68 MMS August 2017 mmsonline.com ADDITIVE INSIGHTS Understanding Industrial 3D Printing users may start doubting their decision to move into AM. They need to keep in mind that subtrac- tively manufactured parts were not designed for additive manufacture, and therefore direct replace- ment of a conventionally made part with an AM part is not likely to yield any cost benefits. In fact, as mentioned, it will likely be more expensive. In many cases, however, the part can be made faster through AM and/or require less tooling. That is main value proposition for additive manufacturing at this stage, and the economics become clearer to users as they shift into production with AM. Design for AM. As much as users might love to jump directly to this most advanced stage of AM, layering the learning from the earlier stages is critical to success here. Knowing the workflow and economics of AM, combined with its process limitations and post-processing challenges, pro- vides the necessary insights for creative users to identify innovations that can only be enabled by AM. It is at this stage that generative design, lattice structures, topology optimization, internal and Learn more about 3D printing for production from Additive M a nu f a ctu r i ng m ag a z i n e.

These AM innovations may be so revolutionary that they lead to disruptions in a company's supply chain or other business units, which might create new opportu- nities for AM innovation. This is the beginning of a virtuous cycle that revolves around, and is enabled by, AM, and it is the reason why people are so excited about additive manufacturing. But, take your time, keep learning, and eventu- ally you will stack all the layers and become an expert in additive manufacturing who can utilize the full potential of the technology.
