Bambu Lab PLA Tough+ Cyan 1 kg

Bambu Lab PLA Tough+ is a next-generation premium PLA filament that combines the ease of printing of PLA with durability and toughness close to ABS. Thanks to its rich cyan (light blue) color, it is ideal for both functional prototypes and design parts that must withstand stress.

Main advantages of the material

• Up to 2x higher layer adhesion than standard PLA – significantly lower risk of breaking at the layer lines.
• Toughness at ABS level – resists impacts, drops, and repeated stress better.
• High resistance to repeated bending – suitable for flexible elements, clips, latches, and mechanical joints.
• Easy to print like classic PLA – minimal warping, excellent dimensional accuracy, no enclosed chamber required.
• Full compatibility with Bambu Lab AMS – the filament is supplied on a reusable spool with an RFID tag, which automatically loads settings in Bambu Lab printers.

Recommended use

PLA Tough+ Cyan is especially suitable for:

• RC models (cars, planes, drones – bumpers, arms, battery holders)
• Functional and technical parts (jigs, holders, mounting fixtures, covers, connectors)
• Flexible and stressed components (clips, latches, hinges, flexible joints)
• Prototypes for functional verification – when regular PLA is not tough enough
• Design and decorative parts where higher durability and an attractive cyan shade are required

Printing properties

PLA Tough+ is designed to print as similarly as possible to classic PLA:

• Good bed adhesion, low risk of warp
• Very good layer adhesion even at lower chamber temperatures
• Suitable for open and closed FDM printers
• Optimized profiles are available in Bambu Studio for Bambu Lab printers

Technical parameters

The stated values are typical manufacturer values for Bambu PLA Tough+ material.

• Material: PLA Tough+ (modified PLA)
• Color: Cyan (light blue)
• Filament diameter: 1.75 mm ± 0.03 mm
• Net weight: 1 kg of filament on a spool
• Spool diameter: standard Bambu Lab spool (with RFID tag)
• Recommended nozzle temperature: approx. 220–245 °C (depending on profile and printing speed)
• Recommended bed temperature: approx. 35–60 °C
• Compatibility: all FDM 3D printers with 1.75 mm diameter; full support for Bambu Lab AMS systems

Mechanical properties (typical values)

• Higher impact toughness compared to standard PLA (toughness in the XY plane is significantly higher than PLA Basic)
• Significantly stronger layer adhesion (Z) than regular PLA and ABS
• High dimensional stability – suitable for parts with precise dimensions

Tips for successful printing

• For maximum toughness, print with recommended Bambu Lab profiles (higher nozzle temperature, sufficient layer height and perimeter width).
• Store the filament in a dry place (sealed box, silica gel) to minimize moisture absorption.
• For better bed adhesion, textured PEI, smooth PEI or another surface for PLA is suitable.

Who is Bambu Lab PLA Tough+ suitable for

This filament is ideal for users who want more than regular PLA, but do not want to switch to more demanding materials like ABS or nylon. It is suitable for hobbyists, engineers, prototyping workshops, and small series of functional parts where the combination of ease of printing and durability is key.

Key features:

• Reinforced PLA Tough+ filament with toughness close to ABS
