Design of support structures for parts made of Inconel 718
Kuhajdik, Matej ; Hutař, Pavel (referee) ; Koutný, Daniel (advisor)
This master thesis deals by the design of support structures for the production of parts made of nickel superalloy IN718 using selective laser melting (SLM). The aim of this work is to design a support structure so that technological problems (excessive deformation of the part due to high residual stresses and insufficient heat dissipation) are eliminated and replace the use of massive volume support, which is inefficient in terms of design and production time, consumed material and postprocessing. Mechanical behaviour of residual stresses of built component, design points of selected support structures (perforated block with pins, BCCZ with perforated contour) and design recommendations were quantified by using thermo-mechanical simulations of production and series of experiments. The functional sample was tested by designing specific support structures for the turbine wheel with subsequent production. The support structure ensured safe, successful production without potential problems and met the requirement to minimize material consumption through effective large-scale perforation of the structure.

Support structures for 3D printing from metallic materials
Hruboš, David ; Vrána, Radek (referee) ; Koutný, Daniel (advisor)
This bachelor’s thesis deals with additive technology selective laser melting, which allows creating 3D objects from metal powder. The support structures are required in this process to dissipate process heat and anchor the part to the base plate. Four new types of support structures were designed in this work. The functionality of the structures was verified and mechanical properties of structures were compared in a strength test.
