Abstract
디지털 기술은 보청기 및 보청기 휘팅에 큰 영향을 가져왔다. 그리고 현재는 보청기 쉘제작에까지 영향을 주고 있으며, 본 연구에서는 전통적인 방법과 CAD/CAM을 이용한 방법의 차이점 및 CAD/CAM방법을 설명한다. 플라스틱 물질에 UV에 경화하는 경화제를 첨가하게 되면, UV레이저를 이용하여 정밀한 조형물을 만들 수 있으며, 이때 컴퓨터를 이용하여 UV 레이저를 제어 하게 된다. 이때 Stereo Lithographic Apparatuses (SLA) 과 Selected Laser Sintering (SLS)이 사용된다.|Digital technology has made a large impact on hearing instrument processing and fitting, and it is now making a large impact on hearing aid shell manufacturing. A comparison of conventional shell-making and the new Computer Aided Design and Manufacturing (CAD/CAM) processes is offered, including a review of the two major methods of CAD/CAM printing: Stereo Lithographic Apparatuses (SLA) and Selected Laser Sintering (SLS). The new CAD/CAM methods offer many benefits. However, dispensing professionals may need to consider the way in which they obtain probe-tube measurements and make shell modifications when using these new shells.
