Additive manufacturing (AM) hardware and software providers tout the design and material freedom of AM. They do this so much that I believe most companies — and the engineers and designers working for them — think of AM as a design tool, not a manufacturing solution. In fact, look at the distribution channels for most AM hardware systems. They are CAD vendors and resellers who market to engineers and designers, not machining experts that cater to job shops or manufacturing and process engineers.While I have touched on this in previous columns (see “Does Manufacturing Need Additive?” and “Is Additive Freeing Designers or Aiding Manufacturing?”), the point became painfully obvious to me a few months ago when I was preparing my talk for the 3D Printing Workshop for Job Shops at the International Manufacturing Technology Show (IMTS) in Chicago in September 2022. This new workshop was targeted specifically at manufacturing professionals and machining experts looking to find ways to improve operations on the shop floor rather than design the complex, organic-shaped, lightweight structures being heralded by others elsewhere in the AM exhibit hall. As I prepared my presentation for IMTS, I realized that none of the examples or case studies that I usually discuss were relevant to the anticipated audience. In fact, the whole point of using AM on the shop floor is different from those using it for product design and development. Granted, consolidating a multi-part assembly with AM may save some time and labor, but topology optimization, customization, conformal cooling, lattice structures, functionally graded materials and the like have little to no meaning to manufacturing professionals and machining experts using 3D printing to support the work of a job shop. It is the engineers and designers that care about that stuff because it helps them meet product requirements in new and better ways. The requirements that manufacturers need to meet are related to cost and lead time, not lightweighting a component to improve fuel economy of a vehicle, for example. As a result, the uses and applications for AM are different on the shop floor than how AM is being sold to most industries.So how can AM help save cost and time on the shop floor? Examples abound; they just aren’t often showcased in stories about AM’s successes, and they certainly don’t go viral on social media. As a result, we miss out on the practical applications and uses of AM that can actually save time and money on the shop floor. For example, AM technology can be used to create any or all of the following, often at less time and cost:As for quantifying the cost and time savings, three examples I used in my talk are:Finally, for those that want to learn more, Additive Manufacturing Media maintains a list of 10 examples of 3D printed tooling while AM hardware providers like FormLabs, Stratasys and MarkForged, along with AM service providers like Javelin, GSC and PrintYourMind, provide examples that will inspire creative ways to use AM to save time and money on the shop floor.
