Abstract

By analyzing the path of flame propagation in the flame-retardant test and the position of the filament deposition in the FDM process, six kinds of building directions that may affect the flame resistance performance are analyzed. These building directions are XY, XZ, ZX, YX-45, ZX-45, and XYZ-45. Specimens in these building directions were fabricated and tested according to the 60-second vertical Bunsen Burner test method in CCAR 25. The test results show that specimens with different building directions have various burn lengths. XY and YX-45 had the shortest burn length (best flame resistance performance). On the contrary, XYZ-45 had the longest burn length. The results also show that ULTEM 9085 sheets of 0.8mm thickness in all building directions could pass the civil aviation fire retardant tests.
