TPU-LW White Lightweight TPU Filament 1.75mm 750g eSun

Flexible lightweight TPU with individually adjustable density and strength! This innovative TPU filament from eSun is specifically designed to foam during printing. Density and strength can be individually adjusted by printing temperature and extrusion factor. With a maximum foaming ratio of 200%, the weight can be significantly reduced without losing stability. The material has a fine matte texture that minimizes visible layer lines and gives a pleasant feel. Despite its high flexibility, TPU-LW remains tear-resistant and elastic, allowing printed objects to return to their original shape after deformation. Thanks to its good adhesion and easy paintability, it is ideal for model building, cosplay, flexible wearables, and sports equipment. Whether for lightweight aircraft models or flexible protective components – TPU-LW offers you limitless design possibilities!

Features:

• Maximum foaming ratio of 200% allows for extreme weight reduction.
• Density and strength individually adjustable through temperature and extrusion factor adjustment.
• Fine matte surface minimizes visible layer lines and ensures a high-quality appearance.
• High elasticity allows a return to the original shape after deformation.
• Very good layer adhesion improves the stability of print objects.
• Easily paintable surface, ideal for creative projects.
• Material savings of up to 54% compared to conventional TPU.
• Vacuum-sealed packaging with desiccant
• Recyclable cardboard spool for environmentally conscious disposal

Application examples:

• Aircraft and ship models: Reduced weight for improved aerodynamics and longer flight times.
• Cosplay accessories: Lightweight and flexible armor parts that are comfortable to wear.
• Wearables and protective equipment: Perfect for orthopedic applications or sports protectors.
• Flexible damping elements: Usable for shock-absorbing components in vehicle models or machines.
• High-performance prototyping: Creation of ultra-light, customizable functional components.

Quick guide for printing with TPU-LW

• Disable retract: Turn off pulling movements in the slicer, as the TPU continues to foam in the hotend. Stringing is normal – Vase mode can help.
• Adjust the first layer: Set speed to 100% and disable the slowdown for small areas. Adjust extrusion rate (e.g., 58% at 260°C).
• Optimize adhesion: If the component adheres too strongly to the print bed, reduce the bottom layer extrusion value.
• Observe the maximum printing temperature: Do not operate PTFE tubes above 250°C – use a metal hotend for higher temperatures.
• Avoid discoloration: Too high temperatures can cause yellowing or nozzle clogging – reduce temperature if necessary.
• Ensure constant temperature: Perform PID tuning and disable speed reductions to ensure stable foaming.
• Fine-tune extrusion:
  • Higher temperature → stronger foaming → less extrusion required
  • Higher printing speed → less foaming → more extrusion required
  • Individually adjust printing parameters and optimize wall thicknesses in the model.

Bambu Lab AMS-compatible cardboard spool:

Our cardboard spools are perfectly tuned for use with the Bambu Lab AMS. The plastic coating of the cardboard running surface allows handling like conventional plastic spools – without an adapter. An environmentally friendly solution that does not neglect comfort.

• Perfect compatibility: Can be used directly in the Bambu Lab AMS without additional tools.
• Easy to handle: Thanks to the plastic coating of the cardboard running surface, usable like plastic spools.
• Environmentally friendly: Simple and ecological disposal via cardboard recycling routes.
