TPU Lightweight (TPU-LW) eSun Filament

Description

TPU-LW eSun Filament for 3D Printer

eTPU-LW is a TPU material that can expand into foam during the printing process. The printing temperature and speed can be adjusted to control the degree of foaming, resulting in customizable strength and density of the printed object. The foaming during printing creates a textured surface and reduces the visibility of printing lines.
eTPU-LW offers excellent flexibility, tear resistance, and resilience due to its elastic foam nature. Printed objects are soft and skin-friendly, making it ideal for wearable products requiring flexibility, as well as printing models for cosplay.

Product highlights

  • Reduce weight by up to 50%: With a maximum foaming volume ratio of up to 172% (depending on settings), you can save material and create significantly lighter parts. Ideal for drones, RC model airplanes, or parts requiring lightweight construction.

  • Custom Density: You can freely control the bubble level (and Shore Hardness approximately 93A-77A) by simply adjusting the printing temperature and speed to achieve the desired strength and softness of your printed object.

  • Delicate Frosted Texture: The foaming process helps reduce layer lines, resulting in a beautiful matte finish and making painting easier.

  • Highly flexible and durable: Excellent flexibility, tear resistance, and quick shape recovery. Ideal for flexible wearables and impact-resistant parts.

🎯 What types of applications is it suitable for?

  • Remote-controlled vehicles: drones, RC airplanes, and lightweight RC cars.

  • Cosplay and Props: Armor or cosplay accessories that require softness and lightweight material.

  • Wearable components: Soles, flexible grips/handles, parts in contact with skin.

  • Flexible mechanical parts: flexible joints, seals, shock absorbers.

🛠️ Basic Printing Tips for Best Results

Settings Recommended temperature range
Nozzle temperature 220°C - 250°C
Bed temperature 40°C - 60°C
Printing speed 20 - 40 mm/second
Retraction It should be disabled to prevent clogging.
Flow Rate

Adjust as needed (e.g., 58% at 260°C for maximum foaming).

Note: For optimal foam formation and lightweight results, please experiment with adjusting the extrusion rate and temperature to suit your printer.

Net weight: 0.75 kg/roll

Instructions for use

  • Disable retraction in the slicer software to prevent gaps inside the nozzle that could cause clogging. Because TPU-LW continues to expand as foam inside the high-temperature nozzle, retraction becomes ineffective. Filament buildup during printing is normal, and Vase Mode can be used to mitigate this effect.
  • Set the first layer speed to match the actual printing speed of 100% and disable the first layer and small area deceleration functions. The first layer extrusion rate should be set to match the actual extrusion rate after foaming (e.g., 58% at 260°C ). If the part adheres too tightly to the print bed, adjust the bottom valve during printing.
  • Check the maximum temperature the printer can handle (PTFE tube printers should not be operated above 250°C for extended periods) as this may cause clogging. If printing at temperatures above 250°C is required, use a high-temperature compatible printer with a metal hotend.
  • Yellowing or nozzle sticking after printing at high temperatures is normal. Lowering the printing temperature can help reduce this problem.
  • Optimize your printer's PID settings to maintain a constant temperature. Disable the automatic speed reduction function, as changes in temperature or printing speed can affect foam formation and result in visible print layers.
  • The foam formation rate is directly related to the printing temperature.
    • At a constant speed: Higher temperature = higher foaming rate (requires lower extrusion rate).
    • At a constant temperature: Higher speed = lower foaming rate (the extrusion rate must be increased).

Adjust the extrusion settings, temperature, and speed to suit your printing needs, and compare the model wall thicknesses to find the optimal settings.
