Design of shell orthopedic insole fabricated by 3D printing
 Chaloupka, Matyáš ; Koutecký, Tomáš (referee) ; Paloušek, David (advisor)
This bachelor thesis deals with the design of shell orthopedic insole fabricated by 3D printing. The background research is focused on matters of pes planus and on the methods of Rapid Prototyping including most commonly used materials. The structural design is focused on designing a material pattern for this medical instrument and consequently modeling sandwich structure by combining two materials, plastic and softened plastic, which is then made using Rapid Prototyping on Fused Deposition Modeling 3D printer. Rhinoceros© was used for the purpose of making a shell orthopedic insole, especially it’s algorithmic editor tightly integrated with Rhino’s 3D modeling tools, Grasshopper®. Final part was made with sandwich structure by combining PLA plastic and Flex material using Rapid Prototyping.

On the analysis of spring steel machinability after a heat treatment
 Vašíček, František ; Humár, Anton (referee) ; Píška, Miroslav (advisor)
This thesis deals with the machinability spring steel after heat treatment. Brief research is devoted to the machinability of steel with a focus on spring steel, various influences acting on the material and selected types of heat treatment. On the example of deteriorated workability of Disc spring are described methods of material analysis, performace and influences on machinability. By assessment of the results of the analysis were identified possible causes of deterioration of machinability from view of heat treatment – soft annealing. The final part discusses possible corrective actions in the annealing process and proposes a non-destructive method for controlling material structures.
