The objective of this thesis is to build the Michelson interferometer that would be accurate, relatively inexpensive and of such quality that could be used as an additional learning tool in elementary and high schools to deepen the learners’ knowledge of interferometry, optical components and would at the same time present different approaches we took when building this device. We focused on the comparison of two different technologies that are used to make holders for mirrors, lens and laser. We paid particular attention to the price of the chosen technological process, accuracy of the final product and simplicity of the interferometer's final calibration. In terms of price, the interferometer's components made with 3D printing are a bit more expensive. The precision required for the device to work was guaranteed with the components regardless of the technological process. The possibility of adjusting the interference patterns is easier with 3D printed mounts, because they have built-in nuts that enable us to adjust the mirror using a screw. Screw threads are carved in aluminium brackets and can deform if being re-adjusted too many times causing the movement not to be as smooth as with the nut mount.
