The goal is to optimize...

... heights (0.06 mm, 0.10 mm and 0.15 mm). Findings The results show that tensile strength and three-point bending strength both increase with the decrease in build speed and the layer height. The artifact selected for dimensional accuracy test shows higher accuracy of the features when 3D printed...

...) and layer height. The existing FDM printer was customized for the present work. Findings Analysis of infrared images has been done to understand discontinuity at a certain range of process parameters. The effect of printing parameters on inter-bonding, width and thickness of the layers has also been...

... process parameter, namely, raster angle, layer height and raster width, have been selected to study their effect on tensile properties. Parts are fabricated as per ASTM D638 Type I standard. Findings It has been observed that the highest tensile strength obtained at 0° raster angle. Lower value...
