SUNLU TPU 1.75mm Flexible 3D Printer Filament, 1kg Black (95A) — High-Speed, Wear-Resistant

SUNLU 1.75mm TPU (95A) is a high-speed flexible 3D printing filament that balances softness and toughness for durable, elastic prints.

If you need a reliable flexible filament for functional parts, wearable accessories, or shock-absorbing components, SUNLU’s TPU delivers consistent dimensional accuracy and faster print speeds than typical TPU materials. This 1 kg spool in black uses a 95A Shore hardness formula designed to resist wear, oil and aging while maintaining excellent layer adhesion and surface finish. The filament is vacuum-sealed for moisture protection and tuned for broad compatibility with most 1.75 mm FDM printers.

How quickly can I print with this TPU without losing quality?

SUNLU’s TPU is formulated for higher-speed printing so you can increase throughput while keeping good surface quality and bonding between layers. Recommended settings push speed more than standard flexible filaments but still prioritize controlled extrusion to avoid stringing.

• Nozzle temperature: 210–230°C for stable flow
• Print speed: 80–120 mm/s for fast yet reliable results
• Bed temperature: 50–60°C to improve first-layer adhesion
• Diameter tolerance: ±0.03 mm for consistent feeding

Will prints be durable and elastic enough for wearable or impact parts?

The 95A Shore rating gives the filament a firm-but-elastic feel suitable for items that must flex and recover, like watch bands, phone cases, insoles, and drone bumpers. Parts show strong resistance to abrasion and oils, and the material resists premature aging under normal use.

• High elasticity for repeated flexing and shock absorption
• Good wear and oil resistance for everyday use
• Anti-aging formulation to extend part lifespan
• Suitable for seals, gaskets, and protective casings

How easy is SUNLU TPU to print and finish?

SUNLU TPU is engineered for user-friendly printing: it feeds reliably, bonds well between layers, and gives a smooth finish with minimal post-processing. The filament’s tight diameter tolerance reduces jams and under/over extrusion issues on most Bowden and direct-drive extruders when properly tuned.

• Excellent layer adhesion for strong interlayer bonds
• Smooth surface appearance with low pilling or bubbling
• Vacuum packaging to prevent moisture-related print defects
• Compatible across a wide range of 1.75 mm FDM printers

What printer setup changes improve results with this flexible filament?

Optimizing printer settings helps avoid common flexible-filament issues like stringing or feeding problems. Simple adjustments—such as slower retractions, a well-leveled bed, and correct temperature—produce clean, functional parts with consistent dimensions.

• Lower retraction distance and speed to reduce jams and oozing
• Use a direct-drive extruder or tuned Bowden setup to improve feed control
• Print with a brim or adhesive on the bed for secure first layers
• Store spool in dry conditions; reseal after opening or use a filament dryer

Who this is for: SUNLU 95A TPU filament is aimed at makers, small manufacturers, hobbyists and designers who need a robust flexible material for wearable accessories, protective components, soft robotics parts, and functional prototypes. If you want faster flexible printing with consistent diameter control and strong layer bonding, this 1.75 mm black spool gives the balance of performance and convenience for everyday production and creative projects.
