Real-Time Precision in 3D Concrete Printing: Controlling Layer Morphology via Machine Vision and Learning Algorithms
Autor: João M. Silva, Gabriel Wagner, Rafael Silva, António Morais, João Ribeiro, Sacha Mould, Bruno Figueiredo, João M. Nóbrega, Paulo J. S. Cruz
Publikováno v: Inventions, Vol 9, Iss 4, p 80 (2024)
3D concrete printing (3DCP) requires precise adjustments to parameters to ensure accurate and high-quality prints. However, despite technological advancements, manual intervention still plays a prominent role in this process, leading to errors and in
