However, lead is classified as a substance harmful to the human body that can cause lead poisoning. Therefore, research on the development of lead-free radiation shielding bodies is being conducted. In this study, the shielding body was manufactured by changing the size, layer, and height of the nozzle, using a 90.7% pure tungsten filament, a 3D printer material, and we compared its performance with existing protection tools. Our findings revealed that the shielding rate of the mixed tungsten filament was higher than that of the existing protective tools, confirming its potency to replace lead as the most protective material in clinical field.<\/jats:p>","DOI":"10.3390\/polym14204301","type":"journal-article","created":{"date-parts":[[2022,10,13]],"date-time":"2022-10-13T22:21:11Z","timestamp":1665699671000},"page":"4301","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Influence of Parameters and Performance Evaluation of 3D-Printed Tungsten Mixed Filament Shields"],"prefix":"10.3390","volume":"14","author":[{"given":"Myeong Seong","family":"Yoon","sequence":"first","affiliation":[{"name":"Department of Emergency Medicine, College of Medicine, Hanyang University, 222-1, Wangsimni-ro, Seongdong-gu, Seoul 04763, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9841-7610","authenticated-orcid":false,"given":"Hui Min","family":"Jang","sequence":"additional","affiliation":[{"name":"Department of Radiological Science, Graduate School, Eulji University, 553, Sanseong-daero, Sujeong-gu, Seongnam 13135, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyung Tae","family":"Kwon","sequence":"additional","affiliation":[{"name":"Department of Radiological Science, Dongnam Health University, 50, Cheoncheon-ro 74beon-gil, Jangan-gu, Suwon 16328, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5","DOI":"10.5830\/CVJA-2021-052","article-title":"Radiation exposure protection: Small things matter","volume":"32","author":"Buys","year":"2021","journal-title":"Cardiovasc.
