AI Verdict
This 1.75mm, 95A Shore hardness TPU filament is for hobbyists needing a flexible material with ±0.03mm dimensional accuracy for functional parts.
This filament is a strong fit for anyone needing a flexible material with specific dimensional accuracy and a balanced Shore hardness. Its 95A Shore hardness and ±0.03mm tolerance make it suitable for functional parts requiring both flexibility and consistent dimensions. The clog-free design and pre-drying process aim to simplify the printing experience.
If you need even softer, more pliable prints, look for TPU filaments with a lower Shore hardness, like 85A.

Pros
- The 95A Shore hardness balances elasticity and toughness for parts that withstand daily wear and impacts.
- It maintains a 1.75mm diameter with a tight ±0.03mm tolerance, ensuring consistent extrusion.
- The filament comes vacuum-sealed with desiccants and undergoes a 24-hour pre-drying process to minimize clogs and bubbles.
- Enhanced layer bonding technology promotes tight interlayer adhesion, reducing delamination risks.
- It resists cracking, fading, wear, and oil, maintaining structural stability over time.
- The filament is compatible with most 1.75mm FDM 3D printers and optimized for direct-drive extruders.
Cons
- Users report needing to print at painfully slow speeds to achieve optimal results.
- Stringing can be an issue, requiring careful retraction settings and potentially lower nozzle temperatures.
- The filament requires careful storage in sealed containers with desiccants after opening to prevent moisture absorption.
- Some users find they need higher nozzle temperatures than recommended, sometimes up to 245°C, for better layer adhesion.
- Smooth PEI print beds can lead to excessive adhesion, potentially damaging the print surface upon removal.
Dimension Scores
The filament boasts a 1.75mm diameter with a ±0.03mm tolerance, validated by an advanced CCD diameter inspection system.
It features a patented clog-free formula and 24-hour pre-drying, aiming for smooth extrusion, but requires slow print speeds and careful drying after opening.
The 95A Shore hardness allows for a range of applications from phone cases to robotics parts, blending softness with durability.
Crafted from TPU with 95A Shore hardness, it offers high elasticity, wear resistance, oil resistance, and anti-aging properties.
Best For
- Printing flexible phone cases and watch bands that require elasticity and durability.
- Creating robotics parts and flexible toys that need to withstand impacts and deformation.
- Producing insoles and functional prototypes requiring a balance of softness and structural integrity.
- Users new to TPU printing, due to its reported ease of use and clog-free design.
Not Recommended For
- High-speed 3D printing applications, as slow print speeds are often necessary.
- Environments with high humidity without dedicated filament drying solutions.
- Users unwilling to experiment with print settings to mitigate stringing and optimize adhesion.
Watch Out For
- Expect to print at 20-40mm/s, as going faster often leads to print failures and poor quality.
- If you're using a smooth PEI plate, you might need to switch to a textured one or use glue stick to prevent prints from sticking too aggressively and damaging the surface.
- You'll likely need to dry this filament at 65-70°C for 8+ hours if it's been exposed to humidity, otherwise, you'll get bubbles and poor prints.
- Some users report needing to increase nozzle temperature by 10-15 degrees above the recommended 180-210°C, especially with steel nozzles, to get proper layer adhesion.
- Be prepared for some stringing; managing it requires tweaking retraction settings and potentially lowering nozzle temperatures.

What Buyers Say
Many users find this Geeetech TPU surprisingly easy to print with, even for those new to flexible filaments, which is a big win for TPU. The main trick seems to be printing it slow, like really slow, and making sure it's dry. Some folks have had to bump up their nozzle temps a bit beyond the recommendations to get solid layer adhesion, especially if they're running a steel nozzle. The filament's ability to resist cracking and fading over time is a recurring positive, making it a contender for functional parts.
“Man, this stuff prints way easier than I thought TPU would, but seriously, you gotta slow it down to a crawl or it's just a stringy mess. And dry it, always dry it!”
Common Praise
- The filament's consistent 1.75mm diameter and ±0.03mm tolerance result in fewer print failures.
- It adheres well to the print bed, with some users noting it sticks better than other filaments they've tried.
- The 95A Shore hardness provides a good balance of flexibility and sturdiness for functional prints.
- Prints show strong layer adhesion with minimal warping, even on larger objects.
- The vacuum-sealed packaging with desiccant helps keep the filament dry before use.
- It produces durable, tear-resistant prints that maintain characteristics under stress.
Common Complaints
- Stringing can be a persistent issue, requiring significant tuning of retraction settings.
- Printing too fast leads to poor quality and failed prints, necessitating very slow print speeds.
- The filament is prone to absorbing moisture, requiring diligent drying and storage after opening.
- Some users experience issues with it sticking too well to smooth print surfaces, causing damage upon removal.
- Achieving optimal layer adhesion sometimes requires higher nozzle temperatures than the stated recommendations.
Ownership Tips
- After a few weeks, you'll notice how crucial a filament dryer is for consistent results, especially in humid environments.
- You'll probably end up with a dedicated profile for this TPU, tweaking retraction and speed way down from your other filaments.
- The clear blue color looks pretty cool, but it can make it harder to see print imperfections compared to opaque colors.
- You'll quickly learn that a textured build plate is your best friend with this stuff to avoid ripping up your smooth surfaces.
- The elasticity holds up well over time for things like phone cases, they don't just stretch out and get loose.
Frequently Asked Questions
What is the recommended nozzle temperature for this filament?
The recommended nozzle temperature is between 180-210°C, though some users find better results at 230-245°C, especially with steel nozzles.
Do I need a heated bed for printing with this TPU?
Yes, a heated bed is recommended at 50-70°C. Some users suggest 40-60°C.
How should I store this filament after opening?
Store it in sealed containers with desiccants to maintain humidity below 20% RH and prevent moisture absorption.
Is this filament compatible with all FDM 3D printers?
It is fully compatible with most 1.75mm FDM 3D printers, including desktop and industrial models, and is optimized for direct-drive extruders.
Can this filament be used for phone cases?
Yes, its 95A high-elasticity and wear-resistant properties make it ideal for flexible applications like phone cases.
Buying Guide
When you're looking at TPU filament, you're basically buying rubber for your 3D printer. It's squishy, it bends, and it's tough. You need to think about how flexible you want your final print to be, because that changes the 'Shore hardness' number. Also, TPU loves to soak up moisture from the air like a sponge, so keeping it dry is a huge deal for good prints. If it's wet, you'll get bubbles and weak parts.
Shore 95A Hardness
This number tells you how hard or soft the material is, like how a car tire is harder than a rubber band. 95A is on the firmer side for TPU, meaning it's flexible but still holds its shape well, good for things that need to bend but not flop around.
1.75mm Diameter with ±0.03mm Tolerance
This is about consistency. Imagine trying to draw a perfect line with a pencil that keeps changing thickness; your printer has the same problem with inconsistent filament. A tight tolerance like ±0.03mm means the filament's thickness stays super consistent, which helps your printer extrude smoothly and make accurate parts.
Clog-Free & Bubble-Free
This isn't just marketing fluff; it means the filament is designed to flow smoothly without getting stuck (clog-free) and without moisture causing steam bubbles in your nozzle (bubble-free). Bubbles lead to weak, ugly prints, and clogs are just frustrating print failures.
Alternatives
If this filament isn't flexible enough, search for TPU with a Shore hardness closer to 85A or 90A. If you need something more rigid but still impact-resistant, look for PETG or a harder TPU like 98A.
