| Summary: | It is well known that for additive manufactured parts, mechanical properties are
strongly influenced by the printing process parameters. This paper investigates the effect of the
coupon shape and geometry on the mechanical properties, in particular, tensile strength of parts
manufactured using Ultem® 9085, printed using Stratasys Fortus 900MC. Three different types of
coupon geometry, namely ASTM D638 Type I, Type II and ASTM D3039 are tested according to
the respective standard requirements, and it was that found that there is significant variation in the
tensile strength between the specimens. Subsequently, fracture surface of the 3 different specimens
are then examined under the Scanning Electron Microscope (SEM) to provide potential explanations
for the difference in mechanical strength. |
