KINGROON PETG 1.75 mm filament is also sold in a 10 kg pack, typically containing ten 1 kg spools. It is intended for FDM printing of functional parts, prototypes and brackets. Compared with standard PLA, PETG generally offers greater toughness and heat resistance, while it is usually easier to print than ABS.
A large pack may offer an attractive price per kilogram, especially if you print regularly. Before buying, compare the specific offer with the cost of individual spools. PETG also requires attention to drying and print profile settings.
Nozzle and bed temperature
The recommended nozzle temperature for KINGROON PETG is 230–250 °C. In practice, users often print at 240–245 °C with the bed set to 70–80 °C.
These are starting points, not a universal profile. The right temperature depends on the printer, hotend, speed, color and batch. If layers are not bonding well or there is excessive stringing between parts of the model, use a test print to fine-tune the settings.
Drying before printing
PETG absorbs moisture from the air. Wet filament can crackle or produce bubbles during printing, and the finished print may have a rougher surface and more pronounced stringing. The manufacturer recommends drying KINGROON PETG for approximately 8 hours at 50 °C before use. Several users report better results after drying.
After drying, protect the spool from further moisture during storage. This is particularly important with a 10 kg set, as some of the material may remain unused for a long time.
Strength also depends on layer orientation
According to the KINGROON material data sheet, the PETG has a strength above 50 MPa. This is a material property and should not be treated as the strength of a finished print in every direction.
For a functional part, layer orientation, print temperature, wall count and cooling also matter. A part loaded across its layers can behave differently from the same model oriented so that the load acts mainly in the plane of the layers. Test the specific part in its intended application.
Adhesion and warping
PETG generally warps less than ABS as it cools, which helps when printing larger functional parts. A good first layer is not guaranteed, however: a greasy bed or incorrect Z-offset can cause problems.
On PEI, PETG can adhere too strongly. A release layer is therefore used on some smooth PEI surfaces to help protect the surface when removing the print.
How to fine-tune the profile
Rather than blindly copying someone else's profile, start with a test print and change settings gradually:
- Dry the filament and check the first layer on a clean bed.
- Use a temperature test to choose a suitable nozzle temperature within the recommended range.
- Adjust flow and retraction; retraction helps reduce stringing as the nozzle moves between sections.
- Test the settings on a small functional part and check both the surface and layer bonding.
Bambu printer users can start with a generic PETG profile or a Bambu PETG profile, then adjust it. One printer may work well at 240 °C, while another may give better results at 250 °C.
User experiences and the 10 kg pack
Users who go through tens of kilograms of filament often describe KINGROON as an inexpensive material with good value for money. Experiences are not unanimous, though: there have also been reports of more brittle prints with a particular batch. Results may vary between colors and batches, so it is worth testing a new spool first.
If you are new to PETG, starting with one spool may be more practical. A 10 kg set makes more sense for a print farm, prototyping or larger projects where you will use the material and have suitable storage for it.
For its 1.75 mm PETG, the manufacturer lists approximately 330–340 meters per 1 kg spool. Ten kilograms therefore represents more than three kilometers of filament.
What is PETG suitable for?
KINGROON PETG is suitable for items such as brackets, enclosures, prototypes and workshop components. Compared with standard PLA, it is useful where toughness and greater heat resistance matter. For precise decorative models, PLA may be easier to use because it generally has less tendency to string.

Is KINGROON PETG 10 kg worth it?
For someone who prints many functional parts, knows how to calibrate PETG and can dry the filament, the large pack may be a good choice. The deciding factors are the actual price per kilogram and whether you can use the material and store it dry. If you expect flawless results straight out of the package without adjusting the profile, try a single spool first.
