Mechanical design of experimental extruder for 3D printing of industrial clay
 Žižlavský, Vít ; Krčma, Martin (referee) ; Paloušek, David (advisor)
This bachelor‘s thesis deals with possibilities of FDM printing of industrial clay and construction of experimental extruder for 3D printing of this material. The extruder delivers 3D prints of art and design items. There is no facility to print these clays on 2019 market. The main task of this work is to create a design of the extruder. The theoretical part of the thesis deals with summary of modeling clay properties. In the practical part, the parameters of the extruder are determined, the thermodynamic properties of the clay are measured, the forces necessary for extrusion are measured at different temperatures and the piston extruder is designed. The device extrude the preheated material with a screw piston. Axial displacement of the screw is achieved by turning the nut. The device is adapted for quick replacement of the capsule with preheated clay. The resulting extruder is suitable for experimental prints of model clay with different viscosities. Using the extruder, it is possible to test the actual behavior of the modeling clay during printing and to design optimal printing parameters for its more massive use.
