3D metal printing
Vrána, Pavel ; Herčík, Tomáš (referee) ; Řiháček, Jan (advisor)
The work presents a literature search of current technologies for 3D metal printing. In the introduction, the individual methods are divided according to the forms of material into powder, wire, and string. The methods using metal powder are SLS, EBM, and DED. Other methods are ADAM, PMD, and WAAM. For each technology are described the principle, printable materials, usage, and example of the product. For methods using electric arc are described possible metal transfers and their limitations.

Composite Bicycle Frame Design
Bartoška, Vojtěch ; Řehák, Kamil (referee) ; Janoušek, Michal (advisor)
This work aims to the design of a carbon fiber bicycle frame with production technology suitable for piece production. The work summarizes the methods of production of composite frames and important parameters that must be respected when designing the frame. A Gravel frame was chosen for the design. The frame was designed for production using stainless steel printed lugs with glued composite tubes. The proposed solution was strength tested. The work also contains a design of a production jig for the construction of bicycle frames.

Workability study 3D metal printing as technology for prototype plastic parts manufacturing
Kovář, Tomáš ; Herčík, Tomáš (referee) ; Sigmund, Marian (advisor)
This bachelor thesis is focused on the feasibility of metallic 3D printing. The 90MnCrV8 tool steel die is time consuming and expensive to manufacture by conventional methods. When considering the use of a die for a maximum of 50 pieces of moldings, it is possible to choose a material other than tool steel. From the offered possibilities of metal 3D printing, 2 suitable methods were selected, namely SLM and WAAM, where the WAAM method appears to be cheaper. Available materials for steel replacement 90MnCrV8 are metal wire G4Si1 for WAAM method and stainless steel X2CrNiMo17-12-2 for the SLM method. After listing all the options and evaluations, it can be seen that the feasibility of metallic 3D printing as a replacement for conventional tool production is possible.
