Description
TPU90A 3D Printing Filament
3D META's TPU90A 3D printing filament is a medium-soft, flexible thermoplastic polyurethane that strikes the perfect balance between rubber-like flexibility and ease of printing. At Shore 90A hardness, TPU90A is firmer than soft TPU85A but still highly flexible — making it easier to print on a wider range of printers (including some Bowden setups) while still delivering excellent elasticity, impact resistance, and abrasion resistance. It's the ideal first-choice TPU for users new to flexible printing, and the go-to material for grips, cases, gaskets, and functional flexible parts. Like all 3D META filaments, TPU90A is manufactured to strict quality standards and supplied on recyclable plastic spools.
Key Features of TPU90A 3D Printing Filament
• Balanced Shore 90A Hardness: Flexible enough for elastic, rubber-like parts but firm enough for easier printing.
• Excellent Elasticity and Recovery: Stretches, bends, and returns to shape repeatedly without fatigue.
• Outstanding Abrasion and Tear Resistance: TPU's hallmark wear performance for parts that take real-world use.
• Manufactured with High-Quality Materials: Premium TPU base for reliable extrusion and consistent flexibility.
• Easier to Print Than Soft TPUs: Firmer hardness makes TPU90A more forgiving on a wider range of printers, including most direct-drive and some Bowden setups.
• Strong Layer Adhesion: Excellent inter-layer bonding for durable, fatigue-resistant flexible parts.
• Strict QA Manufacturing: Every batch is checked for diameter, hardness, and print performance.
Applications for TPU90A 3D Printing Filament
TPU90A is the most versatile flexible filament in the 3D META range — ideal for users who want flex without the printing challenges of softer TPUs:
• Phone Cases and Protective Covers: Flexible cases that absorb impact while protecting devices.
• Functional Flexible Parts: Hinges, flexures, and flexible mechanisms in prototypes and production parts.
• Grips and Handles: Soft-touch grips for tools, controllers, and accessories.
• Seals and Gaskets: Custom seals and gaskets for prototype and low-volume applications.
• Sporting and Lifestyle Accessories: Watch straps, wristbands, sandal soles, and durable wearable accessories.
Note: TPU is hygroscopic — drying before every print is essential. A direct-drive extruder is recommended for best results, though TPU90A is more tolerant of Bowden setups than softer TPUs.
Storage and Drying for TPU90A Filament
TPU absorbs moisture rapidly and prints best when thoroughly dried:
• Store in a Cool, Dry, Dark Environment: Use airtight containers or vacuum-sealed bags with fresh desiccants at all times.
• Drying Recommendations: Dry TPU90A before every print. Use a filament dryer, food dehydrator, or enclosed 3D printer at 50–60°C for 6–8 hours.

FAQs
1. Should I choose TPU90A or TPU85A?
TPU90A is firmer, easier to print, and more versatile — start here if you're new to flexible filaments or want a forgiving general-purpose TPU. Choose TPU85A when you need maximum softness and elasticity for grips, seals, or skin-contact wearables.
2. What temperature should I print TPU90A at?
Print at 220–240°C with a heated bed at 50–60°C. Keep print speeds between 20–40 mm/s and tune retraction carefully — small retractions (1–2 mm) usually work best.
3. Can I use TPU90A on a Bowden printer?
Yes — TPU90A is firmer than softer TPUs and works on many Bowden setups, though direct-drive is still preferred for best results. Expect to reduce print speed and tune retraction carefully.
4. Is TPU90A suitable for phone cases?
Yes — TPU90A is a popular choice for phone cases and protective covers. It absorbs impact well, stretches over devices for a snug fit, and resists scuffs and tears.
