Learning Objectives By the end of this section, students will be able to: The foundational step of any 3D printing operation is the creation of a digital design file. We covered the full process of design for additive manufacturing in…
Learning Objectives By the end of this section, students will be able to: Additive manufacturing is a small piece of the overall manufacturing and production landscape. Within any manufacturing environment there will be multiple machines that in conjunction with the…
Figure 7.1 The digital thread refers to the data that is associated with and required for the design, materials selection, build planning, build, post-processing, and quality assurance processes in additive manufacturing. The digital thread becomes very complex and may have compatibility issues…
Qualification in additive manufacturing (AM) ensures that machines, facilities, personnel, and feedstock meet stringent requirements for consistent, reliable production. It aligns closely with certification but focuses on production readiness. Qualification involves several levels: Future advancements aim to streamline qualification through…
Learning Objectives By the end of this section, students will be able to: The design, manufacture, and use of AM parts should follow fixed design, fixed (also known as locked down) process and change management protocols used in modern industrial…
Learning Objectives By the end of this section, students will be able to: Everything thus far addressed in this chapter has gotten the AM part to the verge of production. Once a part has been qualified, and the system on…
Learning Objectives By the end of this section, students will be able to: A simple example of the relationship between certification and qualification would be the design of a rope swing. Let’s say that the rope has to withstand a…
Figure 6.1 Qualification involves evaluating a manufacturer’s ability to undertake each step in the part or system creation process. This becomes even more complex when two or more processes are involved in the creation of a part. This hybrid additive manufacturing system…
Certifying a system containing AM parts from engineering materials requires an understanding of the properties of the material as a function of composition, processing, and environmental effects on the part and the material it is made from. As we now…
Learning Objectives By the end of this section, students will be able to: Most of the parts and materials used in the world are made using robust, repeatable processes with minimal post-fabrication inspections. In industries where the consequences of failure…
