## Description

Product description High Flexibility & Toughness Siraya Tech Flex TPU Filament: Unleashing Unparalleled Flexibility & Durability for Your 3D Printing. Durable Siraya Tech Flex TPU 3D Printer Filament is durable, not easy to break, effortlessly supports substantial weight. Bendable Bend It, Twist It: Superior Flexibility Meets Exceptional Toughness. Discover the potential of Flex TPU Filament 85A for your most demanding projects. Easier to print Smooth Printing, Remarkable Results: Flex TPU's reliable printing experience opens a world of possibilities, from prototyping to finished products. 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.

Review: Really good TPU - It printed right off the bat without drying when I printed with my Bambu Lab H2C (followed instructions to remove PTFE and direct feed into the TPU hole). It sticks well to PLA so I printed a phone case and did other mixed TPU and PLA prints such as a game holder. Really happy with this filament. It holds up very well for my phone case. Love the white as it is very white.
Review: Love this filament! - Good stuff! Works great with our Adventurer 5M printer. Used for printing different vacuum tips for my home made pneumatic vacuum.

### ⭐⭐⭐⭐⭐ Really good TPU

### ⭐⭐⭐⭐⭐ Perfect Filament
*by S***E on January 15, 2025*

Printed on a Bambu A1 with a low friction spool adapter on the back spool holder. Make sure you super dry this filament and use a low friction spool adapter. The complaints I see are stringy and under extrustion, thats because they didnt dry it and have too much resistance pulling the filament in. As you can see in my photos perfect prints and absolutely zero stringing. If you have bad results its not the filaments faults its you.
