Property detail

property AdditiveMachine.laser_power: float

Scanning laser power (W).

Valid values are from 50 to 700 Watts.

property AdditiveMachine.scan_speed: float

Laser scanning speed (m/s).

Valid values are from 0.35 to 2.5 m/s.

property AdditiveMachine.heater_temperature: float

Temperature (°C) of the machine build chamber heater.

Valid values are from 20 to 500 °C.

property AdditiveMachine.layer_thickness: float

Thickness (m) of the powder layer deposited with each pass of the recoater blade.

Valid values are from 1e-5 to 1e-4 m (10 to 100 µm).

property AdditiveMachine.beam_diameter: float

Width (m) 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. It is sometimes called the laser spot diameter.

Valid values are from 2e-5 to 1.4e-4 m (20 and 140 µm).

property AdditiveMachine.starting_layer_angle: float

Angle (°) to scan the first layer at.

The angle is measured counterclockwise from the X axis, such that a value of 90° results in scan lines parallel to the Y axis.

Valid values are from 0 to 180°.

property AdditiveMachine.layer_rotation_angle: float

Angle (°) to change the scan vector orientation from layer to layer.

Valid values are from 0 to 180°.

property AdditiveMachine.hatch_spacing: float

Distance (m) between adjacent scan vectors, or hatches, 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.

Valid values are from 6e-5 to 2e-4 m (0.06 and 0.2 mm).

property AdditiveMachine.slicing_stripe_width: float

Width (m) of a stripe, which is a section of scan lines within a layer.

Valid values are from 0.001 to 0.1 m (1 and 100 mm).
