Bambu Lab PLA Tough+ Gray 1kg – Refill
Bambu Lab PLA Tough+ Gray Refill 1kg is an improved, impact-resistant PLA filament designed for functional parts and prototypes. It offers strength close to ABS, up to 2× better layer adhesion than regular PLA, reliable printing even at higher speeds, and a practical refill package for reusable Bambu Lab spools. Ideal for RC models, covers, mounts, tools, and technical prints where standard PLA cracks. Color: Gray.

Product description
Product Description
Bambu Lab PLA Tough+ Gray 1kg – Refill is a highly durable next-generation PLA filament developed specifically for Bambu Lab 3D printers, but fully usable in other FDM printers with a filament diameter of 1.75 mm.
PLA Tough+ combines the ease of printing of classic PLA with durability and toughness comparable to ABS. This makes it ideal for functional parts that must withstand impact, bending, repeated stress, or drops – where ordinary PLA easily becomes brittle and cracks.
This Refill (without spool) variant is designed for use with reusable Bambu Lab spools. It minimizes plastic waste, saves space and shipping costs, and is fully compatible with the AMS/AMS 2 Pro automatic filament exchange system.
Key Features
- Reinforced PLA with higher toughness – more resistant to impact and fractures than standard PLA.
- Strength close to ABS – suitable for functional and mechanically stressed parts.
- Up to 2× better layer adhesion compared to regular PLA – significantly reduces the risk of delamination.
- Easy to print like PLA – low warping, excellent layer adhesion, smooth surface.
- Recommended printing speed up to 300 mm/s (in Bambu Lab profiles) – suitable for modern high-speed printers.
- Wide printing temperature range – recommended nozzle temperature approx. 220–250 °C, bed 35–65 °C.
- Refill packaging (without spool) – for reusable Bambu Lab spool, smaller ecological footprint.
- Compatibility with all Bambu Lab printers and AMS systems.
- Color: Gray – a universal technical shade suitable for prototypes and final parts.
Recommended Use
Bambu Lab PLA Tough+ Gray is a great choice for:
- Functional prototypes and mechanical parts
- mounts, grips, mounting elements
- electronics covers, cases, lids
- RC models and hobbies
- parts for RC cars, planes, drones
- bumpers, arms, hinges
- Practical home and workshop aids
- organizers, hooks, clips, locks
- fixtures, jigs, light tools
- Education and prototyping
- more robust models and educational aids that withstand frequent handling
Not intended for applications permanently exposed to high temperatures (e.g., in a car in direct sunlight) – temperature resistance remains similar to classic PLA.
Printing Recommendations
Basic Settings
- Filament diameter: 1.75 mm
- Nozzle temperature: approx. 220–250 °C
- Bed temperature: approx. 35–65 °C
- Cooling: on (standard cooling for PLA)
- Recommended printing speed: up to 300 mm/s (suitable profiles in Bambu Studio / slicer)
For best results, we recommend using:
- original "Bambu PLA Tough+" profile in Bambu Studio,
- high-quality print bed (Textured PEI, Smooth PEI, or Cool Plate with separation glue),
- dry filament storage (sealed container with desiccant).
Benefits of Refill Packaging
- Lower environmental impact – less plastic waste thanks to the reusable spool.
- Lower storage and shipping requirements – more compact packaging.
- Full compatibility with Bambu Lab spool system and AMS.
Winding onto the original Bambu Lab refill spool is quick and easy – just place the filament onto the center of the spool, secure it, and feed the end of the string into the guide hole.
