Novel Powder Processing Lab.

Our lab, the Novel Powder Processing Lab at Kyung Hee University, is excited to announce the introduction of a laser-wire directed energy deposition (DED) system. This equipment, manufactured by Meltio in Spain, is the first of its kind to be introduced to a university in Korea(24.12.23.)

While we have been actively utilizing powder-based metal PBF systems, this wire-based equipment offers distinct advantages. We were particularly impressed by its remarkable production speed and user-friendly interface. Moving forward, our research will focus on additive manufacturing of lightweight components using titanium or aluminum alloy wires, as well as exploring post-processing techniques. Additionally, we plan to expand our work to include processes such as joining superalloys and steel, among other advanced metal fabrication applications.

We would like to extend our gratitude to AMSolutions Korea for their invaluable support in the installation and training process.

Our research team has acquired a Nobilta NOB-130 machine from Hosokawamicron through the Korean government’s “Equipment Sharing Program.” This machine can apply forces such as impact, compression, and attrition to powders, thereby modifying their shape or attaching various particles onto the surface of metal powders. Using this equipment, our team plans to produce ODS (Oxide Dispersion Strengthened) metal composite powders and apply them to the PBF (Powder Bed Fusion) process to enhance the mechanical properties of metal alloys and investigate the underlying mechanisms. 

CSCAM's L-PBF machine, AnyX-120, was installed in the NPPL laboratory on 6 October 2023. It is a powder bed fusion type device with a 500W high power laser and will be used exclusively by our research team. It will be used for research on in-situ alloying process during additive manufacturing and additive manufacturing of non-spherical titanium powder. 

세라믹과 나노소재를 합성할 수 있는 신기술이 처음 개발됐다.

KAIST는 홍순형 신소재공학과 교수와 류호진 원자력및양자공학과 교수 공동 연구팀이 고온용 2차원 나노소재인 질화붕소 나노플레이트렛(BNNP)을 세라믹 재료 강화재로 응용하는 기술을 개발했다고 4일 밝혔다.

이 연구는 BNNP로 세라믹 소재의 내충격성을 높일 수 있다는 것을 의미한다. 향후 인공치아, 인공뼈 및 우주항공용 고온 소재 등에 사용될 것으로 기대된다.
