TPU-LW is the TPU material can be foamed during the printing process. By adjusting the printing temperature and speed, the foaming degree of the filament can be changed, so that the strength and density of the printed product can be adjusted in a personalized way. Foaming during the printing process makes the surface of the product has a fine frosted texture, and not easy to show the layer pattern. TPU-LW has good flexibility, hard to tear, and has good resilience. As a flexible foam material, the printed object is soft and skin-friendly, suitable for flexible wearable products and COSPLAY model printing.
Utilizing advanced physical microsphere foaming technology, TPU-LW achieves a remarkable maximum foaming ratio of up to 200%, offering precise volume expansion while significantly reducing the weight of your prints.Delivers exceptional wear and tear resistance. It ensures your 3D printed parts remain tough and intact even under heavy daily use.
Easily manipulate the foaming ratio via printing temperature settings to achieve varying degrees of softness. The Shore hardness can be seamlessly adjusted within the 77A to 93A range to suit diverse application needs.
Models printed with TPU-LW withstand repeated bending and intense stretching without breaking. Its outstanding elongation ensures parts remain highly resilient and structurally intact under stress.

The foaming rate varies at different temperatures. You will need to adjust the flow rate ratio based on the corresponding parameters; please refer to the foaming ratio chart for details.
The material foams and expands upon heating inside the nozzle, making retraction impossible to control. Retraction must be disabled during printing to prevent clogging caused by retraction moves.
We recommend printing only one model at a time to minimize travel moves and reduce stringing. (Since retraction cannot be controlled, some stringing is unavoidable.)
When foaming occurs, printing speeds should not change too abruptly. We recommend setting a uniform speed for all print moves (outer walls, inner walls, infill, supports, and top layers).
We do not recommend using the AMS with this flexible, lightweight material. We suggest using an external spool setup, placing the filament in a dry box during printing, and minimizing the length of the guide tube to ensure smooth feeding.
TPU filament absorbs moisture easily; we recommend drying it before printing. The recommended drying conditions are 55°C for more than 4 hours.
