Heat accumulation effect in metal droplet-based 3D printing: Evolution mechanism and elimination Strategy

Uniform morphology and good metallurgical bonding between neighboring droplets are crucial in metal droplet-based 3D printing. However, this technique is usually accompanied by a heat accumulation effect during the printing process, leading to poor forming accuracy and non-uniform microstructure and properties of the formed parts. Since the heat accumulation effect is an intrinsic physical property in metal droplet-based 3D printing technique...
