Optimization of Granulate 3D Printer : Focus on cooling

Sammanfattning: The authors, Oskar Geraldsson and Kristoffer Ylander Mikkelsen, together with Svenska Konstruktörsbyrån AB, have customized and optimized a granulate 3D printer. The main goal for the authors is to improve the cooling of the liquid ABS plastic leaving the nozzle to prevent displacement and dislocation during the printing process. Furthermore the printers current state is poor resulting in further work regarding the overall mechanics of the printer such as the power supply, electrical motors and linear guides. The authors have studied existing 3D printers and searched through scientific articlesto get inspiration and knowledge of the mechanical process of the printers aswell as the materials.
