Claim 0:
1. A photosintering system comprising:
a photosintering device including a light source and a plurality of proximity sensors; and
a mobile device comprising:
a camera;
a data communication link; and
one or more processors in data communication with the photosintering device over the data communication link, and operable to perform the operations comprising:
obtaining, by one or more processors and using the camera, an image of a sintering area;
generating, by the one or more processors and using the image of the sintering area, a grid of the sintering area including a plurality of sub-areas to be sintered within the sintering area, each sub-area defined by a length and a width, and a respective position within the sintering area; and
for each particular sub-area of the plurality of sub-areas:
determining a respective fractional sintering energy for the particular sub-area;
indicating how to position a photosintering device relative to the particular sub-area;
obtaining, using the plurality of proximity sensors and the camera, current positional information for the photosintering device;
determining that the current positional information indicates that the photosintering device is positioned relative to the particular sub-area in accordance with the indication of how to position the photosintering device;
determining, for the sub-area, a cumulative amount of sintering energy applied to the sub-area by previous exposures using the light source of the photosintering device to one or more other sub-areas of the plurality of sub-areas;
determining an exposure sintering energy to apply to the particular sub-area using a difference between the fractional sintering energy for the particular sub-area and the determined cumulative amount of sintering energy previously exposed to the particular sub-area; and
triggering exposure of the exposure sintering energy by the light source of the photosintering device and to the particular sub-area in accordance with the indication of how to position the photosintering device.
