What is TPU 95A HF Filament?
TPU 95A HF filament blends flexibility and rigidity to create durable, versatile 3D prints. With a shore hardness of 95A, this filament balances strength and softness, making it ideal for diverse printing applications.
Material Composition
TPU 95A HF filament is a thermoplastic polyurethane known for its elasticity, resistance to abrasion, and chemical stability. It is made from a combination of hard and soft segments, allowing it to flex without breaking. Its enhanced flow properties make it stand out in 3D printing.
Last weekend, I printed a phone case using TPU filament. The case came out strong yet flexible, protecting my phone from accidental drops. This blend of durability and flexibility highlights why TPU 95A HF filament is a game-changer in the 3D printing community.
Key Features and Advantages
Flexibility and Durability
TPU 95A HF filament offers a superior balance of flexibility and sturdiness. Its Shore hardness of 95A bends without breaking, making it ideal for functional prototypes. When I printed a custom phone case, the material provided excellent impact resistance while maintaining a snug fit. This filament’s flexibility ensures it can handle repeated stress without compromising its structural integrity.
Enhanced Printability
Printing with TPU filament can often be challenging, but TPU 95A HF significantly improves the experience. Its stable and consistent extrusion minimizes common issues like stringing and warping. From my experience, this filament adheres well to the print bed, reducing the frustration of failed prints. Users can expect reliable results even with complex designs.
Chemical and Abrasion Resistance
TPU 95A HF filament stands out for its resistance to chemicals and abrasion. It can withstand harsh environments without degrading, making it suitable for industrial applications. I used this filament for a project requiring contact with oils and solvents, and it performed exceptionally well. This filament’s durability against wear and tear makes it a dependable choice for various demanding scenarios.
Bambu Lab’s TPU 95A HF Filament
Bambu Lab TPU 95A HF filament is a game-changer in 3D printing, offering a blend of high-speed printability and robust material properties. Below, I break down its key features and standout elements.

Soft and Flexible
This filament is extraordinarily soft and flexible, making it ideal for impact resistance and pliability applications. It can repeatedly flex without breaking, perfect for custom-fit grips and soft-touch devices.
Outstanding Impact Resistance
This TPU filament handles significant stress with excellent impact resistance while retaining its form. It’s suitable for parts that endure frequent physical interactions, such as wearable gadgets or protective enclosures.
Consistent Diameter
The filament’s diameter is 1.75mm, and its tolerance is +/—0.03mm. The consistent diameter ensures smooth feeding and reliable printing, eliminating the need for constant adjustments.
Applications of TPU 95A HF Filament
Wearable Devices
TPU 95A HF filament shines in wearable devices due to its flexibility and skin-friendliness. I’ve used this filament to print custom-fit smartwatch bands, and the results were comfortable and durable. The material’s ability to flex without breaking makes it perfect for fitness tracker bands, insoles, and protective gear. Users appreciate the soft texture and strength, making TPU filament a go-to for wearables.
Automotive and Industrial Parts
In the automotive and industrial sectors, TPU 95A HF filament proves invaluable. I’ve printed durable gaskets and flexible hose connectors that withstand harsh conditions. Its high wear resistance and resilience make it ideal for parts like seals, bushings, and shock absorbers. Industrial prototypes also benefit from this filament’s consistent diameter and reliable performance, reducing downtime in production settings.
Consumer Products
For many consumer products, TPU 95A HF filament offers a blend of strength and flexibility. I’ve successfully printed phone cases that protect against drops while maintaining a sleek design. The filament is great for tool grips, toys, and flexible household items. Customers value these products’ durability and superior quality, enhancing day-to-day functionality.
Tips for Printing with TPU 95A HF Filament
Printer Settings
Let’s jump into the nuts and bolts. Set your printer’s hot end to 210-230°C for optimal extrusion. Bed temperature is best around 40-60°C to prevent warping. Stick to a slower print speed, about 30-40 mm/s, to maintain quality. Increase the retraction distance, around 2 mm, and reduce the retraction speed to avoid filament jams. Use a direct drive extruder if possible; it handles flexible filaments better than a Bowden setup.
Avoiding Common Issues
While printing with TPU filament, I learned that bed adhesion can get tricky. For better stickiness, use a PEI sheet or blue painter’s tape on the build plate. Stringing is another common problem; lowering the print temperature and fine-tuning retraction settings help minimize it. If you notice uneven extrusion, ensure the filament path is smooth and free from obstructions. Frequent checks during the print process help catch issues early.
Conclusion
I’ve noticed the TPU 95A HF filament’s impact firsthand. While working on a custom prototype, I struggled with other filaments that snapped or needed more flexibility. Switching to TPU filament solved my issues. It allowed for durable, flexible prints, making the entire process smoother. This filament’s elasticity and high-speed printability are game-changers in 3D printing.
