for customization of the material's flexibility and hardness to suit specific applications.

Applications Requiring Complex Geometries: Due to its excellent flexibility and stretchability, TPU is well-suited for printing complex geometries, intricate designs, and parts with fine details.

Functional Prototyping: TPU is commonly used for functional prototyping of products like gaskets, handles, grips, and other parts that require mechanical properties similar to the final product.

What's Different Between Flexible PLA and Flexible TPU?

Aspect Flexible PLA Flexible TPU
Material Composition Modified polylactic acid (PLA) with additives Thermoplastic elastomer with polyurethane chains
Environmental Impact Relatively more biodegradable Synthetic material, potential biodegradability varies
Performance Characteristics Slightly lower rebound resilience and durability Outstanding elastic recovery, fatigue resistance
Application Fields Moderate flexibility, not extreme fatigue resistance High flexibility, excellent stretching, fatigue resistance
Examples of Applications Light stress parts, decorations, etc. Shoe soles, seals, elastic components, etc.
