1. An automatic powder recycling apparatus for use in a three-dimensional object-forming system to attract and filter powder attached on a surface of a finished product, said automatic powder recycling apparatus comprising:

  • a housing;

    a plurality of isolation elements connected with said housing, wherein a sealed space is defined within said housing through said isolation elements;

    an air-blowing device disposed within said sealed space for removing said powder attached on said surface of said finished product;

    a powder filtering member disposed within said housing for dividing said sealed space into a first receptacle and a second receptacle, wherein said finished product and said air-blowing device are accommodated within said second receptacle;

    a recycling member accommodated within said second receptacle; and

    an air-inhaling device in communication with said first receptacle for allowing said first receptacle to be in a negative pressure state, wherein when said powder on said finished product is removed by said air-blowing device and directed to said powder filtering member by said air-inhaling device, said powder is filtered and blocked by said powder filtering member, wherein when said air-inhaling device is disabled, said powder blocked by said powder filtering member naturally falls down to said recycling member.
