Abstract:
1. A selective deposition modeling (SDM) apparatus for forming a three-dimensional object from a build material in a build environment, the apparatus receiving, from a computer, computer data corresponding to layers of the three-dimensional object, the apparatus comprising: a platform configured to support the three-dimensional object in the build environment; a dispensing device comprising an ink jet print head arranged relative to the platform and configured to jet the build material and a support material in the build environment according to the computer data to form the layers of the three-dimensional object from the build material, wherein the build material is a different material than the support material; and one or more non-pulsed continuous-wave (CW) ultraviolet (UV) light-emitting diodes (LEDs) disposed relative to the platform and configured to irradiate the layers with UV radiation that initiates curing of at least the build material, wherein the one or more non-pulsed CW UV LEDs does not substantially produce infrared OR) radiation.
