MODELLING THE SYNTHESIS PROCESS OF METAL WIRE PRODUCTS USING THE FDM METHOD

The paper considers creating a mathematical model for the synthesis process of metal wire products using the FDM method; calculates the energy required for the phase transition from solid wire to liquid material. The authors use with certain assumptions the Navier-Stokes equation for incompressible fluid to calculate the average flow velocity of the molten material, which allows determining the total time required to form a material droplet. The paper calculates the movement speed of the feed head nozzle and wire feed rate into the working zone to obtain a material track close to ideal; the change in the movement speed of the feed head nozzle and wire feed rate into the working zone to mitigate printing defects such as material gaps and overhangs.
