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.

Calvary
VAVERKOVÁ, Jana
The thesis deals with the subject of Christ s journey with the cross. Separate interruptions remind us of the last moment of Jesus suffering on earth. The work begins with the sentencing of Jesus to death and ends with his placing in the tomb. Everything is executed with the technique of slumping glass on plaster forms. The cycle contains fourteen glass reliefs including inscriptions of separate crosses. A possible fixture falls into the interior of a modern church or larger chapel, as well as into the exterior in the likeness of village chapels set up along the so-called The Hill of the Cross. The work is supplemented by a theoretical attachment with thematic description, inspirational sources and technological procedures.
