Although mould repair proved to be a cost-effective technological solution, the restoration of geometrically complex high carbon steel alloys through laser-based Additive Manufacturing still presents criticalities due to the low material weldability, high material oxygen reactivity, and high residual stresses generated by thermal cycling. This research work aims to analyse the influence of substrate preheating and the building environment on the structural integrity of steel specimens exhibiting 0.85 % carbon content and implementing geometrical features which are generally critical to restore by laser-based processes since they behave as thermal stress concentration.

While numerical or experimental approaches alone can be significantly resource intensive, data-driven approaches such as machine learning (ML) have the potential to be more practical. However, the generalizability of ML models currently reported in literature is unclear; few ML models can predict reliably outside of their training domain. This study addresses these challenges by (i) demonstrating a downskin surface roughness classification model, trained on the largest reported dataset for downskin roughness (<span><math><mo>∼</mo></math></span>400 downskin specimens spanning five builds and two ferrous alloys) and (ii) conducting a thorough investigation of the model’s generalizability. Additionally, this study highlights critical issues such as data imbalance, generalization to unseen data, and the importance of rigorous evaluation. By implementing robust ML practices, we focused on model performance across different training and evaluation domains. Our findings indicate satisfactory performance when using the more conservative balanced accuracy metric, achieving about 95% inter-domain and 83% intra-domain accuracy. Although there is still room for improvement, these results demonstrate a significant reduction in the risk of overfitting, thereby enhancing the classifier’s generalizability. This work underscores the importance of methodological rigor in machine learning applications, advocating for greater attention to data treatment and evaluation strategies. This approach may ultimately lead to more effective and usable ML models.

Although many publications show a reduced process dynamic and an enlargement of the process window for dense components using non-Gaussian beam profiles, a generally valid correlation between the energy input - in terms of the beam shape and the process parameters - and the melting mode is lacking. Consequently, intensive experimental work is required to qualify process parameters for alternative beam profiles. The present work aims to reduce this experimental effort for the parameter qualification of alternative beam profiles by estimating the melting modes based on dimensionless parameters. For this purpose, a simple heat conduction model is applied to a new database of melt track widths and depths generated with various ring-shaped beam profiles with different spot sizes. The approach shows a correlation between the dimensionless enthalpy and the melt track depth and width if the 2<sup>nd</sup> moment method is used to determine the spot size of the laser beam profiles. Finally, introducing a maximum dimensionless enthalpy considering the peak intensity of the beam profile used enables the estimation of the melting mode. Regardless of the beam profile, the transition from conduction mode to keyhole mode occurs between maximum dimensionless enthalpies of 6.25 ± 0.85 and 8.65 ± 0.30.</div></div>","PeriodicalId":34573,"journal":{"name":"Advances in Industrial and Manufacturing Engineering","volume":"10 ","pages":"Article 100164"},"PeriodicalIF":3.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143903508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It offers greater design freedom compared to conventional processes and allows the production of complex, lighter geometries with numerous applications in a variety of industries. However, the time and cost required to achieve production readiness present significant challenges to the widespread adoption of new parts development. Success in builds is not reliable until tested, with common issues including distortion, and warpage. The expensive costs of physical iteration to optimize parameters calls for digital simulation to mitigate build failures. This paper presents the successful development of a surrogate model for predicting distortion in a PBF-LB/M metal part. The methodology is grounded on a design of experiments, additive manufacturing tests, finite element modelling playing a critical role, alongside reduced order methods to achieve a surrogate model for improving the additive manufacturing process. The reduced order method for creating the surrogate model is based on tensor decomposition and designed for easy integration into a digital twin, while preserving the underlying physics by retaining the effects of input variables on the final output. The validity of the proposed approach is demonstrated through a benchmark example involving the manufacturing of a metal twin-cantilever part using different laser power, scan speed, and preheating conditions. The twin-cantilever surrogate model developed embeds physics-based simulations and facilitates efficient estimation of deflections.

Changing the process to lower costs necessitates reproducing the same mechanical behaviour and appearance to ensure validation in terms of both style and function.
