Abstract
Methods and systems (100) of printing a 3D object (101) comprising: depositing material, layer by layer, via printing heads (72) comprising one or more nozzle arrays; and activating each of said printing heads (72) to dispense a building material (50) at least once within a specified period of time during printing.
Claims19
A three-dimensional (3D) printing system comprising:
- a controller, and
- printing heads comprising one or more nozzle arrays,
- wherein said printing system being configured to form a 3D object by depositing a building material, layer by layer, wherein said controller is configured to activate each of said printing heads to dispense the building material at least once within a specified period of time during said printing,
- wherein said 3D object comprises a bulk region and a surface region, wherein said controller is configured to activate said printing heads to deposit the building material to form a portion of said bulk region according to data provided by a CAD file, and wherein said controller is configured to activate said printing heads to deposit the building material to form another portion of the bulk region without relating to said data.
