Effect of HIP Process and Subsequent Heat Treatment on Microstructure and Mechanical Properties of Direct Metal Laser Sintered AlSi10Mg Alloy

Ertuğrul, Onur; Öter, Zafer Çağatay; Yılmaz, Mustafa Safa; Şahin, Ezgi; Coşkun, Mert; Tarakçı, Gürkan; Koç, Ebubekir (Emerald, 2020)

Purpose – The purpose of this paper is to evaluate the effect of post process combinations, e.g. hot isostatic pressing (HIP) only, HIP 1 T6 heat treatments, and T6 only, with different aging time, on surface properties, ...

Support Optimization for Overhanging Parts in Direct Metal Laser Sintering

Öter, Zafer Çağatay; Çoşkun, Mert; Akça, Yaşar; Sürmen, Ömer; Yılmaz, Mustafa Safa; Özer, Gökhan; Tarakçı, Gürkan; Khan, Hamaid Mahmood; Koç, Ebubekir (Elsevier, 2019)

The present work focuses mainly on the utilization of different support profiles for overhang structures in EOS M290 Direct Metal Laser Sintering (DMLS) machine. Maraging steel (MS1) parts with large overhangs were ...

Benefits of Laser Beam Based Additive Manufacturing in Die Droduction

Öter, Zafer Çağatay; Coşkun, Mert; Akça, Yaşar; Sürmen, Ömer; Yılmaz, Mustafa Safa; Özer, Gökhan; Tarakçı, Gürkan; Koç, Ebubekir (Elsevier, 2019)

The aim of this study was to benefit from the novel design and production freedom of laser manufacturing in order to alter the existing design concept of extrusion dies and to resolve the limits in die production. A ...

Effect of Building Platform Position on the Surface Quality, Dimensional Accuracy, and Geometrical Precision of Direct Metal Laser Sintering (DMLS) Parts

Öter, Zafer Çağatay; Coşkun, Mert; Koç, Ebubekir (Euro PM 2018 Congress and Exhibition, 2018)

This paper presents the variations of surface roughness and geometrical precision of Direct Metal Laser Sintering (DMLS) parts depending on their positions on the building platform of EOS M290. A distinctive design was ...
