摘要： An apparatus for making a three-dimensional object includes a table, a powdery layer-former that forms a powdery layer on the table, and an optical beam-irradiator that irradiates an optical beam on a predetermined region of the powdery layer to sinter the predetermined region of the powdery layer. A chamber for accommodating the table and the powdery layer-former and a lid for opening and closing an opening defined in the chamber at a location immediately above an optical beam-irradiating range are provided. The three-dimensional object is taken out from the chamber through the opening upon completion of the sintering, and the optical beam-irradiator is disposed at a position deviated from immediately above the optical beam-irradiating range to obliquely irradiate the optical beam on the powdery layer.
