3D component control using multi-pass liquid transfer

摘要

According to an embodiment, the 3D printer may include a delivery device and a controller. The controller is configured to access the morphology of the portion of the layer formed of the plurality of build materials and to transfer the droplet selectively onto the build material of the layer during the first pass over the layer based on the accessed morphology Determining a second delivery pattern for a delivery device for selectively delivering droplets onto the build material of the layer during the second pass across the first delivery pattern and the layer to control the characteristics of the portion formed by the portion of the build material of the layer can do. The controller may also control the delivery device to selectively deliver droplets onto the build material of the layer in accordance with the first and second delivery patterns determined during the first pass and the second pass.
