Design and virtual simulation of single-purpose machine
Zlámalík, Jan ; Husák, Michal (referee) ; Kaczmarczyk, Václav (advisor)
This thesis aim is to design a construction of single-purpose machine that will serve as a coffee machine operator. The theoretical part describes the concept of the machine design and its functions. Then the individual components are selected based on the specified requirements. The practical part describes the machine design and simulation in Siemens NX software with Mechatronics Concept Designer package. A software solution for the ESP32 microcontroller is then developed for the real machine. This software solution is ready to be controlled from a hierarchical higher-level system. The function of the machine is tested using a test application developed for this purpose.

Cement Composite for 3D Printing Technology
Lipoldová, Marie ; Hela, Rudolf (referee) ; Bodnárová, Lenka (advisor)
3D printing technology represents a fast-growing industry within many industrial sectors. This bachelor thesis is focused on possibilities of using 3D printing technology in building industry. In the theoretical part there are stated typical technologies and realizations of 3D printing in the field of construction. The thesis also includes a research which is essential for the determination of requirements for cement composites for 3D printing technologies including tests for verification of their properties. The experimental part of the bachelor thesis is focused on testing of various recipes of cementitious composites, especially on the properties of both fresh and hardened composites. Two batches were tested for the suitability of utilisation of waste PET particles.

Computer Vision for Monitoring of 3D Printing
Heinz, Mikuláš ; Hradiš, Michal (referee) ; Smrž, Pavel (advisor)
This thesis deals with the automatic detection of errors that can occur during time-consuming 3D printing. It uses computer vision and artificial intelligence to achieve this. The main result is a system that uses Raspberry Pi and a connected camera to periodically record the printing process and sends the images to the user's computer for detection. On this computer, the image is analysed by a convolutional neural network model and information about found error is sent to the user via a SMTP protocol. The solution also includes a dataset with 385 images of 3D printing errors sorted by type.

Design of the Air conditioning unit for additive robotic fabrication
Mandáková, Adéla ; Chorý, Tomáš (referee) ; Škaroupka, David (advisor)
The design of air conditioning unit is based on combination of the product itself and related architecture. The large-scale 3D printing is becoming more and more popular, that is why this thesis chose additive manufacturing robotic technology for designing the air conditioner. According to analysis the air distribution through perforations is the most convenient one for an indoor unit. An outdoor unit tends to be hidden because of inhomogeneity with the building. To obtain more variant studies for the design a generative process was applied. This method was applied also later on, because additive manufacturing is able to easily change dimension parameters and thus fulfil individual customer requests. Other advantages of robotic printing are the lattice structures that enable perforation manufacturing without waste and the possibility of using generative design methods.

Processing of alloy 2618 using selective laser melting technology
Dokoupil, Filip ; Hutař, Pavel (referee) ; Paloušek, David (advisor)
This diploma thesis deals with finding and verification of appropriate technological parameters of SLM technology for the processing of aluminum alloy 2618. In the theoretical part, an introduction to additive manufacturing of aluminum alloys and general description of processes occurring during SLM production is given. Based on general knowledge were designed different types of testing samples produced by sintering the metallurgical powder using 400 W ytterbium fiber laser, which so far in the literature for aluminum alloy 2618 were not described. As the result, the technological parameters dependence on relative density and the detailed overview of the 2618 alloy processing by SLM technology is determined.

Design of the extruder for additive manufacturing of highly-filled thermoplastics
Kočař, Jiří ; Koiš, Jiří (referee) ; Škaroupka, David (advisor)
The diploma thesis is concerned in design and realization of an experimental extruder for high-filled thermoplastic (Polybet) extrusion, which is a part of an assembly attached to the robotic arm. The result of the work is a device, that is be able to additively and continuously apply layers of Polybet. The s worm threaded extruder with modified parameters is designed with the ability to extrude the thermoplastic melt with additional fillers (sand, glass). The dimensions and weight of the extruder were minimized within limits of the robotic arm carrying capacity. The design of this thesis is an extruder which is able of large-scale additive printing of Polybet with binders (PET or PP). Another result is a mathematical model of material flow and power consumption, adjusted by results of experiments. The thesis is a research of a new part of additive production, where two types of waste material are used for the construction industry. The thesis examines the influence of fillers on power and flow rate through the extruder.
