Flexible High-Strength TPU Filament
This 1.75mm TPU filament offers excellent elasticity and toughness, capable of bending up to 360 degrees. Made from thermoplastic polyurethane, it combines hard and soft copolymer segments to provide durability and flexibility ideal for automotive, sporting, and electronic applications.
Its transparency, resistance to oil, grease, and abrasion make it a versatile material for protective cases, footwear, drive belts, and more.
Smooth, Stable Printing Performance
Formulated to deliver clog-free and bubble-free extrusion, this filament ensures consistent layer-to-layer adhesion and a smoother printing experience.
Dimensional accuracy is maintained at a tight tolerance of +/- 0.05 mm, which helps achieve precise, reliable prints every time.
- No bubbles or clogs during printing
- Good toughness and stable extrusion
- Optimized for flexible print designs
Wide Printer Compatibility
Compatible with a broad range of 3D printers using 1.75mm filament including EasyThreed, Makerbot, Prusa, Ultimaker, and Raise3D.
Designed to run well with most consumer and professional machines configured for flexible TPU materials.
- Fits most 1.75mm 3D printers
- Supports printers like Makerbot, UP, Leapfrog
- Easy to integrate in various printing systems
Printing Guidelines and Considerations
Recommended printing speed is between 30-60mm/s with extruder temperature from 190–230℃.
Bed temperature can be room temperature or up to 40℃. Printing very tall or thin models is not advised due to filament flexibility causing potential swaying.
Optimal feeding requires a non-spring wire feed system with short distance between drive gear and nozzle to avoid feeding failures.
- Print speed: 30-60mm/s
- Extruder temp: 190-230℃
- Bed temp: room temperature to 40℃
- Avoid printing very tall models

Product FAQ
Frequently asked questions
01 What is the diameter tolerance of this TPU filament?
The filament diameter is 1.75mm with a tolerance of +/- 0.05mm for consistent flow.
02 What printing temperatures are recommended?
Extruder temperature should be set between 190℃ and 230℃ for optimal printing.
03 Is this TPU filament suitable for flexible parts?
Yes, TPU is a highly flexible material capable of bending 360 degrees, ideal for flexible prints.
04 Can this filament be used in any standard 1.75mm 3D printer?
It is compatible with most 1.75mm specification 3D printers including Makerbot, Prusa, Ultimaker, and others.
05 Does the filament contain any hazardous chemicals?
No, this filament is non-toxic and complies with environmental standards, free from hazardous substances.
06 Is the filament resistant to oils and abrasion?
Yes, TPU material offers resistance to oil, grease, and abrasion, ensuring durable prints.
07 What printing speed is recommended for this filament?
Printing speeds between 30mm/s and 60mm/s are suggested for smooth extrusion.
08 What should I consider about feeding mechanism when printing?
Flexible filament demands a non-spring type wire feeding mechanism with short distance between gear and nozzle to avoid feeding issues.
09 Is vacuum packaging used for this filament?
Yes, filaments are vacuum packaged with desiccant to absorb moisture, although some air may enter after transport without affecting quality.
10 Can I print high models with this filament?
Printing very tall models is not recommended as flexible filament can cause upper parts to sway.
