Towards high performance living manufacturing systems - A new convergence between biology and engineering

This paper explores the convergence of biology and manufacturing, proposing that "living manufacturing systems" incorporating bio-inspiration, bio-integration, and bio-intelligence can enhance performance. Four demonstrators in design, cutting fluids, additive manufacturing, and control systems provide early-stage evidence for this hypothesis, but further research and ethical considerations are crucial.

Wire and arc additive manufacturing: Opportunities and challenges to control the quality and accuracy of manufactured parts

Wire and Arc Additive Manufacturing (WAAM) holds great promise for creating large metal parts, but challenges remain in controlling part quality and accuracy, especially geometric features like thin walls and overhangs. This review analyzes how heat management, process planning, and parameter selection influence part quality, dimensional accuracy, and common defects like porosity and humping, proposing future research directions focused on overcoming these limitations and expanding WAAM's geometrical capabilities.

Increasing flexibility and productivity in Industry 4.0 production networks with autonomous mobile robots and smart intralogistics

This paper compares the use of autonomous mobile robots (AMRs) in production networks with traditional conveyor-based lines in process industries. The authors develop an analytical model and conduct a parametric analysis to identify conditions under which AMR networks offer higher throughput, flexibility, and cost advantages, concluding that AMR implementation can be beneficial for high product mix scenarios, particularly with decreasing AMR costs and increased shifts.
