To enhance the dimensional accuracy and mechanical properties，and reduce the printing time cost of the parts produced by the fused deposition modeling （FDM） process，the three-dimensional models of the dimensional accuracy and mechanical test samples were designed using Creo Parametric 2.0 software，and then sliced and printed.Combined with orthogonal experiments，the influences of printing temperature，speed and layer thickness on the dimensional accuracy of PLA and PETG-ESD drum-shaped test pieces were studied. The conclusion was drawn that the combination of printing speed of 80 mm/s，printing temperature of 210 ℃ and printing thickness of 0.25 mm resulted in the smallest dimensional error.Under the above combination，tensile and compressive tests were conducted on the mechanical test pieces.The experimental results showed that the honeycomb filling method had the highest tensile strength and breaking force among the three filling methods；when the filling rate increased，the tensile strength and elastic modulus of the test pieces significantly improved；when the wall thickness of the model increased， the tensile strength and elastic modulus of the test pieces also increased.In the compressive test，the PETG-ESD material had a higher strength than PLA.
