On 10/10/2017 The International Scientific Journal of Engineering Research and its Applications in India Published in Issue No. 7, Vol. 10, part II research for lecturer Hind Bassel Ali teaching in the Department of Materials Engineering / University of Technology, the research was titled: Effect of fill density on compressive properties in molten precipitation modeling process The study examined the effect of the filling density of the samples in the molten deposition process. One of the three-dimensional printing techniques was applied to the compressive properties. It is shown that when increasing the fill density which is one of the variables of the molten precipitation modeling process.
