Energy Density Calculator

Energy density (E):

Laser power (P):

Scan speed (v):

Hatch spacing (h):

Layer thickness (d):

How This Is Calculated

$$ E = \frac{P}{v \cdot h \cdot d} $$ where:

E = Energy density (J/mm³)

P = Laser power (W)

v = Scan speed (mm/s)

h = Hatch spacing (mm)

d = Layer thickness (mm)

Assumptions

The power input remains constant.
The printing speed is uniform.
The layer height remains constant.
Heat losses and efficiency variants are ignored.
