Abstract

The noise generated by a small printer that simulates handwriting is noticeable when it operates in a quiet environment. In this study, analytical experiments were conducted prior to upgrading the printer design. The printer head, linear shaft and printer housing were considered as candidate components affecting the noise characteristics and thereby the noise level of the printer. The results obtained from the conducted computer simulations indicate that printer head’s design is a key factor in reducing the overall noise level. Hence, to maintain the stiffness while reducing the mass, a new design for the printer head was implemented. Furthermore, modifications in the printer components resulted in achieving noise reduction.
