Abstract: An example method to determine an excess of build material in 3D printing includes providing an amount of build material, spreading the amount of build material to form a layer of build material on a build platform and to leave any excess build material on an excess zone having visible marks thereon and analyzing the marks on the excess zone to determine an excess of build material at the excess zone.
