Post-processing waste

Definition

Post-processing waste refers to the material and resources that are discarded or wasted during the finishing steps of 3D printing, such as cleaning, support removal, and surface treatment. This type of waste is significant as it can impact the overall efficiency and sustainability of additive manufacturing processes, making it essential to identify and minimize these losses in material usage.
