Parametric values for the printhead and binder jetting.

Parameters Value Significance
Desired Saturation 90% This value represents the theoretical void space that exists between powder particles that will be filled with binder
Drop Volume 68.4 pL Amount of binder per droplet. This must be calculated to achieve desired saturation. This is found via measurement.
Build Layer Thickness (Z layer spacing) 50 μm Build bed drops this distance between each layer followed by powder deposition.
X Jet Spacing 254 μm Distance between jets in the print head.
Y Print Speed 150 mm/s Printhead speed in the Y direction, which is calculated by Drop Spacing and Computed Drop Frequency.
Printhead Firing Frequency 2505 Hz Frequency of printhead firing binder jets.
Passes Per Jet Spacing 4 Number of necessary passes to print each layer.
X Drop Spacing 63.5 μm Distance between binder jets in the X direction.
Y Drop Spacing 59.9 μm Distance between binder jet deposition in the Y direction.
