Powder bed fusion (PBF) applies to various metallic materials used in the metal printing process of building a wide range complex parts compared other AM technologies. PBF has several variants such as DMLS (direct laser sintering), EBM (electron beam melting), SHS (selective heat SLM and SLS sintering). For reach its maximum potential, machine learning (ML) algorithms are with suitable achieve goals cost-effectively. Various applications neural networks, including ANNs, CNNs, RNNs, popular techniques KNN, SVM, GP were reviewed, future challenges discussed. Some special-purpose listed follows: GAN, SeDANN, SCNN, K-means, PCA, etc. This review presents evolution, current status, challenges, prospects these technologies terms material, features, parameters, applications, advantages, disadvantages, etc., explain their significance provide an in-depth understanding same.

This paper presents the first comprehensive literature review of deep learning (DL) applications in additive manufacturing (AM). It addresses need for a thorough analysis this rapidly growing yet scattered field, aiming to bring together existing knowledge and encourage further development. Our research questions cover three major areas AM: (i) design AM, (ii) AM modeling, (iii) monitoring control AM. We use step-by-step approach following Preferred Reporting Items Systematic Reviews Meta-Analyses (PRISMA) guidelines select papers from Scopus Web Science databases, aligning with our questions. include only those that implement DL across seven categories - binder jetting, directed energy deposition, material extrusion, powder bed fusion, sheet lamination, vat photopolymerization. reveals trend towards using generative models, such as adversarial networks, also highlights an increasing effort incorporate process physics into models improve modeling reduce data requirements. Additionally, there is interest 3D point cloud monitoring, alongside traditional 1D 2D formats. Finally, summarizes current challenges recommends some promising opportunities domain investigation special focus on generalizing wide range geometry types, managing uncertainties both overcoming limited, imbalanced, noisy issues by incorporating (iv) unveiling potential interpretable

The expansive utility of polymeric 3D-printing technologies and demand for high- performance lightweight structures has prompted the emergence various carbon-reinforced polymer composite filaments. However, detailed characterization processing-microstructure-property relationships these materials is still required to realize their full potential. In this study, acrylonitrile butadiene styrene (ABS) two ABS variants, with either carbon nanotubes (CNT) or 5 wt.% chopped fiber (CF), were designed in a bio-inspired honeycomb geometry. These manufactured by fused filament fabrication (FFF) investigated across range layer thicknesses hexagonal (hex) sizes. Microscopy material cross-sections was conducted evaluate relationship between print parameters porosity. Analyses determined trend reduced porosity lower print-layer heights hex sizes compared larger Mechanical properties evaluated through compression testing, specimens achieving higher compressive yield strength, while CNT-ABS achieved ultimate strength due reduction subsequent strengthening. A decreasing increasing size all supported negative correlation height size. We elucidated potential ABS, CNT-ABS, ABS-5wt.% CF composites novel 3D-printed structures. studies development predictive classification regression supervised machine learning model 0.92 accuracy 0.96 coefficient determination help inform guide design targeted performance.
