연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract ▼ AI-Helper 아이콘AI-Helper

In this paper, we analyzed and considered the precision of parts produced by 3D printing methods. For the latch systems applied to the Wingline folding doors, the 3D shape of the door hinge part was printed using FDM and DLP methods. Then, the 3D printed shape was scanned to measure the dimensions a...

제안 방법

  • For comparing the design model’s dimensions and the 3D printed shape of the door hinge part, the design model and scan model of the door hinge part were aligned using Geomagic Control X software. Figs.
  • For the dimensional inspection, the inspection function of Geomagic Control X software was used. The dimensional tolerance was set to ±0.1 mm to perform the 3D comparison analysis of the design model and the scan model, and 2D comparison analysis used the cross-section of the part. Fig.
  • This study 3D printed the 3D shapes of the door hinge part in the door latch system applied to a wing-in-ground (WIG) craft by applying two methods: FDM and DLP. The dimensions of the actual model and scanned shape were measured by scanning the printed shape.
  • This study applied the design model of a door hinge part in the door latch system of the WIG craft in a 3D printer and scanned the door hinge shape printed through the FDM and DLP methods. The dimensional change of the printed shape by design model and method was examined using the inspection software, thereby drawing the following conclusions.
  • This study used an Artec Space Spider 3D Scanner, a non-contact mobile laser scanner from Redmond, to scan the door hinge. This scanner performs the scanning task while moving around the object as if taking a video and obtains automatically-aligned data in real-time at up to seven 3D images per second.
  • This study, for comparative analysis of door hinge parts using the 3D printing method, set the infill density for FDM 3D printing as 100% (the same condition as DLP 3D printing) to proceed with printing because the infill density is 100% due to the characteristic of DLP 3D printing. Fig.

대상 데이터

  • 3D printed materials. For the part output of the FDM printer, a polylactic acid (PLA) filament (diameter 2.85 mm, silver) and polyvinyl alcohol (PVA) water-soluble support material (diameter 2.85 mm) were used. Photocurable resins were used as materials for the DLP 3D printer.
  • In this study, Ultimaker S5, an FDM type printer, and Zbuilder, a DLP type 3D printer, were used to compare 3D printed materials. For the part output of the FDM printer, a polylactic acid (PLA) filament (diameter 2.
