The thermal conductivity of non-standard materials for HVAC
Běťák, Karel ; Rubinová, Olga (referee) ; Uher, Pavel (advisor)
The thesis is focused on the determination of the thermal conductivity coefficient on the group of thermoplastics used for 3D printing (PLA, ABS, PETG). The thesis describes the materials used for 3D printing and the design of air conditioning for the grocery store. A stationary method was used for the solution. The heat flux passing through the sample was measured and the thermal conductivity coefficient was calculated. By the chosen method, we determined the coefficient is = 0,11-0,13 W/(m·K). Comparison with the available results of other methods and authors has shown that the resulting coefficient is lower. Based on the data, it is possible to compare the thermal properties of 3D printing materials.

Usage of Modern Technologies for the Design of the Production of Children's Puzzle
Sýkora, Milan ; Sliwková, Petra (referee) ; Sedlák, Josef (advisor)
This thesis offers a novel approach to prototyping of children's puzzle, using Rapid Prototyping. The theory section describes Rapid Prototyping and additionally provides an extensive discussion of a 3D printing method called Fused Deposition Modeling, which was the method used for the toy prototyping described in the practical section. The 3D printed parts were Post-processed and then assembled as the desired product. The technical and economic evaluation of this method is provided in the final discussion.

Electrically conductive surfaces for 3D printed structures
Šomšák, Martin ; Mikulášek, Tomáš (referee) ; Láčík, Jaroslav (advisor)
This thesis describes the technical possibilities of coating various 3D printed structures by different coating methods. Different surface structures have been created on two models for two 3D printing technologies. Antennas on FR4 and PLA substrates were simulated. After adjusting the dimensions of the antennas in the simulations and the results obtained from the simulations, two speckle antennas on PLA substrate were created. To form the antennas, the substrate was coated with copper foil and electrically conductive spray. Subsequently, the antennas were measured, and the results were compared with the simulations.
