IMPACT OF 3D PRINTER VIBRATION REDUCTION ON THE QUALITY OF ITS PRINTOUT

Abstract

The authors focused on the study of vibrations of the 3D printer structure caused by the movement of the extruder during the FDM additive manufacturing process. On the basis of the tests, vibrations were passively reduced to improve the dimensions (resolution) of the final products. The vibrations were minimized by modification of the printer structure and the use of additional energy dissipation elements. Correctness of the actions taken was verified by the measuring system. After the modifications, the same series of measurements as in the initial structure were carried out to observe the changes that took place under their influence. On the basis of the tests carried out, the positive effect of reducing the vibration amplitude of the structure by about 50-70 percent was confirmed, which significantly contributed to the improvement of the final product's dimensional parameters.
