AB  - In this study, Polyamide 12 (PA12) powder recycled after selective laser 
      sintering (SLS) was made into filaments for fused deposition modelling (FDM). 
      Compared with fresh PA12, the melt flow rate (MFR) of the recycled PA12 powder 
      decreased by 77%, but the mechanical properties were only slightly reduced. In 
      FDM, the printing speed and building orientation were changed, and the 
      performance of the printed parts was tested. If the printing speed is too fast or 
      too slow, the mechanical properties of the parts will be affected, and there is 
      an optimal speed range. The tensile strength, flexural modulus, and impact 
      strength of a printed test sample made from recycled powder reached 95%, 85%, and 
      87% of an x-direction test sample made from fresh PA12, respectively. For test 
      samples printed from different orientations, the mechanical properties of the 
      test samples printed in the x-direction were the best, while the crystallization 
      performance was the opposite. Scanning electron microscope (SEM) images show that 
      the printed test sample had good compactness and mechanical properties, and the 
      delamination phenomenon was basically not observed.
