The example shown here shows the potential for print time
optimization through the use of different nozzle sizes within a component.
The component was printed with the patented 4-fold print head in the "high-speed"
version.
A coarse nozzle with a 2.0 mm nozzle outlet and a finer nozzle with a 0.6 mm outlet were used.
The time required for the infill is impressive:
only 7 minutes with the 2mm nozzle
versus 35 minutes with the 0.6mm nozzle
The visible perimeter/exterior was printed entirely with the fine nozzle (layer height 0.25mm, layer width 0.7mm) for optimal surface quality.
The (not visible) inner filling area was printed in the left half of the component with
the coarse nozzle and in the right half with the fine nozzle.
The degree of filling is 25% in both halves.
Upper cover layers were omitted so that the inner filling structure remains visible.
The printing time can be significantly
reduced with the same surface quality: With the fine nozzle, the printing time for the
filling structure is 35 minutes.
The coarse nozzle allows a volume flow that is up to 500% higher and reduces the printing time of the infill to 7 minutes.
