We’re launching a brand new Prusament PETG Tungsten 75% for radiation shielding use - Original Prusa 3D Printers

We’ve previously manufactured some cool composite materials and they were a big success: we prepared materials suitable for mechanical use, such as the Prusament PC Blend Carbon Fiber and Prusament PA11 Carbon Fiber. To make the next step, we decided to make a highly advanced metal-filled filament aimed for technical use rather than aesthetic purposes: we’re launching Prusament PETG Tungsten 75%! While this material is primarily designed for a very specific group of users, we believe that its development will intrigue everyone in the 3D printing community. This filament has a lot to offer – its non-reactive, hypoallergenic and non-toxic properties make it ideal for various medical applications. Additionally, its high density is perfect for creating complex radiation-shielding components in an easier and faster way compared to conventional methods. Let’s talk about it in more detail.

Tungsten, also known as Wolfram (chemical symbol W, atomic number 74), is one of the heaviest metals in the periodic table. With its density of about 19 grams per cubic centimeter, it is comparable to gold and it is about 1.7 times denser than lead  (chemical symbol Pb, atomic number 82). Because of its atomic number, tungsten can be used in various applications as x-rays and gamma-ray radiation-shielding material. It is a mostly non-reactive element that does not react with water, oxygen, or with room temperature air. Unlike lead, tungsten is hypoallergenic and non-toxic, which makes it perfectly suitable for medical applications.
