Desigm of the 3D printer for print material with carbon fibers
Chaloupka, Matyáš ; Kočiš, Petr (referee) ; Pavlík, Jan (advisor)
The presented thesis deals with FDM 3D printing method with emphasis on printing carbon fiber reinforced plastic (CFRP). The aim of this thesis is to engineer the FDM 3D printer designed for printing CFRP and to execute the experiment targeted on comparison of CFRP material properties against commonly used 3D printing plastics such as PLA, ABS, PET etc. The device designed in this work has printing area of 200 x 200 mm with maximum height of the object of 200 mm. The printing bed is heated and the whole device is enclosed. There are two kinds of experiments carried out within the thesis. The first one is focused on tensile strength and Young's modulus of selected materials, while the second experiment compares Charpy's impact strength of specimen with different infill percentage on two selected materials, PET and PET filled with chopped carbon fiber.

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.
