Product description
Product Description
Bambu Lab PETG Basic Reflex Blue - Refill is a high-quality PETG filament developed specifically for Bambu Lab 3D printers, but also usable in other FDM printers with a filament diameter of 1.75 mm. The improved PETG Basic formula combines PLA-level strength with typical PETG toughness, making it an excellent choice for functional, stressed, and outdoor parts.
The Refill (without spool) variant is wound to be easily mounted on original reusable Bambu Lab spools or compatible printed spools. An integrated RFID chip (when used with an original Bambu Lab spool) allows for automatic material recognition in the Bambu AMS system, so you just need to insert the spool and print without tedious profile setups.
The Reflex Blue (30603) shade is a deep, rich blue color ideal for design models, functional parts, and combinations with other colors in multi-color printing.
Main Features
- PETG Basic Material – balanced ratio of strength, toughness, and ease of printing
- PLA-level strength, but higher toughness – suitable for parts exposed to impacts and mechanical stress
- Improved printability – reduced stringing, less oozing and clumping, smoother print surfaces
- Resistance to water, UV, and temperature changes – ideal for outdoor use and everyday functional parts
- Refill (without spool) – more ecological solution, lower waste volume, compatible with Bambu Lab Reusable Spool
- AMS compatible – ideal for automatic material switching and multi-color/multi-material printing
- Diameter 1.75 mm ± 0.03 mm – high dimensional accuracy for a reliable feeding system
- Spool of 1 kg net filament – suitable even for longer print jobs without the need for replacement
Recommended Use
Bambu Lab PETG Basic Reflex Blue is especially suitable for:
- Functional and stressed parts – holders, brackets, grips, clips, tensioners
- Tools and aids – vises, fixtures, tensioning mechanisms, organizers
- Outdoor models and accessories – flower pots, bottle holders, parts exposed to weather conditions
- Products exposed to water – watering cans, bottles, containers, components for humid environments
- Toys and sports accessories – frisbees, boomerangs, robust gaming elements
Printing Recommendations
To achieve optimal print quality, Bambu recommends:
- Nozzle temperature: approx. 230–260 °C (usually around 240–250 °C depending on printer and model)
- Bed temperature: approx. 65–75 °C
- Print speed: up to 200 mm/s (for Bambu Lab printers with the corresponding profile)
- Bed: a textured or appropriately prepared surface with good adhesion is recommended (e.g., glue stick, suitable adhesive agent)
- Dry filament: PETG is moisture-sensitive – if exposed to humidity above approx. 50% relative humidity for an extended period, the manufacturer recommends drying the filament before printing according to instructions.
By using original Bambu Lab profiles in Bambu Studio or Bambu Handy, you get optimal settings without the need for manual tuning.
