Special Issue Information

Dear Colleagues,

Additive Manufacturing (AM) is a transformative advanced manufacturing technology, featuring high design freedom, material efficiency, and personalized fabrication capability. It has become a key driving force for technological upgrading in aerospace, biomedical devices, energy, and other strategic high-end industries, and plays a vital role in promoting the digital and intelligent transformation of modern manufacturing. However, AM involves complex multi-physics coupling and dynamic thermal-mechanical evolution, with obvious instability and randomness in the forming process. Problems such as internal defects, dimensional deviation, and performance inconsistency often occur, which seriously restrict its large-scale and high-reliability application. To tackle these bottlenecks, precise modeling, in situ monitoring, intelligent anomaly detection, and closed-loop control of AM processes are urgently needed.

This Special Issue on “Additive Manufacturing Processes: Modeling, Monitoring, Anomaly Detection and Control” seeks high-quality works focusing on modeling, monitoring and control of AM processes. Topics include, but are not limited to, the following:

  • Mechanism-based and data-driven modeling of AM processes;
  • Sensing systems and data processing algorithms for AM process monitoring and anomaly detection;
  • Closed-loop control systems for AM processes;
  • Applications of artificial intelligence in the above topics.

Tomographic volumetric additive manufacturing (VAM) is an innovative 3D printing technology that polymerizes an entire volume of photopolymer resin simultaneously. VAM enables an increased printing speed and higher output compared with traditional stereolithography, layer-by-layer printing. We explore the operational implications of adopting VAM in an intelligent manufacturing context by considering process planning and production control issues exacerbated by the time bottlenecks introduced in downstream post-processing stages. Discrete Event Simulation (DES) was used to model production flow for two conceptual scenarios: a small-batch low-mix production environment and a high-mix variable-batch production environment. We simulated production, analyzed bottlenecks and tested intervention strategies that may be implemented: (1) increasing the availability of post-processing equipment, (2) modifying the number of available printers and (3) implementing improved workforce scheduling to reassign skilled operators during downtime of certain machines to reduce waiting time. VAM can speed up the creation of the primary part, but post-processing steps such as curing, washing and finishing the produced part might nullify those savings. Through the intervention methods we studied, the overall system utilization rate can be increased. VAM can achieve higher throughput rates in intelligent manufacturing settings only when it is incorporated into intelligent planning systems with high-speed post-processing. We provide some operational considerations in scaling up the VAM manufacturing capability, specifically focusing on planning challenges and gaps in adoption within manufacturing contexts. In this context, we find that coupling data-driven simulation methods with process planning algorithms may further improve workflow in smart manufacturing environments. Full article
