Abstract
A system for three-dimensional printing is disclosed. The system comprises: a rotary tray configured to rotate about a vertical axis; a printing head, each having a plurality of separated nozzles; and a controller configured for controlling the inkjet printing head to dispense, during the rotation, droplets of building material in layers, such as to print a three-dimensional object on the tray.
Claims19
A system for three-dimensional printing, comprising:
- a rotary tray configured to rotate about a vertical axis;
- a printing head, having a plurality of separated nozzles and being configured to reciprocally move relative to said tray along a radial direction;
- and
- a controller configured for:
- obtaining a radial position of the printing head, controlling said printing head to dispense, during said rotation, droplets of building material in layers, to print a three-dimensional object on said tray, and to vary a rotation speed of said tray responsively to the radial position of said printing head.

- a controller configured for controlling said inkjet printing head to dispense, during said rotation, droplets of building material in layers, to print a three-dimensional object on said tray;
- and
- a radiation source configured to irradiate said layers, wherein the controller is configured to control the radiation source such that energy at different rates is delivered to locations that are at difference distances from a center of said tray wherein a rate at which energy is delivered decreases with the distance from said axis.
