Development of hybrid technology for the production of polymer latice structures
Florián, Vojtěch ; Maňas, Pavel (referee) ; Škaroupka, David (advisor)
This thesis deals with the development of a hybrid technology for the production of polymeric rod structures from PLA filament. The main objective of this technology is to increase the printing productivity by forming some of the rods in BCCXYZ structure without melting them completely. The first step was to conduct basic research on polymer forming. This involved a series of tests, including FEM simulations, printing of individual strut members, and analysis of morphology using X-ray powder diffraction (XRD). The results confirmed the feasibility of polymer forming, which led to further development of hybrid printing technology for BCCXYZ structures. The fabricated structures were subjected to compression loading tests and compared with the results of other printing technologies, including their production costs. In this way, the advantages of the hybrid filament rod structure printing technology were identified. To demonstrate the technology, a mould simulating a fibreglass part was created. This research contributes to the advancement of polymer structure printing and has the potential to improve the efficiency and economic viability of the process in industrial applications.

Software solution for storing data from robotic 3D printing
Žalud, Štěpán ; Kroupa, Jiří (referee) ; Bražina, Jakub (advisor)
This thesis deals with the design of a software solution for storing data from robotic 3D printing. The assignment is based on problems observed in the Voxell company. The theoretical part presents the issue and puts it in context within modern industry. Additionally, it introduces tools used for creating such services at a basic level. This is followed by a system analysis leading to the design of the solution's architecture. The practical part then discusses the selection of the database, the creation of individual services, and the deployment of the application on the Docker platform. Finally, the work is evaluated and a possible future direction of development is outlined.

Design of outdoor furniture from polymer concrete
Petlachová, Alena ; Haltof, Vladimír (referee) ; Krčma, Martin (advisor)
The topic of this thesis is to design a set of garden furniture made by robotic 3D printing technology from the Polybet material. Polybet is a modern material consisting of a binder made from recycled thermoplastics and a filler made from crushed waste glass or other materials. The main challenges of the project are the manufacturability by 3D printing method and the ergonomics of the furniture. Based on a design and technical analysis, the first version has been designed and has been further modified into the final form according to the results of the ergonomic studies. The set consists of two types of benches. First one is bench with a backrest designed for sitting or lying down and the second one is bench without a backrest designed for seating a larger number of people. The bench with a backrest offers the possibility of mirroring the same shape and thus increasing the number of pieces in the set to three. All the pieces are manufacturable and they do meet the basic ergonomic requirements.

Application of industrial robots in 3D print
Krůpa, Jiří ; Vetiška, Jan (referee) ; Bražina, Jakub (advisor)
This bachelor thesis deals with the application of industrial robots in 3D printing, especially FDM technology. The introductory part of the thesis describes the basic types of additive technologies usable for robotic 3D printing. The next chapter describes some unconventional methods of 3D printing, using more than three degrees of freedom. The work also presents a comparison of conventional 3D printers with robotic manipulators and an assessment of the suitability of robots for 3D printing. At the end of the work are the necessary hardware and software peripherals for the modification of the robotic workstation for printing FDM technology. The ABB Robotstudio program was chosen as the software peripheral for the work example, and the procedure for creating the control code is described in the relevant chapter. This work also contains the design of printinghead for FDM technology.

Supportless 3D print by 6-axis robotic arm
Krejčiřík, Petr ; Horák, Zdeněk (referee) ; Škaroupka, David (advisor)
This diploma thesis deals with the solution 3D printing by KUKA robotic arm without realization of supporting structures. The 6-axis KUKA KR 60HA robotic arm allows adjusting 3D printing strategies compared to classical 3D printing concept. The first part of the diploma thesis is about the identification of the current state of knowledge, especially the state of the experimental device for the robotic 3D print. To improve quality of the printed is necessary to modify the printing head and develop the suitable calibration principle. Special printing strategies were designed to rearch the 3D printing overhead volumes without creating support structure. A special alghoritm in the Grasshopper evnironment was developed for generating 3D print trajectory on the body surface. For the quality improvement it is necessary to optimize the process parameters. The final step is experimental 3D printing with the evaluation of surface dimensions, geometric precision and layer coherence in various printing strategies.

SCARA robot advanced program functions
Štípek, Martin ; Burian, František (referee) ; Benešl, Tomáš (advisor)
This thesis is devoted to the description of the used SCARA type of robot, controlled by using devices from the Beckhoff company. In original workstation it is necessary to check all systems and then do commissionig of motor cotrollers for correct working of individual axes. A 3D design is created, which serves as a demonstrative model of a possible workplace. The robot is tuned to optimal motor constants. Interpolation from specified points or using G-code is implemented. At the end, for the system is developed web visualization based on the Server-Client principle.
