The equation in question, Volumetric Energy Density, given by the formula Ev = P / e.v.h, where P is the power of laser, "e" the layer thickness, v the scanning speed and h the distance between scans. This equation quantifies the amount of energy per mm3 that is put into the material to be melted.

There are optimal values for Ev, in the case of thicknesses of 0.03 mm the value is around 77 J/mm3 and in the case og 0.06 mm it is around 77 J/mm3. Varying this energy when manufacturing a component will induce defects in the part.

My DOE intends to evaluate which process parameters have the most influence on the formation of residual stresses. In the literature, laser power, scanning speed, layer thickness, distance between scans, temeprature and scanning strategy are the parameters that most contribute to the formation of residual stresses.

Now, if i need values to be generated, but that consider the dependence described by the equation. For example, if i reduce the laser power, i will have to porportionally reduce any other factor in the equation.

Thank for your help.
