Universal muzzle device for an assault rifle
Rušar, Filip ; Majzlík, Pavel (referee) ; Vtípil, Jaroslav (advisor)
This diploma thesis deals with the design of a universal muzzle device for the assault rifle. The device is designed to produce Selective Laser Melting. The main objective is the elimination negative effects of gunshot. The paper explores possibilities of using porous structures for this type of equipment. The influence of individual types of porous structures on the flow of gases is monitored. The universal muzzle device itself is optimized using CFD analyzes. The device was made using SLM technology and experimentally verified. His impact on the impact, gun lift, noise and flame elimination was investigated.

Surface heat treatment after 3D FDM print
Břoušek, Lukáš ; Slaný, Martin (referee) ; Zemčík, Oskar (advisor)
The topic of diploma thesis are surface heat treatments after 3D print by method Fused Deposition Modeling. In the introduction is located recherche of the given issue. Further, we describe the construction and process of the 3D printer construction, on which will be printed samples for experiments in the next part of the thesis. The aim is to determine the behavior and changes of surface structures of heat-affected samples from different materials. Furthermore, the suitability of the used methods and the possibility of their use in practice.

Geometry Correction of a Prototype Part using the Reverse Engineering Technology
Smejkal, Martin ; Sedlák, Josef (referee) ; Slaný, Martin (advisor)
This bachelor thesis summarises some modern engineering technologies, namely Reversed Engineering, Rapid Prototyping and Soft-tooling. The Theory chapter describes the mentioned technologies in details and an extra attention is paid to those used in the Experimental chapter. The Experimental chapter summarises steps involved in a prototype part manufacturing. Specifically, in this thesis the method of Reversed Engineering includes 3D scanning followed by smoothing and adjusting of the obtained point cloud in the GOM Inspect V8 software. The final 3D CAD model is obtained in the Catia software. For the Rapid Prototyping the 3D CAD model was 3D printed using the FDM technology. The obtained 3D printed master model was used to prepare a silicone mould that was subsequently used to create an identical part by the method of Soft-tooling. The original part and parts obtained by 3D printing and moulding were compared in the GOM Inspect V8 software by the method of Surface Analysis.

Desing of the carbon cap for the bike's fork
Gallo, Dominik ; Skřivánková, Vendula (referee) ; Košťál, David (advisor)
This bachelor's thesis discusses problems and solutions of design of the carbon crown for the bike's fork. It shows an overview of the possible implementation of the initial design up to final part. The output will be the crown made of carbon composite by mould pressing. For manufacturing the prototype form will be used 3D printing – Fused Deposition Modeling.

Dimensional Analysis of a Prototype Part Produced by Soft-tooling
Matuška, Jan ; Zouhar, Jan (referee) ; Slaný, Martin (advisor)
This thesis aims to survey contemporary methods of Rapid Prototyping technology, their principle, positives and negatives. Further use of these and other methods for production of forms for small series. The importance of these branches is growing up and it seems, that this trend is going to continue. The practical part of this thesis follows up with manufacturing of Soft Tooling cast and its dimensional analysis.

Engineering design of 3D printer
Schoula, Šimon ; Blecha, Radim (referee) ; Bradáč, František (advisor)
The thesis is focused on structural design of machine prototype for 3D print. Used technology is stereolithography. Machine design must be easy to built and low cost. First part of thesis is especially focused on FDM printers, because the design of my printer is more similar to them. Based on systems analysis are defined all parts of printer. Next part of thesis describes SLA technology from which proceed another requirements for machine. Second part contains final structural design of machine including necessary calculations and simulations. Another parts of thesis are focused on control system of printer including software, risk analysis and technical drawings of selected machine parts.
