Mobile additive manufacturing (MAM) involves deploying 3D printing in moving vehicles and has recently garnered significant attention from academia industry. However, no prior work integrates MAM with truck-drone delivery systems to support daily operations, despite the benefits supply chain management. This paper fills this gap by integrating these technologies, considering customer time windows optimal sequences. A mixed-integer linear programming model is proposed establish innovative mechanism. Both exact (CPLEX) heuristic (Lagrangian relaxation algorithm) approaches are utilized compared solve model. Computational studies validate solution methods across various problem sizes (small, medium, large), showing superior performance of Lagrangian optimality CPU time. The then applied a case study using algorithm. Results indicate that drone flight range job complexity significantly impact cost on-time delivery. Beyond achieving timely cost-effective satisfaction, system offers insights into resilience, enabling companies enhance service quality reduce inventory dependence through on-demand spare part production via technology.

Multi-robot coordinated wire-arc directed energy deposition (MRC-WA-DED) has proliferated in recent decades, employing asynchronous independent heating sources to deposit material simultaneously. Beyond enhancing efficiency, MRC-WA-DED introduces a synergic effect between the sources, resulting controllable thermal field on component. This research aims investigate if is beneficial for residual stress and distortion reduction how it can be applied enhance quality of MRC-WA-DEDed parts. A finite element model was developed compare thermodynamic response WA-DED when both (CHSs) single source (SHS) are applied. Simulation experiments were carried out clarify influence different coordination strategies fabricated component’s behavior, distribution, conditions. The results indicate that CHSs leads smoother temperature gradient than accomplished by SHS, reducing maximum layer 49.1%. As validated actual depositions, stress, distortion, hardness ten-layer component reduced 6.5%, 11.2%, 18.6%, respectively.
