PETG V0 is the one-in-the-world UL-certified self-extinguishing PETG filament. It is especially suitable for housings and insulating parts in electronics, due to its self-extinguishing properties. Similar to the regular Prusament PETG, it is a tough material with good thermal resistance.
Recommended nozzle temperature: 230±10°C
Recommended bed temperature: 80±10 °C
Print sheet: Using a powder-coated TXT or satin sheet is highly recommended. Printing on a smooth PEI surface might damage the sheet.
PETG V0 is a unique UL-certified self-extinguishing PETG filament. Similar to the regular Prusament PETG, it is a tough material with good thermal resistance. It has universal use, but is especially suitable for housings and insulating parts in electronics, due to its self-extinguishing properties.
PETG V0 is not prone to warping, so printing large objects isn't a problem. When our Prusament PETG V0 starts burning, it creates a carbonized crust on the surface that prevents the oxygen from getting in and fueling the flame and eventually extinguishes the fire.
We asked the UL to test the flammability of the Prusament PETG V0. The test method was made according to the IEC 60695-11-10 standard and resulted in a class UL94 V0 (for both our colors).
See below the Blue Card that serves as a certificate issued by the UL company. You can read more about the UL certification in the product release.
| Pros | Cons |
|---|---|
| ✔ The one-in-the-world UL-certified self- extinguishing filament | ✖ Hygroscopic material - needs drying before every use |
| ✔ Perfect for plastic parts in electronic appliances | ✖ Worse details than PLA, for example - not suitable for tiny parts |
| ✔ Good high-temperature resistance | ✖ Possibility of stringing |
| ✔ Good chemical resistance | ✖ Poor bridging characteristics |
| ✔ Low shrinking and warping | ✖ Prone to stringing and oozing |
| ✔ High strength and durability | ✖ Cannot be acetone-smoothed like ABS |
| ✔ Not brittle | ✖ Supports are harder to remove |
| ✔ Simple to sand | ✖ Prone to scratches (more than PLA) |
| ✔ Mostly odorless while printing | ✖ Slightly worse mechanical properties than regular PETG |
| ✔ Glossy and smooth surface finish |
This filament needs to be kept as dry as possible, as it's more hygroscopic compared to regular PETG. If you can't keep the filament dry, we suggest drying it for 6 hours at 55 °C before use.
Powder-coated Satin or TXT sheet provides proper adhesion. Clean it with IPA (available at drugstores, for example), which works great not only with Prusament PETG V0 but also with other materials.
Pour a small amount of IPA on a paper towel and use it to clean the surface. To achieve the best results, clean the surface while it’s cold. Keep in mind that higher temperatures will evaporate the alcohol before cleaning the surface. Also, don’t forget that the heatbed preheated for printing Prusament PETG V0 has a high temperature (80 °C) and may burn you if you touch it! Another possibility is cleaning the surface with warm water and a few drops of dish cleaner on a paper towel. You can also use denatured alcohol.
We don’t recommend printing with Prusament PETG V0 on a smooth PEI sheet. This material adheres strongly to the PEI surface and may cause damage to it. This type of damage is not covered by the warranty. If you need to print on a smooth surface, spread a thin layer of paper glue-stick on it.
