A device and corresponding method for depositing a powder bed on a surface () is provided. The device comprises a deposition module () configured in order to scan the surface while delivering the powder onto the surface. The deposition module has at least one electromagnetic-response probe () capable of analysing a delivered portion () of the powder bed. The invention finds an application in sintering or selective laser melting machines.

Device for depositing a bed of powder on a surface, said device being provided with an electromagnetic-response probe, and corresponding method

A method for manufacturing an object including the steps of forming layers by adding successive layers of material to form the object by selective laser melting (SLM), and inducing plastic deformation and residual stress into solidified material of at least one of the successive layers of material to improve mechanical properties and a fatigue resistance of the object, wherein the plastic deformation and the residual stress are induced by a laser.

Method and device for implementing laser shock peening or warm laser shock peening during selective laser melting
