Three dimensional structure producing device and producing method |
摘要 |
An apparatus for making a three-dimensional object includes a powdery layer-forming unit for forming a powdery layer on a table and an optical beam-irradiating unit for irradiating an optical beam on a predetermined region of the powdery layer to sinter the predetermined region. The optical beam-irradiating unit is disposed at a position spaced from immediately above an optical beam-irradiating range to obliquely irradiate the optical beam on the powdery layer. Because fumes generated by irradiating and heating the powdery layer with the optical beam rise towards a position immediately above them, the optical beam is irradiated from the position spaced from immediately above the optical beam-irradiating range, thereby reducing a cloud of the optical beam-irradiating unit that may be caused by the fumes.
