Mass Production of 3D-Printed Tungsten Anti-Scatter Grids that Improve CT Image Quality
Challenge
- Anti-scatter grids (ASG) are a technically demanding application with regard to wall thickness, positional accuracy, radiation absorption and needing to withstand G forces
- Mass production with consistent quality
- Development of the necessary post processing steps to make the ASGs ready for use in CT equipment
Solution
- Longstanding partnership between Dunlee and EOS takes the complete solution to the next level
- Customized EOS printers, EOS Tungsten W1 and Service
- Unique post processing capabilities developed by Dunlee
Tungsten printing is challenging, particularly when printing a high volume of complex parts with precise specifications. Our customized EOS printers are designed for just this and they will allow us to ramp up production to meet the needs of CT manufacturers who are introducing new products.
