Table 2.
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. |
