초록
3D 프린팅 기술이 가장 많이 활용될 수 있는 분야의 하나가 의학분야이다. 3D 프린팅 기술은 최근들어 더욱 상업화되고프린팅에 사용되는 재료 또한 생체친화성, 생분해성 고분자를 이용 가능하게 됨에 따라 생체의료분야에서의 활용성이 점차적으로 높아지고 있는 경향이다. 생체의료분야에서는 수술 모형을 제작하고 절제범위와 시술 후의 형태를 시술 전에 미리 확인하여 시술시간을 단축하고부작용을 최소화하고 있으며 인공 골과 장기를 생산함으로써 이식에 따른 부작용을 감소시키고 있다. 또한 보청기, 의족 등맞춤형 의료 보조용품을 생산하고 있다. 치의학 분야에도 크라운, 덴쳐 등의 보철 수복물 제작, 교정 장치 및 모델 제작, 임플란트 식립이나 외과 수술을 위한 수술용 가이드 제작 등 치과 의료기술을 한 차원 더 높일 수 있을 것으로 전망된다. 그러나 아직은 프린팅 재료(소재), 조형기술, CAD 관련 소프트웨어 기술, 생체안정성과 유효성 검증, 호환성과 표준화 등해결해야 할 과제가 산적해 있있어 앞으로 이에 대한 지속적인 연구, 개발이 이루어져야 할 것으로 사료된다.
Abstract
One of the fields to which the 3D printing technology can be applied is the field of medicine. Recently, the application of 3D printing technology to the bio-medical field has been gradually increasing with the commercializing of the bio-compatible or bio-degradable materials. The technology is currently contributing to the biomedical field by reducing times required for operations or minimizing adverse effects through preoperative identification of post-surgical consequences or model surgery with artificial bones and organs. This technology also enables the production of customized biomedical auxiliary products like hearing aids or artificial legs etc. For the field of dentistry, the 3D printing technology is also expected to elevate the level of dental treatment by making the customized orthodontic models, crown, bridge, inlay, and surgical guides for implant and surgery. However, issues remaining unidentified or incomplete in printing materials, modeling technology, software technology associated with CAD, verification of bio-stability and bio-effectiveness of materials or in compatibility and standardization of the technology are yet to be solved or be clarified for the full-scale application of the 3D printing technology, thus, it seems such issues should be resolved through further studies.
