How are 3D Printed Aerospace Parts Manufactured?
Aerospace Components 3D Printing Process
Aerospace components 3D printing process involves several key steps for ensuring production of high-quality parts. Initially, a component’s digital model is made through the use of computer-aided software (CAD). Subsequently, this model is converted into a format that is specific to the 3D printer.
The 3D printer then starts constructing by depositing material layer by layer in line with dimensions described in the digital model once the digital file has been prepared. Some techniques can be used depending on what properties of materials are needed and how they will be used finally like Selective Laser Melting (SLM), Electron Beam Melting (EBM) or Fused Deposition Modeling (FDM).
After printing, the part goes through various post-processing steps to improve its mechanical properties and surface finish. These steps may include heat treatment, polishing, machining, and surface coating.
