The last decade witnessed a vast advancement in several fields of science and technology, including 3D printing. 3D printing is utilized in a wide range of applications, from printing small objects to full-size houses. This research aims to examine thermal neutron attenuation using Acrylonitrile Butadiene Styrene (ABS) filament infused with a thermal neutron absorbent, employing a Monte Carlo simulation toolkit. Several thermal neutron absorbers were tested individually (gadolinium, boron, gold, and cadmium). The simulation results showed a two-centimeter-thick slab infused with boron reduced the total relative dose to one half. Thus, this sample has the potential to be an excellent thermal neutron shielding material. A four-centimeter-thick slab infused with boron registered a neutron relative dose reduction like that of water, which makes the sample a good candidate for water equivalent phantom manufacturing. As for the gadolinium-infused slab, the results indicate that it could be used as a detector cover to discriminate against neutrons in a mixed radiation field. Infusing the ABS slab with gold reduced gamma-ray dose to around 40% of the total relative dose compared to the bare ABS filament. The neutron relative dose remained unchanged for the gold-infused ABS filament. The use of ABS slab infused with cadmium resulted in a steady reduction of the neutron relative dose compared to the bare ABS filament, while the gamma-ray dose remained unchanged. The results for the ABS slab infused with gold and cadmium indicate that these filaments can be used for radiation detection purposes in a mixed neutron-gamma field.

过去十年见证了包括3D打印在内的多个科学和技术领域的巨大进步。从打印小物件到全尺寸房屋，3D打印被广泛应用于各种应用中。这项研究的目的是使用蒙特卡罗模拟工具包，使用注入了热中子吸收剂的丙烯腈-丁二烯-苯乙烯（ABS）灯丝来检查热中子衰减。分别测试了几种热中子吸收器（ga，硼，金和镉）。模拟结果显示，注入硼的两厘米厚的平板将总相对剂量减少了一半。因此，该样品具有成为极好的热中子屏蔽材料的潜力。一块注入了硼的厚4厘米的平板记录了中子相对剂量的减少，例如水的减少，这使得该样品成为水等效幻影生产的良好候选者。至于注入lin的平板，结果表明它可以用作探测器盖，以区分混合辐射场中的中子。与裸露的ABS灯丝相比，向ABS平板中注入金可以将γ射线剂量降低到总相对剂量的40％左右。注入金的ABS灯丝的中子相对剂量保持不变。与裸露的ABS灯丝相比，注入镉的ABS平板的使用可导致中子相对剂量的稳定降低，而γ射线剂量保持不变。注入金和镉的ABS平板的结果表明，这些灯丝可用于混合中子-伽马场中的辐射检测。
