In this study, the third order polynomial regression (PR) and deep neural networks (DNN) were used to perform color characterization from CMYK CIELAB space, based on a dataset consisting of 2016 samples which produced using Stratasys J750 3D printer. Five output variables including CIE XYZ, logarithm CIELAB, spectra reflectance principal components compared for performance printer characterizat...

Abstract 3D printing by means of fused filament fabrication involves extruding and depositing melted material in layers to produce a part. Current requires manual intervention from human operator between prints, leading inefficiency. The focus this study was facilitating the automation additive manufacturing process. Based on suggestions for future works field, extended automated 3D-part remova...

The article discusses the technology of production refractory concrete products using a 3D-printer

This paper introduces a new concept of mirror symmetry, called “anomalous mirror symmetry”, which is physically impossible but can be perceived by human vision systems because of optical illusion. This symmetry is characterized geometrically and a method for creating cylindrical surfaces that create this symmetry is constructed. Examples of solid objects constructed by a 3D printer are also shown.

Introduction: In recent years, the use of magnetic resonance (MR) images in radiation treatment planning has drawn considerable attention. However, although the extent of a tumor can be determined in great detail on MR images, the geometric accuracy of these images is limited by distortions stemming from the inhomogeneity of the static background magnetic field, the nonlineari...

Now a days product development using prototype methods for actual usage is a growing concept in engineering. Present work deals with simulation of Compact Tension specimen to get fracture parameters J – integral and Stress intensity factors of product built by polyjet technology 3D printer additive manufacturing system. FEA simulation is carried out with the help of Abaqus software by simulatin...
