I have been researching recently in metals for aerospace engineering (fatigue application based) related to additive manufacturing. They are being printed with the enormous cost for a very small specimen due to Direct Metal Laser Sintering (DMLS) and other similar techniques. Currently, I am looking for polymers since they are much cheaper to print by using the techniques such as SLS, FDM etc. Could anyone please suggest me few recent polymers being used in additive manufacturing for aerospace applications (based on fatigue performance)???
Polyetheretherketone (PEEK) can be used for aerospace application. https://apiumtec.com/en/3d-printer/
This is FFF 3D printer for PEEK.
You may want to check carbon fiber imbued materials (e.g., Nylon) or there are some printers which can also print kevlar with different plastics (see MarkForge)
