What can you expect?
Prusament PETG V0 is the one-in-the-world UL-certified self-extinguishing PETG filament. Similar to the regular Prusament PETG, it is a tough material with good thermal resistance. Its use is universal but it is especially suitable for housings and insulating parts in electronics, due to its self-extinguishing properties.
Manufactured In-House By Josef Prusa
We were not satisfied with the quality of filaments on the market. So we decided to make our own! Prusa Research is the only 3D printer manufacturer with its own filament production.
Premium-Grade Materials And Thorough Testing
The whole manufacturing process is closely monitored and tested – string diameter, color consistency, and mechanical properties – to make sure that every spool is perfect.
± 0.02 mm Manufacturing Guaranteed Precision
We believe the industry standard of 0.05 mm isn’t sufficient for perfect 3D printing. Instead, we guarantee ±0.02mm precision and highly-consistent colors in our filaments.
High Quality You Can Check Yourself
We are the only manufacturer that gives the option to inspect parameters of every filament spool. Scan a QR code on the spool to see all details online (check the sample spool).

About Prusament PETG V0
The self-extinguishing material has mechanisms that slow down and eventually stop the flame after it starts burning in the first place. 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). Here’s the Blue Card that serves as a certificate issued by the UL company.
We recommend Prusament PETG V0 for hobby use, e.g., for homemade electronic appliances to avoid a potential fire hazard. And it’s also perfect for companies looking for a UL-certified self-extinguishing filament to make products that are as safe as possible and have the proper certification.

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 before use for 6 hours at 55 °C.
Powder-coated Satin or TXT sheet provides good adhesion. Clean it with IPA (available in drugstores, for example) which works great not only with Prusament PETG V0 but with other materials too.
Pour a small amount of IPA on a paper towel and use it for cleaning 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.You can find more in-depth printing tips in our article at blog.prusa3d.com and in our Material table.
