Process parameters may be input with multiple values for each to set up parametric simulations. This allows you to study which parameters affect grain size and morphology the most.

Machine - A placeholder for future machine configurations. Defaults to Generic for now.

Laser Beam Diameter (μm) - The width of the laser on the powder or substrate surface defined using the D4σ beam diameter definition. Usually this value is provided by the machine manufacturer. Sometimes called laser spot diameter. Must be between 20 and 140. Defaults to 100 μm.

Laser Power (W) - The power setting for the laser in the machine. Must be between 50 and 700. Defaults to 195 Watts.

Scan Speed (mm/sec) - The speed at which the laser scans, excluding jump speeds and ramp up and down speeds. Must be between 350 and 2500. The default value is 1000 mm/sec.

Baseplate Temperature (°C) - The controlled temperature of the baseplate. Must be between 20 and 500. The default value is 80°C.

Layer Thickness (μm) - The thickness of the powder layer coating that is applied with every pass of the recoater blade. Must be between 10 and 100. The default value is 50 microns.

Hatch Spacing (μm) - The distance between adjacent scan vectors when rastering back and forth with the laser. Hatch spacing should allow for a slight overlap of scan vector tracks such that some of the material re-melts to ensure full coverage of solid material. Must be between 0.06 and 0.2 mm. The default Hatch Spacing is 0.1 mm (100 microns).

Starting Layer Angle (°) - The angle at which the first layer will be scanned. It is measured from the X axis, such that a value of 0° results in scan lines parallel to the X axis. Must be between 0 and 180°. The starting layer angle is commonly set to 57° (default).

Layer Rotation Angle (°) - The angle at which the major scan vector orientation changes from layer to layer. Must be between 0 and 180°. This is commonly 67° (default).
