.... The process parameters, including layer thickness, nozzle temperature and build platform temperature, were varied. Design/methodology/approach COMSOL Multiphysics software was used to perform numerical simulations of fluid flow and heat transfer for the printed strands. The polymer melt/air interface...

...Dongqing Yang; Jun Xiong; Rong Li Purpose This paper aims to fabricate inclined thin-walled components using positional wire and arc additive manufacturing (WAAM) and investigate the heat transfer characteristics of inclined thin-walled parts via finite element analysis method. Design...

... deposition paths were involved in the finite element (FE) simulations of EBF process by implementing a specially written program. Findings The results showed that the deposition path had a remarkable influence on heat transfer and transient temperature distribution in the scanning process, resulting...

... was done based on the cladding equation with a 2d heat transfer with a distributed heat source see equation (1) (Grong, 1997). This generated an effective thermal diffusivity of the UAM build given as a percentage of aluminum 3003: Equation 1 In equation (1), T is the temperature (K) at the point...

... of SLS involves unsteady state heat transfer and dynamic boundary conditions. It is known that the thermal characteristics of the bulk material, such as thermal conductivity and heat capacity, are temperature dependent. Moreover, during sintering, the thermal conductivity and the density of the powder...

... of its products. The purpose of this paper is to present modeling of the heat transfer process, to understand the sintering phenomena that are experienced by powder particles in the SLS powder bed during the sintering process. With the understanding of sintering process obtained through the theoretical...
