The research investigates the controlling of the printing quality and the printing defects through the process of the production of paper 3D printed-objects from semi-liquid paste as inputted materials of the cellulose and it’s derivative with other components and water using additive manufacturing technology by using the machine (LUTUM® 3D clay PRINTER) and taking into consideration the typical printing properties that affect haptic printing results.
Cellulose is the world’s most abundant biopolymer and is inherently a low cost and widely available material. Moreover, it is environmentally friendly and easy of recycling and required low energy consumption in manufacturing because of ease of dissolve into water. So the question is how we can be able to produce an object from this cheap material with perfectly desired accuracy and structure integration? That is depending on the raw materials, the mix design, and the process of manufacturing. One of these effects that maniple and dominated the geometrical accuracy of the 3D printed objects in comparing with the wanted geometrical result is the printing characteristics like the printing settings, filament settings, and the printer settings. When performing an object printing with selecting the suitable nozzle diameter, where there are several nozzles and with each nozzle has selective values for the printing characteristics to control the capacities and extruder settings and that will eliminate the defect of not straight lines “Zick zack” of the infill lines in the printed results and give a right compatible balance for the speeds and flow rates to extrude.
