A three-dimensional printer adapted to construct three dimensional objects is disclosed. In an exemplary embodiment, the printer includes a first surface adapted to receive a bulk layer of sinterable powder, a polymer such as nylon powder; a radiant energy source, e.g., an incoherent heat source adapted to focus the heat energy to sinter an image from the layer of sinterable powder; and a transfer mechanism adapted to transfer or print the sintered image from the first surface to the object being assembled while fusing the sintered image to the object being assembled. The transfer mechanism is preferably adapted to simultaneously deposit and fuse the sintered image to the object being assembled. The process of generating an image and transferring it to the object being assembled is repeated for each cross section until the assembled object is completed.

A method, system and apparatus for variably controlling the temperature in a selective deposition modeling environment. The temperature of the formed portion of the three-dimensional object is detected. A gas is forced onto a surface of the formed portion of the three-dimensional object. The forced gas has a characteristic, such as temperature and quantity, that is variably controlled based on the detected temperature of the formed portion of the three-dimensional object.

Techniques for printing raster lines in a selective deposition modeling (SDM) system. Raster lines may be printed using different numbers of jets in each group in different passes. Moreover, full and partial head randomization is available. Selected raster lines are printed in one direction, although the print head prints in two directions. Furthermore, raster lines printing may be interlaced, and deposition order may be changed between layers.
