Printing anti-scatter grids for CT scanners

CT manufacturers require specialized components and materials to achieve high levels of performance in their machines. One of the critical components in CT scanners are anti-scatter grids (ASG) used to absorb scattered radiation and increase image resolution. The material of choice for these components is tungsten because of its resistance against high temperatures (3422°C), its high resistance against wear and the best stopping power against radiation (Density: 19,3 g/cm³). However, due to the difficulty in processing tungsten and the demanding requirements for the use in medical devices, a very precise and reliable manufacturing technology is needed.
