ANALYZING THE ASPECTS RELATED TO THERMAL TRANSFER IN THE ADDITIVE MANUFACTURING PROCESS BY THERMOPLASTICS USING PLA AND RESPECTIVELY ABS FOR EXTRUSION

Abstract

The study carried out aims to determine the way in which the heat transfer occurs from the front part of the orifice of the extrusion nozzle of the thermoplastic material to the component elements of such an assembly. The paper considers the study in the introductory part of the current situation in the specialized literature. The second part is affected by the analysis of their geometric and dimensional structure and the way of their realization and their interconnection. Further, in the analysis, the way in which the discretization of the process of calculating the temperature values ​​is carried out in the simulation program was considered, and last but not least, the way of its evolution. Based on the graphic simulation for the extrusion temperatures considering poly lactic acid (PLA) and respectively acrylonitrile butadiene styrene (ABS) it was possible to highlight that the area where the extruded material in the part of the structure modification has an increasing temperature trend towards the upper part of cooling it.
