Black TPU 75A Filament for 3D Printer 1 kg | 1.75 mm
Black TPU 75A Filament for 3D Printer is a very soft, flexible and elastic material for FDM/FFF 3D printing. TPU with 75A Shore hardness is noticeably softer than TPU 85A and much more flexible than TPU 95A, making it suitable for parts that require maximum elasticity, softness, shock absorption and repeated bending.
⚫ Color: Black
Black TPU 75A has a universal technical appearance and is suitable for soft functional parts, flexible pads, dampers, gaskets, seals, protective elements, cases and prints where a practical dark color is required.

🔧 3D Printer Compatibility
- ✅ Suitable for FDM/FFF 3D printers using 1.75 mm filament
- ⚙️ Direct drive extruder is strongly recommended for TPU 75A
- 🧵 Bowden systems are usually not recommended for TPU 75A because of very soft filament feeding
- 🔩 The filament path should be short, constrained, free and without sharp bends
- 🐢 For stable printing, use low speed and minimal feeding pressure
🧰 Best Applications
- 🛡️ Soft dampers, shock absorbers and vibration-reducing elements
- 🔧 Flexible gaskets, seals, bushings and soft mounts
- 📱 Cases, protective pads and soft accessories
- 👟 Shoe elements, soft inserts, grips and soft-touch parts
- 🧪 Prototypes of very soft elastic products
- ⚙️ Functional parts that require maximum flexibility
💡 Printing Tips
- 🐢 Print very slowly: TPU 75A is softer than TPU 85A and needs especially stable feeding.
- ⚙️ Disable retraction if possible or use the minimum value.
- 🧵 Avoid unsupported filament sections between the drive gear and the hotend.
- 🔩 Use a short and well-guided filament path.
- 📦 Store TPU in a dry place, preferably in a sealed bag with silica gel.
❓ FAQ
TPU 75A is softer than TPU 85A and much softer than TPU 95A. It is better for very flexible parts, but it requires more careful print tuning. Yes, but a direct drive extruder is recommended. TPU 75A is usually more difficult for Bowden systems than TPU 85A and TPU 95A. Yes, black TPU 75A is well suited for soft gaskets, dampers, shock absorbers, protective pads and highly elastic functional parts. TPU 75A is very soft, so at high speed it may buckle or feed inconsistently. Low speed helps achieve smooth extrusion.How is TPU 75A different from TPU 85A and TPU 95A?
