Pristine high-density bulk disks of MgB with added hexagonal BN (10 wt.%) were prepared using spark plasma sintering. The BN-added samples are machinable by chipping them into desired geometries. Complex shapes of different sizes can also be obtained by the 3D printing of polylactic acid filaments embedded with MgB powder particles (10 wt.%). Our present work aims to assess antimicrobial activity quantified as viable cells (CFU/mL) vs. time of sintered and 3D-printed materials. In vitro antimicrobial tests were performed against the bacterial strains ATCC 25922, ATCC 27853, ATCC 25923, DSM 13590, and ATCC 29212; and the yeast strain ATCC 22019. The antimicrobial effects were found to depend on the tested samples and microbes, with being the most resistant and the most susceptible.
使用火花等离子烧结法制备了添加六方 BN（10wt%）的纯净高密度块状 MgB。添加 BN 的样品可以通过将其切割成所需的形状进行机械加工。通过嵌入 MgB 粉末颗粒（10wt%）的聚乳酸长丝 3D 打印，也可以获得不同尺寸的复杂形状。我们目前的工作旨在评估作为活细胞（CFU/mL）与烧结和 3D 打印材料的时间的定量抗菌活性。针对细菌菌株 ATCC 25922、ATCC 27853、ATCC 25923、DSM 13590 和 ATCC 29212 以及酵母菌株 ATCC 22019 进行了体外抗菌测试。抗菌效果取决于测试样品和微生物，其中 是最具抗性的， 是最敏感的。
