What makes Flex TPU different?

Up to 5x speed

Compared with similar TPU filaments, the material of Flex TPU has been upgraded, making it easier to extrude and the printing speed can be increased by 5X.

Further moisture protection

Use vacuum aluminum-based packaging, which is more moisture-proof than ordinary transparent bags. And the sealing strip allows reinstallation after removal.

Flex TPU Filament is stronger and more durable

The material has been upgraded, and the filament has strong toughness and can easily lift heavy objects.

Prints feel softer to the touch

The printed surface is clean and smooth, and the Shore hardness of 85A gives filament printing a soft feel closer to silicone.

Preparing for Printing

(1) Printer Compatibility

Flex TPU 85A is optimized for FDM printers equipped with direct drive extruders, which are located on the toolhead for enhanced filament control. This setup is crucial for successful TPU printing.

For best results, mount the filament directly above the extruder to facilitate the shortest and most efficient path from the spool to the extruder, thus significantly enhancing the print quality and success rate.

(2) Print Bed Preparation

A clean, level print bed is essential. We recommend a heated bed temperature ranging from 20°C to 50°C, adjusted according to your printer’s capabilities.
