Bambu Lab TPU 75A (2.85mm) Series
An extremely soft material designed for wearable devices
Combining the exceptional softness of 75A hardness with a 2.85mm filament diameter and the FlexFeed extruder, it delivers a comfortable feel, efficient feeding, and stable printing performance for flexible material 3D printing.
An extremely soft cushioning layer for items that touch the body
TPU 75A offers excellent flexibility, cushioning, and elasticity, opening up new possibilities for 3D printing wearable devices and flexible functional parts.
From shoes and watch bands to cushioning structures, it supports designs intended for actual wear and use, not just display models.
Shoes and Insoles
By utilizing flexible structural design, you can create cushioned components for shoes.
Wearable Accessories
Consider using it for watch bands, flexible accessories that fit the body, and personalized designs.
Cushioning and Functional Parts
Ideal for designing parts that require bending, compression, and soft contact.
The value delivered by 75A softness: Compared to harder TPU materials, 75A is ideal for applications requiring a soft feel, bending deformation, and cushioning.
Faster, more stable printing of ultra-soft TPU with a 2.85mm diameter
Ultra-soft TPU can easily deform during feeding, which may affect extrusion stability.
Bambu Lab uses a 2.85mm filament diameter and, when combined with the FlexFeed extruder, is optimized for a design suitable for feeding flexible materials.
According to product data, under specific in-house lab test conditions, the combination of FlexFeed and TPU 75A reaches a volumetric flow rate of approximately 10 mm³/s, delivering about three times the performance of conventional 1.75mm extrusion setups.
More stable filament feeding contributes to improved printing efficiency for ultra-soft TPU.
About the tests: Both the flow rate and the approximately 3x performance comparison are based on in-house lab tests under specific conditions. Actual results may vary depending on the printer configuration, model, material condition, and slicing settings.
A natural matte finish. Soft to look at, and even softer to the touch
General TPU filaments can sometimes produce a highly glossy surface after printing. By adjusting the formulation, TPU 75A achieves a more natural matte texture.
In addition to a soft feel, it brings a premium, delicate appearance to wearable products.
Natural matte texture: Compared to some TPUs with a strong surface gloss, TPU 75A emphasizes a soft, delicate look and feel. It is ideal for designs where comfort during contact and the quality of the appearance are important.
Excellent durability that withstands everyday bending and compression
TPU 75A is not only soft, but can also be used as a material for items that are repeatedly bent or compressed, and items touched daily.
From wearable devices and cushioning pads to flexible functional parts, the material's flexibility can be combined with a wide range of structural designs to meet the needs of a broad range of applications.
For 3D printing projects that want to balance comfort, elasticity, and everyday usability, TPU 75A offers an even softer design option.
