What is tpu filament?

TPU filament is a type of thermoplastic elastomer filament that is known for its flexibility, durability, and resistance to abrasion. It is commonly used in 3D printing applications that require parts with rubber-like qualities, such as smartphone cases, shoe soles, and medical devices.

TPU filament has a low shrinkage rate and high elasticity, making it ideal for printing objects with intricate designs and complex shapes. It is also resistant to oils, greases, and chemicals, making it a suitable material for industrial and mechanical applications.

TPU filament is available in various diameters and colors and can be printed on most FDM 3D printers that have a heated bed. It typically requires a higher printing temperature than other thermoplastics, such as PLA or ABS, and may have a tendency to string, so proper settings and calibration are essential for successful prints.

Overall, TPU filament is a versatile material that offers a unique combination of flexibility, durability, and resistance, making it a popular choice for a wide range of 3D printing projects.
