Abstract

Additive manufacturing (AM) is a process that creates products by layering various materials based on 3D digital data. The most significant feature of this process is its ability to produce complex parts and increase design flexibility. As additive manufacturing becomes recognized as one of the critical production processes in the aviation sector, particularly in Urban Air Mobility (UAM), limitations related to its application of qualification and certification systems have emerged. This paper compared a newly established certification system for additive manufacturing with a pre-existing material qualification system for composite materials, identified key components of additive manufacturing, and proposed solutions to challenges faced by qualification and certification systems.

적층가공은 3차원 디지털 데이터를 기반으로 다양한 소재를 적층하여 제품을 제작하는 공정이다. 이 공정의 가장 큰 장점은 복잡한 부품 생산이 가능하고 제품의 설계 자유도가 높아진다는 것이다. 또한, 항공 분야(UAM)에서 적층가공이 중요한 제작공정 중 하나로 인식되면서 규격승인과 인증체계 적용을 위한 한계점이 대두되고 있다. 본 논문에서는 새로이 구축되어야 할 적층가공 인증체계와 기 구축된 복합소재 인증체계[1]를 비교 연구하고, 적층가공의 구성요소와 규격승인 및 인증체계에서의 문제점을 도출하고 해결 방안을 제안한다.
