Prusament PETG Tungsten 75% is a filament specially designed by Prusa Research for radiation shielding applications, incorporating tungsten powder, a material with high density and unique properties. This reinforced filament not only offers an efficient solution for the creation of X-ray and gamma radiation shielding components but is also ideal for medical, scientific, and industrial applications where advanced and safe protection is needed. Unlike lead, tungsten is hypoallergenic, non-toxic, and does not react with water, making it a safer alternative for users and the environment.

Tungsten, known for its high density of approximately 19 grams per cubic centimeter, is one of the heaviest metals in the periodic table. This material has exceptional properties that make it suitable for use as shielding in applications requiring high radiation absorption. Furthermore, as it poses no toxicity risks, it is an ideal option for medical applications, such as the protection of radiopharmaceuticals or radiological diagnostic equipment.

This technical filament not only excels in its radiation protection capabilities but also in its physical characteristics that facilitate its use in FDM 3D printers. Despite its high density, Prusament PETG Tungsten 75% is easy to print, with a fast speed and low odor during printing. However, it is worth noting that due to its high abrasiveness, the use of a hardened steel nozzle is required to prevent damage to the printer.
