Bambu TPU 85A Filament with Spool - 1.75mm - 1kg - Ultra-Soft Flexible Filament Sorta Seafoam

Step into a world of ultra-flexibility with TPU 85A — the softest TPU filament in the Bambu Lab lineup. Engineered for exceptional elasticity, resilience and bounce-back, it's perfect for printing parts that cushion, bend and absorb impact. Whether you're designing protective cases, wearables, soft grips, or playful fidget toys, this filament brings premium flexibility to your 3D printing palette. 

Product Features:

Softest Shore rating in range — with a Shore hardness of 85A, TPU 85A offers unmatched flexibility and "soft touch" feel. 

Impact-absorbing & wear-resistant — designed to flex, compress and rebound, making it ideal for protective shells, cushions, or shock-absorbing components. 

High elasticity — elongation at break exceeds 700% for TPU 85A. 

Great material compatibility — while TPU 85A is focused on ultra softness, it still works well in many prints where you might pair it with harder materials (note: multi-material prints have specific restrictions). 

Quality spool & packaging — delivered on a reusable high-temperature spool and vacuum sealed with desiccant to maintain filament integrity. 

Sharp colour options — available in soft and bold colours (e.g., Neon Orange, Light Cyan) to bring aesthetics into your flexible prints. 

Technical Specifications:

• Filament diameter: 1.75 mm ± tolerance 
• Net weight: 1 kg (standard spool) 
• Shore hardness: 85A 
• Density: ~ 1.18 g/cm³ 
• Tensile strength: ~ 12.0 ± 0.8 MPa 
• Breaking elongation: >700% 
• Recommended nozzle temp: ~ 220-250 °C 
• Recommended bed temp (with glue): ~ 30-35 °C 
• Printing speed: generally < 200 mm/s for optimal results (slower speeds recommended due to flexibility) 
• Compatibility note: Not compatible with AMS / AMS-Lite multi-material feeders. 

Ideal Uses:

• Cushioned smartphone or device cases that absorb drops & shocks
• Wearable soft-gear: straps, bands, flexible joints
• Bumpers, grips, handles, and protective shells requiring soft contact surfaces
• Prototyping cushions, pads or flexible elements in assemblies
• Fun & playful prints: squishy toys, flexible fidgets, custom elastics

Printing & Handling Tips:

• Dry your filament: TPU 85A is highly moisture-sensitive. Dry at ~70 °C for ~8 hours before use. 
• Print slow: Lower print speeds (e.g., 80 mm/s) help reduce issues like clogging and stringing. 
• Use the right nozzle: Recommend 0.6 mm or 0.8 mm hardened steel nozzles for best reliability. Avoid ultra-fine nozzles (<0.4 mm) with very soft filament. 
• Adhesion matters: Use glue or adhesive on smooth/textured PEI build plates; bed temp ~30-35 °C. 
• Store properly: Keep sealed with desiccant; aim for humidity <20% RH for best results. 

If you're looking for the softest, most cushioning flexible filament in your toolkit, TPU 85A delivers. While many flexible filaments compromise softness for structure, this one flips the script—giving you true elastomer-like elasticity and bounce, without abandoning printability or durability. Whether for wearable comfort, protective parts, or that perfect squishy toy concept, this filament stands out.
