TPU (Thermoplastic Polyurethane) is a versatile 3D printing filament known for its flexibility and strength. It combines the properties
of rubber and plastic, offering high elasticity, excellent abrasion resistance, and durability. TPU prints at a temperature range
of 410°F to 446°F (210°-230°C) and is ideal for creating flexible parts like gaskets, seals, and wearable items. Its resilience and ability
to withstand stress make TPU a popular choice for functional prototypes and end-use parts that require flexibility and robustness.
As stated from the name, TPU is a type of thermoplastic elastomer that combines the properties of rubber with the processability of thermoplastics. Chemically, TPU is composed of linear segmented block copolymers with hard and soft segments. The hard segments are typically made from isocyanates and chain extenders like 1,4-butanediol, while the soft segments are often polyols, such as polyester or polyether. This combination gives TPU its distinctive flexibility, elasticity, and abrasion resistance, making it ideal for producing parts that require durability and flexibility, such as gaskets, seals, and wearable items. TPU is resistant to abrasion, oils, and greases, giving it excellent durability for high-wear applications. TPU is often used for products that need to be both durable and flexible, whereas other filaments are typically used for more rigid and structural parts.
