The present invention relates to a three-dimensional printer comprising: a resin storage unit for storing a photo-curable resin; a build plate which is coated with a photo-curable resin supplied from the resin storage unit, is provided so as to be movable up and down, and supports such that the cured resin can be stacked; a light providing means which is arranged in the upper portion of the build plate and radiates light in accordance with a modeling pattern on the build plate; and a control unit for controlling operations of the resin storage unit, the build plate and the light providing means, wherein the light providing means is provided as a projector having a laser light source. Thereby, a model can be printed efficiently and quickly by curing the photo-curable resin, which forms a model, with a laser light source. In addition, efficient photo-curing can be implemented by uniformly maintaining the thickness of the photo-curable resin; printing quality can be improved by uniformly maintaining the temperature of the photo-curable resin; and a model having a uniform color can be printed by preventing sedimentation of pigment by stirring the photo-curable resin. Furthermore, cost saving in printed matter production can be expected by implementing the recovery and circulation of the photo-curing resin. |
