Pure tungsten anti-scatter grid(ASG): X-ray grid for high-end radiography systems
Compared with traditional 2D molybdenum or 1D ASG, tungsten 2D ASG has significant advantages. 1. The high density of tungsten enhances the absorption of spilled X-ray scattering, and improves the CT images quality while ensuring the patients safety. 2. The 3D printing technology of the digital manufacturing mode allows more freedom of design and realizes mass production of high-quality pure tungsten gratings.

DMLS Benefits:
With sufficient design freedom, the ASG can adjust the shape of the beam to reduce X-ray scattering and ensure excellent CT imaging quality;
Good heat resistance, can effectively shield radiation;
Improve and simplify the assembly process, increase efficiency and reduce costs;
Digital manufacturing accelerates product manufacturing and technological innovation.

HBD Main Strengths:
With rich experience in tungsten processing capabilities by DMLS technology, HBD has created a unique forming process that can achieve ultra-thin wall, high precision, and high density, which can nearly completely remove impurities and ensure the surface accuracy of printing parts.
Meanwhile, HBD offers design support ( Analyzing the designed parts to determine whether they are suitable for printing, optimization of components & functions)

HBD-100 Features for Printing Pure Tungsten :
1. Forming size: 105*105*100mm; 325*325*400mm (HBD-350)
2. Accuracy: +-0.02mm
3. Wall thickness: 0.1-0.2mm (minimum 0.08-0.1mm)
4. Density: reaches 99%

Currently, 3D printed pure tungsten components are not only applied in medical shields, CT-ray tubes, X-ray tubes, etc., but also in automotive and nuclear energy application etc. Now that HBD has completed the delivery of dozens of machines, the market has verified that all can meet the needs of large-scale production with easy post-processing and greatly improve the competitiveness of users.
