3DSP feature generation in the YZ and XY plane
Metal Casting Design and Purchasing
Three dimensional sand printing (3DSP) is the process of selectively bonding sand aggregates together utilizing the same resin systems as those present in modern foundries. Several trials were conducted on printed test geometry to better understand the feature generation capabilities of 3D sand printers. The test geometry consisted of rectangles with through holes. The diameters of the holes tested were 3/8-1/2,3/4 and 1-in. The geometry under investigation was printed in two different orientations, the YZ and XY plane. The circles were evaluated on the accuracy, precision, and roundness. The circles printed in the XY plane experienced a lower amount of deviations when compared to the circles printed in the YZ plane. The improved feature generation in the XY plane was attributed to the greater print head resolution on the X and Y axis compared to the Z axis.
