3D Printed Collimators

JJ X-Ray is pleased to share the progress of its innovative project on 3D printed neutron collimators. Since its launch, the project has focused on revolutionizing neutron experiments in big science facilities by developing 2D neutron collimators using advanced 3D printing technology and enriched boron carbide powder.

The project began with the observation that while collimators are essential in almost all neutron experiments, current technology only permits 1D collimation. The initiative aimed to change this by exploring 2D collimation using 3D printed enriched boron carbide (10B4C) powder.

Throughout the project, several significant milestones have been achieved. Methods to test and improve powder quality were established, focusing on the crucial 10B4C to 11B4C ratio and particle size. By sieving the original powder, finer particles were obtained, which resulted in improved print quality with finer features and smoother surfaces.

A major breakthrough came with the successful proof of concept for 3D printing the collimators. The technology’s boundaries were pushed, achieving wall thicknesses as thin as 200 micrometers, depending on the overall structure. Additionally, a process was developed to hot-press leftover material into slits or masks for neutron shielding, ensuring efficient use of resources.

The project’s journey wasn’t without challenges. Issues with raw material supply were encountered when a new batch of supposedly enriched boron carbide powder turned out to be ordinary. It was also discovered that the existing batch contained manganese and iron impurities, which could potentially interfere with experiments.

Despite these setbacks, the project has garnered significant interest from potential customers who are impressed with the initial results. Valuable relationships with manufacturers have been established, and enthusiastic responses for collaborations and prototype purchases have been received.

Looking ahead, the focus is on several key areas to advance the technology further. These include finding new sources of enriched boron carbide, improving the structural integrity of 3D printed parts, and preparing to create customer-designed prototypes. A marketing campaign is also being prepared to showcase the innovation to the world.

As this phase of the project concludes on 2025, JJ X-Ray remains committed to pushing the boundaries of neutron science. While challenges persist, excitement surrounds the potential of the 2D neutron collimation technology and anticipation for its impact on future scientific discoveries.
