Abstract

Additive manufacturing is a relatively new technology that is increasingly used in both manufacturing and research. In the present paper, we discuss the constructive part of an observation system of the additive manufacturing process with the deposition of plasticized material on the printing support surface. The importance of observation of the deposition process is determined both by the chemical composition of the material deposited and by the technological parameters of deposition. From a constructive point of view, it should be noted that existing commercial printing solutions are not provided with such systems to track the submission process. The author of the study turned to specific components from the optical field of endoscope type to visualize the deposition areas, but also to the camera with magnification of up to 500 times with macroscopic visualization of the printed surface. The design of the mechanical ensemble was carried out with the INVENTOR program, the educational version, and the realization of the designed ensemble will be made through the process of fuse deposition material (FDM).
