TPU filament is a great choice in 3D printing material for mechanical parts and 3D models that must be flexible, durable, and impact resistant. This filament is commonly used to create wearables, smartphone cases, and prosthetics. However, it can be tricky when you want to print with TPU filament, but have no idea which printer to use, or how to set up your printer accordingly.
In this article, we talk about the technical elements of printing with TPU filament. We will cover the basics and what you should aim for before attempting to print with this material.
3D Printer Setup Tips
- Matching Extruder Type: When using TPU filament, you want to use a printer that has an extruder type that can print with this specific material. Direct drive extruders are recommended, as they deliver a more controlled print with TPU filament being used.
- Accommodating Nozzle Size and Temperature: The nozzle size of your printer’s extruder should be a recommended size of 0,4 mm. However, you can adjust the size to meet the requirements of different TPU filament types as well. The nozzle should also be able to reach a temperature of between 210 °C and 250 °C.
- Print Bed: It is recommended to use a heated print bed when printing with TPU filament. The bed temperature should be between 40 °C and 60 °C. This helps with the adhesion of the build and can make a noticeable difference for your prints.
- Enclosed Print Volume: TPU filament can be affected by temperature fluctuations. Therefore, you want to use a printer that has an enclosed print volume. This will allow for a more controlled print environment as well.
- Printer Speeds: Printer speeds can play a crucial part in accuracy and smoothness. When using TPU filament, you want your printer speed to be between 15 mm/s and 20 mm/s. This will ensure that the extruder can accurately build the model with additive layers.
- Additional Settings: Refraction settings should be adjusted or disabled, based on the specific type of TPU filament that you are using. You should also adjust layer height accordingly. Finally, ensure that your infill settings match the desired density and rigidity of the print.
