This specification establishes the requirements for the production of reliable, repeatable, reproducible aerospace parts by fused filament fabrication with continuous fiber reinforcement. This specification establishes the requirements to approve new machines, processes, and materials. Specifically, this specification covers the constituent material, the configuration of the machine, operating software, machine calibration, build parameters, and acceptance criteria and testing methodology required to create aerospace parts. This specification also defines the user’s responsibility for following the specified requirements.
Rationale: AMS 7104/1 This specification describes the methods of fabricating parts using Continuous Fiber Reinforcement (CFR), Markforged's patented process consisting of traditional FFF printing combined with continuous fiber reinforcement. It will define and discuss critical requirements which have a substantial effect on the print quality and final print part properties.
