Bambu Lab PLA Tough+ Cyan 1kg

Product Description

Bambu Lab PLA Tough+ Cyan 1kg is a premium PLA filament developed for real-world use where standard PLA is not enough. The material is engineered to withstand impacts, drops, and repeated stress, while maintaining the ease of printing and dimensional accuracy typical of PLA.

PLA Tough+ achieves toughness at the level of ABS and offers up to 2× higher interlayer strength compared to standard PLA. This makes it suitable for functional parts that are frequently used, handled, or may come into contact with mechanical loads – for example, components for RC cars and aircraft, brackets, fixtures, protective covers, or robust prototypes.

The Cyan shade gives prints a modern technical look and high visibility – great for distinguishing part versions, functional groups, and for prototypes where specific components need to be easily recognized.

Key Features

• High-toughness PLA – mechanical resistance and impact absorption capacity at the level of ABS.
• Up to 2× stronger layer adhesion than standard PLA – significantly higher resistance to delamination.
• Resistance to repeated bending – suitable for parts subjected to cyclic stress.
• Easy printing like regular PLA – low warping, good layer adhesion, and excellent surface finish.
• Optimized for Bambu Lab printers – full compatibility with all Bambu Lab models and AMS systems.
• Diameter 1.75 mm ± 0.03 mm – high dimensional accuracy for stable filament feeding.
• Neat winding on the spool – 1 kg of material on a high-quality spool for convenient handling and storage.
• Suitable for high-speed printing – the material is designed for the high printing speeds of FDM printers.

Recommended Use

PLA Tough+ is the ideal choice if standard PLA is too brittle, but you don't want to deal with more demanding materials (ABS, ASA, etc.). Typical applications:

• Functional prototypes and fixtures
• Parts for RC cars, aircraft, and drones
• Holders, grips, mounting brackets, and covers
• Protective frames, bumpers, edge protectors
• Mechanically stressed models and parts for hobby projects

Technical Specifications

Basic Parameters

• Material: PLA Tough+
• Color: Cyan
• Filament diameter: 1.75 mm
• Diameter tolerance: ± 0.03 mm
• Net filament weight: 1 kg
• Winding type: on a spool
• Compatibility: all FDM 3D printers with 1.75 mm diameter, fully compatible with all Bambu Lab printers and AMS systems

Recommended Print Settings (Approximate)

Specific values may vary slightly depending on the printer and environment. Always follow the official profile in Bambu Studio / slicer.

• Nozzle temperature: approx. 220–250 °C
• Bed temperature: approx. 35–65 °C
• Cooling: fan on
• Recommended bed type: textured or smooth PEI, or a special PLA plate with an adhesive layer
• Recommended print speed: up to 300 mm/s (for suitable printers and settings)

Mechanical Properties (Typical Material Values)

• Toughness (Charpy, impact strength XY): ~80.6 kJ/m²
• Toughness (Z, layer adhesion): ~25.9 kJ/m²
• Flexural strength (XY): ~65 MPa
• Flexural modulus (XY): ~2140 MPa
• Heat resistance (HDT at 0.45 MPa): ~61 °C

These values show a significant difference compared to standard PLA, especially in impact toughness and interlayer strength, making PLA Tough+ a suitable material for mechanically stressed parts.

Tips for Printing and Use

• For maximum strength, set a sufficient number of perimeters and higher infill (e.g., 30–50% or more depending on the part type).
• For large and tall models, we recommend a well-leveled bed and a clean first layer to ensure perfect adhesion.
• In the case of complicated shapes and supports, it is advisable to use a special support filament for PLA, which facilitates support removal and improves the surface at contact points.
• Store the filament in a dry environment (sealable boxes, silica gel) to maintain top printing quality.

Summary

Bambu Lab PLA Tough+ Cyan 1kg is an excellent choice for users who want to combine the ease of PLA printing with durability close to technical plastics. Thanks to its high toughness, excellent layer adhesion, and attractive cyan color, it is ideal for functional, stressed, and design-prominent prints.
