Description:
This PETG filament from ELEGOO is designed for fast, reliable FDM printing, offering a balance of toughness and easy handling for everyday parts and functional prototypes. With the capacity to support high-speed extrusion up to 600 mm/s according to the manufacturer, it suits projects where quicker print times and good light diffusion are useful, such as housings and illuminated panels.
Key Points
The filament combines improved melt flow with PETG’s natural toughness, which helps produce parts with better impact resistance than typical PLA and lower warping during cooling. It is supplied on a 1 kg cardboard spool that weighs approximately 2.2 lbs, and the material is described as neatly wound to reduce tangles and printing interruptions. Users should dry the filament if it has been stored for some time after unpacking.
Technical Specifications
- Name: ELEGOO Rapid PETG Filament 1.75mm Grey 1KG
- Diameter: 1.75 mm
- Net weight: 1 kg (cardboard spool, approx 2.2 lbs)
- Dimensional accuracy: +/- 0.02 mm
- Recommended maximum speed: up to 600 mm/s (according to the manufacturer)
Usage Recommendations
Begin prints at standard PETG temperatures for your printer and adjust flow and retraction settings to match the faster extrusion capability if you intend to exploit high speeds. For best results with light-transmitting parts, consider slightly thinner wall sections or internal diffusion structures to take advantage of the material’s light transmittance. Additionally, because the spool is mechanically wound and manually inspected, it tends to run smoothly on most filament holders, but keep an eye out for moisture uptake and dry the filament when necessary.
Advantages
This filament offers a compromise between speed and durability, enabling quicker production without abandoning the practical strength expected from PETG. It is compatible with a wide range of FDM machines, including many popular high-speed models, and its reduced shrinkage helps when printing larger or more detailed items. Note that while high-speed printing is supported, actual achievable speeds depend on your specific printer, nozzle and settings, and extreme speeds may require further calibration.
