Hello, we are printing 316L stainless steel on a concept laser 200R SLM machine.

During the first deposited layer there is a poor adhesion and therefore arise delamination.

How we can obtain an apropiate adhesion to the base plate?

We are varying laser power around 150 W, scanning speed of 1000 mm/s, layer thickness of 30 um and hatch spacing of 50 um.

Any advice is welcome.

Attached you will find a printed sample
