A three-dimensional (3-D) printer comprising: an intermediate transfer surface ; a plurality of development stations (152-158) and a support material development station positioned to electrostatically transfer layers of different materials to said intermediate transfer surface, said different materials comprising build materials and a support material ; a transfer station adjacent said intermediate transfer surface, said transfer station is positioned to receive said layers as said intermediate transfer surface moves past said transfer station; a platen adapted to move relative to said intermediate transfer surface, said intermediate transfer surface being adapted to transfer said layers of said materials combined together to said platen each time said platen contacts one of said layers on said intermediate transfer surface at said transfer station to successively form a freestanding stack of said layers on said platen; a laser fusing station : and a controller being configured to control the actions of the printer components, wherein the laser fusing station is positioned to apply laser light to said combined layers after said combined layers have been transferred from said transfer station to said platen , the controller causing said laser fusing station to selectively apply different energy levels of said laser light to said different build materials to sinter said different build materials differently within said layer, whereby said laser light is not applied to said support material within said combined layers, whereby said laser light does not heat said support material, to leave said support material as a loose, unbound material; and the controller further causing a material removal station to remove said support material as said loose, unbound material to separate said build materials from said support material, and leave a 3-D printed part. an intermediate transfer surface ; a plurality of development stations (152-158) and a support material development station positioned to electrostatically transfer layers of different materials to said intermediate transfer surface, said different materials comprising build materials and a support material ; a transfer station adjacent said intermediate transfer surface, said transfer station is positioned to receive said layers as said intermediate transfer surface moves past said transfer station; a platen adapted to move relative to said intermediate transfer surface, said intermediate transfer surface being adapted to transfer said layers of said materials combined together to said platen each time said platen contacts one of said layers on said intermediate transfer surface at said transfer station to successively form a freestanding stack of said layers on said platen; a laser fusing station : and a controller being configured to control the actions of the printer components, wherein the laser fusing station is positioned to apply laser light to said combined layers after said combined layers have been transferred from said transfer station to said platen , the controller causing said laser fusing station to selectively apply different energy levels of said laser light to said different build materials to sinter said different build materials differently within said layer, whereby said laser light is not applied to said support material within said combined layers, whereby said laser light does not heat said support material, to leave said support material as a loose, unbound material; and the controller further causing a material removal station to remove said support material as said loose, unbound material to separate said build materials from said support material, and leave a 3-D printed part. <EOS>
