Design of recoating system for processing of two metal powders using 3D Printing
Guráň, Radoslav ; Němeček, Stanislav (referee) ; Koutný, Daniel (advisor)
The thesis deals with the design, construction and testing of two different metal powder coating equipment, which is able to work with SLM 280HL metal 3D printer. Since the field of multimaterial metal printing by selective laser melting (SLM) has not been significantly investigated yet, an overview of existing patents and possible approaches to the solution has been developed. The device has been successfully designed and a series of tests was carried out defining the issue of applying an improved head that uses a nozzle and an eccentric vibration motor. Based on the experiments performed, the coating parameters of the multimaterial layer of FeAm and 316L materials were defined. A control system for the partial process automation was created for the proposed device. The device was implemented in a printer that demonstrated both the ability to apply a single multimaterial layer of at least 50 m thickness, and the ability to produce a 3D multimaterial component comprised of up to 200 layers and containing material change across all axes.

Tool change system for 3D printer
Karniš, Radim ; Arm, Jakub (referee) ; Bradáč, Zdeněk (advisor)
The aim of this thesis is to design and implement a toolchaning system for a 3D printer. As a consequence of such expansion, the printer gains the ability of multimaterial printing and switching between a number of active and passive tools during a single production process. In addition to extensive research of other currently available solutions, this thesis describes the complete mechanical and electrical design process of the device. It also documents the implementation of a functional sample, the creation of software both for the base system and the toolchanger expansion, and the implementation of an associated optical measurement and calibration system.
