Abstract
The present research aims to find the best kaolin clay extrusion conditions, suitable for this technology, which would result in an increase in efficiency and quality of the products. Kaolin clay, which is renowned for its thermal stability and compatibility with complex forms, is the main focus of the research because of the growing use in the 3D printing processes worldwide for the manufacturing industries. Research is restricted by the fact that it relates only to kaolin clay and its rheological properties which are specific to the results. The first target is to develop a predictive model that will accurately define the extrusion pressure needed for kaolin clay, using the rheological parameters as a basis. The involved work focuses on the detailed performance of these parameters, such as yield stress, consistency index, and flow index, and their role in extrusion. The methodological approach of the study brings together the experimental determination of kaolin viscosity behavior with the FEA simulations in COMSOL Multiphysics. Sample preparation, performing the rheological measurements, and extruding with a ram extruder are the experimental methods that are used. On the other hand, FEA simulations are meant to recreate the extrusion process and verify experiment results. The results demonstrate that the physical properties of kaolin paste have a strong bearing on its extrusion behavior, and so the rheological properties should be taken into consideration during the printing process so as to optimize the outcome. The study is able to confirm the relation between the experimental results and the computer simulation, all of which confirm the predictive model's accuracy. The topic of the presentations will be the impact on the 3D printing business brought about by these revelations. There is a probability that defective printing can be avoided, and more efficient printing can be achieved through better knowledge of material properties. The study concludes the importance of the exact assessment of rheological parameters and the accurate 3D printing process simulation for bettering of kaolin clay extrusion in 3D printing. Research into the material properties and optimization of the extrusion process should be carried out.
