TL;DR: The formations of single beads and overlapping multiple beads are modeled and useful not only to predict the bead's shape but also to optimize the three process parameters.
Abstract: Hybrid Layered Manufacturing is a Rapid Manufacturing process in which the metallic object is built in layers using weld deposition. Each layer built through overlapping beads is face milled to remove the scales and scallops and ensure Z-accuracy. The formations of single beads and overlapping multiple beads are modeled in this paper. While the individual bead's geometry is influenced by the size of the filler wire and the speeds of the wire and torch, the step over increment between the consecutive beads additionally comes into the picture for the multiple bead deposition. These models were validated experimentally. They are useful not only to predict the bead's shape but also to optimize the three process parameters.

TL;DR: In this article, the effect of layer thickness on the tensile, yield, impact strength and residual stress of a part was investigated using the hole drill method, and the analysis revealed that when the layer thickness is smaller, the part is higher.
Abstract: Purpose – Mechanical properties such as tensile, yield, impact strengths, and development of residual stresses play an important role intooling applications. The objective of this paper is to investigate the effect of layer thickness – one of the influential process parameters in stereolithography (SL) process, on mechanical properties of SL components.Design/methodology/approach – Test specimens are constructed as per the ASTM standards for different layer thicknesses in SL 5000 machine, using epoxy resin CIBA tool ® SL5530, a high temperature resistant SL material that is suitable for rapid tooling applications. Tensile, yield and impact tests are carried out with suitable equipments. Residual stress is analysed using hole drill method.Findings – The analysis reveals that when the layer thickness is smaller, the strength of the part is higher.Research limitations/implications – Conclusion of this research is drawn based on the analysis of the most widely used three layer thicknesses of 100, 125 and 150 ...
