TL;DR: A rapid customization design prototype system has been developed and applied to the design of a high-speed train’s bogie to illustrate how to construct a product meta-model and how to conduct configuration design on different layers and variant design for generating new products.

TL;DR: In this paper, a methodology based on a laser vision system was proposed to view the surface appearance on the side face of multi-layer single-pass low-carbon steel parts deposited in GMAW-based additive manufacturing, and a corresponding evaluation method was established to quantify the surface roughness.

TL;DR: In this article, a 3D transient heat transfer model of a circular ten-layer single-pass part was built to investigate the thermal behavior in gas metal arc welding (GMAW) based additive manufacturing.

TL;DR: In this paper, a finite element model is developed to calculate the heat propagation of a circular thin-walled component fabricated in gas metal arc welding based additive manufacturing, and the heat evolution, thermal cycle feature, and temperature gradient in molten pool and deposited layers are revealed.

TL;DR: In this paper, a transient three-dimensional model is developed to investigate the thermal stress evolution and residual stress distribution of parts built in arc additive manufacturing (WAAM), and the residual stresses generated in the substrate and deposited layers are measured by the hole-drilling method to verify the effectiveness of the model.
