This study aims to compare the accuracy offered by 3D Slicer Software in printing end-use parts inside a Fused Deposition Modeling process of Additive Manufacturing. The purpose, in particular, is to investigate the surface quality and the dimensional stability of the manufactured parts comparing the effect of selecting a different 3D Slicer tool among Simplify3D, Cura and Slic3r 3D. With this scope, parts were produced using these process tools while results were analysed in terms of accuracy, production time and consumption of material. Results, graphically and visually presented, show significant differences in the dimensional and surface accuracy with an optimum outcome offered by the Simplify3D as best 3D slicer tool. The Simplify3D slicer has essential advantages in printed end-use parts because creates the 3D models with significantly better accuracy and quality support.
Over the last few year, the metalworking sector has been undergoing rapid and radical transformations driven by global competition and the revision of the production focus that is being moved from mass customization to mass individualization. A results of this is introduction of new manufacturing strategies such as Industry 4.0, a concept that combines cyber-physical systems and promote communication and connectivity. Therefore, this concept changes not only the face of the manufacturing systems but also causes transformation of existing business models and the society as a whole. This paper deals with the recent trends and paradigms in the field of metal forming, resulting from the concept of Industry 4.0 and the modern market challenges. The maim attention is paid on the flexibility of manufacturing systems and recent developments in design of smart forming tools.
In this paper, the microstructural damage evolution of a steel with ferrite-pearlite microstructure (C45E) during the process of cold upsetting was investigated. The development and accumulation of microstructural damage were analyzed at different areas of the samples that were deformed at different strain levels. The scanning electron microscopy (SEM) results showed that various mechanisms of nuclea-tion of microcavities occur during the upsetting process. In quantitative terms, www.videleaf.com microcavities are predominantly generated in perlite colonies due to fracture of cementite lamellae. In addition, the mechanism of decohesion has a significant influence on the development of a macroscopic crack since a high level of microcraks, especially at higher degrees of deformation, was observed on the ferrite/perlite or ferrite/ferrite interface. It was found that the distribution of microcavities along the equatorial plane of the sample is not uniform as the density of microcavities increases with increasing strain level. The influence of stress state, i.e., stress triaxiality on the nucleation and distribution of microcracks, was also analyzed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
