Fused Filament Fabrication, Process Specification for
This specification establishes the requirements for the production of reliable, repeatable, reproducible aerospace parts by fused filament fabrication but is not limited to such application. This specification establishes the requirements to approve new machines, processes, and materials. Specifically, this specification covers machine configuration, operating software, machine calibration, machine and build parameters, and testing methodology required to create aerospace parts. This specification also defines the user’s responsibility for following the specified requirements.
This document defines the generic technical requirements, quality assurance provisions, and documentation needed for fused filament fabrication to produce parts capable of service in aerospace. Specifically, this standard will cover environmental controls, equipment configuration, software parameters, material controls, calibrations, and testing methodology. It will define and discuss critical requirements, which have substantial effects on the print quality and final print part properties. No such document currently exists, and such a document is needed to maintain high quality fused filament fabrication produced parts.
