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.

Superior Flexibility & Toughness: Siraya Tech’s Flex TPU 85A 3d printer filament excels in flexibility and elasticity, making it ideal for durable, bendable 3D prints. Perfect for softer, pliable projects.
ISO 10993 Tested: Our Flex TPU 85A has undergone testing according to ISO 10993-10, -5, and -23 protocols. These tests evaluate biological responses to materials, providing data on potential biocompatibility. This testing helps ensure peace of mind when printing for external-use wearables and devices.
High Flow, High Speed: Designed for high-flow, Flex TPU 85A filament enables quicker prints than typical TPU 95a, blending speed with stellar outcomes. For the optimal printing experience, we recommend using a direct drive style extruder.
Long-Lasting Quality with Special Packaging: Our Flex TPU 3d printer filament is sealed in moisture-resistant aluminum resealable bags, preventing water absorption and ensuring up to 3 years of shelf life and consistent print quality.
Versatile for Various Applications: From custom footwear to medical devices, this Flex TPU filament 1.75mm meets diverse needs in creative and industrial settings. And compatible with most 3D printers, it guarantees a smooth and reliable printing process, suitable for both beginners and experts.
