PURPOSE: A three-dimensional printer is provided to reduce size of system by arranging a powder feed unit to a slider, while preventing deformation of sample product and achieving uniform distribution of powder. CONSTITUTION: A three-dimensional printer comprises a working unit(110) for production of sample product of three-dimensional shape; a pair of first guide bars(120) installed above the work unit; a slider(130) moving in forward and rearward directions along the pair of first guide bars; a driving unit for moving the slider along the first guide bar; a powder feed unit(210) installed to the slider, and which feeds powder to the surface of the work unit; a smoothing head unit(220) arranged in the vicinity of the powder feed unit, and which smooths powder fed by the powder feed unit; and a binder injection unit(230) arranged in the vicinity of the smoothing head unit, and which moves, along a second guide bar(231), in the direction perpendicular to the advance direction of the slider, and injects binder at the smoothed surface of the work unit.
