Special Issue Information

Dear Colleagues,

This Special Issue focuses on advancements in real-time detection systems within additive manufacturing (AM), offering an in-depth exploration of the tools and technologies necessary to drive this field forward. As AM evolves, real-time detection is becoming increasingly critical for improving process efficiency, product quality, and reducing costs. However, its application remains limited due to challenges such as sensor implementation, data transfer and storage, computational costs, and accuracy. One of the primary barriers is the lack of reliable, real-time data from sensors, which constrains the ability to monitor and analyze processes effectively. Additionally, the large volume of data generated during AM processes presents new challenges in processing and analysis.

Overcoming these challenges is essential to advancing AM, and this Special Issue seeks contributions that address these issues. Topics include real-time sensor implementation, in situ monitoring techniques, real-time data management, anomaly detection, predictive modeling, design rules, measurement techniques, metrology, and uncertainty quantification. Review papers and case studies that explore solutions to these critical problems are also encouraged, as they will help drive AM toward greater adoption and capability in real-time process detection.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

This study investigates the real-time monitoring of 3D printing using an endoscopic camera system integrated directly into the print head. The embedded endoscope enables continuous observation of the area surrounding the extruder, facilitating real-time inspection of the currently printed layers. A convolutional neural network (CNN) is employed to analyse captured images in the direction of print progression, enabling the detection of common defects such as stringing, layer shifting, and inadequate first-layer adhesion. The primary innovation of this work lies in its capacity for online quality assessment and immediate classification of print integrity within predefined thresholds. This system allows for the prompt termination of printing in the case of critical faults or dynamic adjustment of printing parameters in response to minor anomalies. The proposed solution offers a novel pathway for optimising additive manufacturing through real-time feedback on layer formation. Full article
