TPU (Thermoplastic Polyurethane) is a flexible and durable 3D printing material that is becoming increasingly popular for a wide range of applications. It's an excellent material for producing phone cases, toys, and other flexible objects. However, printing with TPU can be challenging due to its unique properties. In this article, we'll discuss five tips for printing with TPU material to achieve high-quality 3D prints.Use a Bowden ExtruderWhen printing with TPU, it's best to use a Bowden extruder rather than a direct drive extruder. A Bowden extruder has a tube that guides the filament to the hotend, which reduces the pressure on the filament and prevents it from buckling or bending. This helps to prevent jams and other printing issues.Print SlowlyTPU is a flexible material that can easily warp or stretch during printing, so it's essential to print slowly. This allows the material to cool and solidify before the next layer is added, reducing the risk of warping and other issues. The recommended printing speed for TPU is between 20-30mm/s.Use a Cooling FanWhile TPU requires some cooling, it's important to use a fan with a low setting to avoid cooling the material too quickly. This can cause warping and other issues, so it's best to use a fan to cool the material slightly during printing. The fan should be positioned to avoid cooling the build plate directly.Use the Right TemperatureTPU has a narrow temperature range, so it's important to use the right temperature for the material. The recommended extruder temperature for TPU is between 220-240°C, while the recommended bed temperature is between 50-60°C. It's best to start at the lower end of the temperature range and adjust as needed.Check Filament QualityTPU is a sensitive material that can be affected by the quality of the filament. It's essential to check the quality of the filament before printing to ensure that it's free of impurities or moisture. It's also important to store the filament in a dry, cool place to prevent it from absorbing moisture from the air.In conclusion, printing with TPU material can be a rewarding experience, provided you follow these five tips. Use a Bowden extruder, print slowly, use a cooling fan, use the right temperature, and check the filament quality to achieve high-quality 3D prints. By taking these steps, you can produce flexible, durable, and high-quality 3D prints with TPU consistently.
