When creating a product with 3D printing, we can set a number of parameters that affect the appearence and properties of the product. One of the adjustable parameters is the printing speed. By changing the printing speed, the viscosity of the material to be extruded also changes, and thus the properties of the product can change. In the final task of this thesis, we studied for the speed range, in which the products, made with 3D printing technology, would have the highest quality.
In theoretical part of the thesis, we studied at how a 3D printer works according to the method of fused filament fabrication, how temperature and print speed affect the viscosity and the principles of operation of a three-point bending test. Using a 3D printer, we produced several samples at different printing speeds, which have been tested with a three-point bending test. Finally, the samples were evaluated on the basis of visual appearance and dimensional deviations, and on the basis of mechanical properties obtained from the bending test.
