Abstract
A process of forming a metal part from a metal powder using a laser to melt the metal powder, where a complex part can be formed in which a support structure is formed from lightly bonding metal powder together without melting so that a support structure can be formed, or melting metal powder to form thin ligaments capable of forming a support layer within the metal powder that can be easily broken away when the metal part is finished. The lightly bonded support layer of metal powder can be formed using a ceramic slurry or controlling the laser power or speed so that the metal powder is not melted but lightly bonded together.
