“…Additive manufacturing (AM) has taken giant steps ahead from a fancy 3D prototyping tool to the potential transformative technology for the future across multiple disciplines, including aerospace, automotive, biomedical, heavy metal, jewelry, etc . The future of AM has been appealing because of these diverse factors: ability to (1) fabricate parts of theoretically any shape/complex geometries with improved functionalities; (2) reduce the number of parts required in each component, thereby reducing the assembly time and costs; and (3) produce parts with improved properties . Among the metal AM‐based processes, selective laser melting (SLM) or laser‐based powder bed fusion process (LPBF) is widely used, because of its ability to process a wide spectrum of materials compared with other metal AM‐based processes (like the electron beam melting [EBM], direct energy deposition [DED], etc.)…”

Additive manufacturing (AM) processes are gaining more and more attention due to the interest from all sectors (industries, researchers, and scientists). Selective laser melting (SLM) is one of the AM processes that is widely used because of its ability to process a wide variety of materials. However, by and large, only conventional materials are fabricated using SLM, and there exists a technological gap, where new alloys should be developed suiting the AM processes. This technological gap is briefly reviewed, and possible solutions to bridge the technological gap will be introduced.

“…Bunun yanında dayanımda az miktarda bir azalma gözlemlenmiştir. Sürtünme kaynağının SLE parçaların önemli bir sorunu olan düşük sünekliği de iyileştirebileceği tespit edilmiştir [33]. SLE ile üretilen malzemeler anizotropik özellikler göstermekte bu durum da SLE malzemenin kaynak sonrası mikroyapı ve mekanik özelliklerinde farklılığa sebep olmaktadır [34].…”

Öz Katmanlı imalat teknolojisine olan ilgi son yıllarda artış göstermektedir. Katmanlı imalat tekniği, geleneksel imalat yöntemlerinin aksine malzeme eksiltme değil de, malzeme eklenmesi prensibine dayanmaktadır. Yüksek tasarım serbestliği, artık malzeme oluşmaması, kullanıcıya özel ürünlerin imal edilebilmesi, tasarımdan imalata geçiş süresinin düşük olması, hücresel yapılar ve optimum tasarımlar ile daha hafif ürün elde edilebilmesi katmanlı imalat tekniğinin avantajlarındandır. Bunun yanında katmanlı imalat tekniğinin bir takım dezavantajları da bulunmaktadır. Bunlardan bir tanesi katmanlı imalat ile üretilen ürünlerin boyutlarının sınırlı olmasıdır. Araştırmacılar bu problemi ortadan kaldırmak amacıyla katmanlı imalat tekniği ile üretilen metalik malzemeleri kaynak yöntemiyle birleştirerek çalışmalar yapmaktadır. Bu çalışmada lazer ergitme-sinterleme ve elektron ışını ergitme yöntemleri kullanılarak üretilen malzemelerin kaynak kabiliyetinin araştırıldığı çalışmalar derlenmiştir.

“…Hence, SLM is considered to allow for a considerable reduction in fuel emissions, which confers the process of an outstanding ecological performance making it a green technology for the future [ 30 ]. The SLM process has already made a considerable impact in the manufacturing, automobile, aerospace, pharmaceutical, electronics, and sports sectors [ 31 , 32 ] because of its ability to produce a wide variety of materials (metals, alloys, cermets, composites) without any theoretical restrictions [ 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 ].…”

The laser-based powder bed fusion (LBPF) process or commonly known as selective laser melting (SLM) has made significant progress since its inception. Initially, conventional materials like 316L, Ti6Al4V, and IN-718 were fabricated using the SLM process. However, it was inevitable to explore the possible fabrication of the second most popular structural material after Fe-based alloys/steel, the Al-based alloys by SLM. Al-based alloys exhibit some inherent difficulties due to the following factors: the presence of surface oxide layer, solidification cracking during melt cooling, high reflectivity from the surface, the high thermal conductivity of the metal, poor flowability of the powder, low melting temperature, etc. Researchers have overcome these difficulties to successfully fabricate the different Al-based alloys by SLM. However, there exists no review dealing with the fabrication of different Al-based alloys by SLM, their fabrication issues, microstructure, and their correlation with properties in detail. Hence, the present review attempts to introduce the SLM process followed by a detailed discussion about the processing parameters that form the core of the alloy development process. This is followed by the current research status on the processing of Al-based alloys and microstructure evaluation (including defects, internal stresses, etc.), which are dealt with on the basis of individual Al-based series. The mechanical properties of these alloys are discussed in detail followed by the other important properties like tribological properties, fatigue properties, etc. Lastly, an outlook is given at the end of this review.
