A study of the influence of external factors on the temperature control process of a 3D printer head in FDM technology

The aim of the research presented in this article is to examine the influence of measurable external parameters and non-directly measurable disturbances on the amount of thermal energy emitted by the printer head. The research took into account the influence of the temperature inside the printer chamber and the plasticizing temperature of the material in the head on the amount of electricity consumed when controlling the temperature with the PID algorithm with parameters ensuring the value of the control error below 3 degrees C. The summary presents a generalized level of influence of individual parameters, which gives clear indications which of them should be taken into account and measured during the construction of complex temperature regulators for 3D printers (concerns project no.
