Product description
Bambu Lab TPU 90A Blaze 1kg – flexible TPU with a unique gradient
Bambu Lab TPU 90A Blaze is a high-quality thermoplastic polyurethane (TPU) with a Shore hardness of 90A, developed directly by the printer manufacturer Bambu Lab. It combines high flexibility, excellent resistance to abrasion and tearing, and sufficient structural strength for functional parts.
The Blaze color variant offers a unique soft color gradient that occurs only once per entire 1kg spool – ideal for larger models, fashion, footwear, wearable accessories, and design parts where the smooth color transition stands out.
Key Features
- Shore hardness 90A – balanced ratio of flexibility and strength, suitable for functional parts
- Unique Blaze gradient – smooth color transition that appears only once on a spool
- High resistance to abrasion and material fatigue – suitable for parts exposed to repeated stress
- Excellent flexibility and shock absorption – ideal for bumpers, grips, handles, protective covers
- Possibility of multi-material printing with PLA/PETG (on compatible Bambu dual nozzles)
- Supplied on a high-temperature reusable Bambu spool – robust, well-ventilated spool
- Diameter 1,75 mm ± 0,05 mm – precise tolerance for reliable operation in the extruder
- Recommended nozzle 0,4 / 0,6 / 0,8 mm – universal use according to detail and speed needs
Typical Use
Bambu TPU 90A Blaze is particularly suitable for:
- Protective cases and covers (phones, electronics, sensors)
- Shock absorbers, bumpers, corner protectors
- Handles, grips, ergonomic handles and tool grips
- Soles and shoe parts, sports equipment, wearables
- RC tires, pads, damping inserts
- Flexible couplings and functional mechanical parts that must bend but not break
Thanks to the soft one-time Blaze gradient, the filament is also popular for:
- Fashion and design models
- Decorative and functional parts with a strong visual effect
Printing Properties
Bambu Lab TPU 90A is designed primarily for Bambu Lab X/P/A/H2D printers, but it can also be used on other FDM printers capable of reliably printing medium-hardness TPU.
General recommendations (indicative, adjust according to specific printer and profile):
- Material: TPU (thermoplastic polyurethane)
- Hardness: Shore 90A
- Diameter: 1,75 mm ± 0,05 mm
- Filament weight: 1 kg
- Recommended nozzle temperature range: approx. 210–240 °C
- Recommended bed temperature: approx. 35–45 °C (for Bambu Smooth/Textured PEI plates)
- Recommended printing speed: lower than for PLA/PETG (to reduce stringing and ensure precise dosing)
- Recommended nozzles: 0,4 / 0,6 / 0,8 mm (0,2 mm and HF nozzles are not recommended for TPU 90A)
- Recommended plates: smooth PEI, textured PEI, usually without the need for glue
\nWarning: TPU is a hygroscopic material – it is advisable to dry the filament before printing, especially if it has been exposed to moisture for a long time. Damp TPU causes bubbles, a matte surface, and reduced strength.
Advantages of TPU 90A compared to softer TPUs
Compared to softer TPUs (e.g., 85A), Bambu TPU 90A offers:
- Better feeding in standard extruders – lower risk of filament tangling and clogging
- Higher structural strength – parts hold their shape better, deforming less under load
- Easier printing on a wider range of printers compatible with 90A materials and harder
This makes it a suitable choice for users who want functional flexible parts but also need reliable printing without extremely demanding tuning.
Summary
Bambu Lab TPU 90A Blaze 1kg is an excellent choice for anyone looking for:
- Premium TPU filament with Shore hardness 90A
- Unique, one-time Blaze color gradient for an attractive visual result
- High resistance to wear, tearing, and repeated stress
- Full compatibility with the Bambu Lab ecosystem and high-quality profiles in Bambu Studio
The ideal combination for functional flexible parts and design projects where both performance and appearance count.
