Eight Polyamide and three Polyester filaments were tested with the goal of comparing the mechanical performance of these two groups of materials. Testing was done in sets beginning with tensile testing, creep testing, impact testing, and ending with layer adhesion testing. Poor performing filaments from earlier tests were eliminated in later testing.
Polymaker PLA Pro was included in most of the tests as a reference point to compare the other filaments to.
The results show that Polyester based filaments can be a good alternative to Polyamides, solving the poor stiffness and creep issues of the latter. However, some of the Polyamides performed better than others and may be better than the Polyesters in terms of durability.
