The Shadow Factories of the Previous: Distributed Manufacturing for a New Period

Throughout World Conflict 2, the UK confronted provide chain disruptions as extreme and unpredictable as we’re experiencing at this time. To unravel this downside they established the Shadow Scheme, creating one of many first examples of distributed manufacturing.

In accordance with this plan, they constructed dozens of Shadow Factories, each above and underground, protecting them secret from the Axis powers. They transformed farmland, hills and golf programs to manufacturing areas. They opened factories close to areas that had misplaced jobs so that individuals may work. The objective was to unfold their manufacturing out amongst as many amenities as attainable, as far-off as attainable, in order that, if one was incapacitated, they may preserve manufacturing going. In spite of everything, if all Spitfire crankshafts have been produced in a single facility and that facility was destroyed, then that might imply the top of Spitfire manufacturing.

The plan was a powerful success. By 1938 they have been producing their first full plane by a distributed community of amenities unfold throughout the British Empire. The Shadow Factories saved Britain’s manufacturing capability sturdy all through the battle, it doesn’t matter what was thrown at them.

Now, we face an analogous downside: what occurs if a centralized facility is incapacitated by COVID-19, a hurricane or civil unrest?

Distributed Manufacturing

Distributed manufacturing is the method whereby merchandise or components of merchandise are made by many separate companions, unfold out throughout geographically numerous areas, coordinated by a standard communications and data system.

Whereas hub-and-spoke manufacturing won’t ever utterly go away, absolutely counting on just-in-time provide chains is now not reliable. Cargo and distribution of fabric, items and meals can and might be disrupted by this pandemic, local weather change—possibly extra. That is on prime of the environmental harm that worldwide transport and mass-consumption of disposable plastic items causes.

With the rise of digital applied sciences we will construct a distributed community to supply 3D-printed components, circuit boards, laser-cut elements, and so on. extra simply than ever earlier than. By spreading the manufacturing load throughout many various individuals in many various locations, we will flip the tide and make sure that, it doesn’t matter what occurs, we will preserve producing important items. Transport value and complexity can really go down on this system if items are produced nearer to their ultimate place of consumption and if the one factor that’s shipped is uncooked supplies.

High quality Assurance

In all probability probably the most difficult challenge going through distributed manufacturing programs is how to make sure high quality, particularly should you’re opening up your platform to everybody from people to giant firms.

For instance, how do you guarantee a 3D-printed object from a person maker at house is as much as the identical high quality requirements as what comes out of an expert 3D printing home? Or a circuit board, laser-cut half, and so on?

A technique is to make sure that the pc code used to supply every half is unchanged between orders. As soon as the producer is authorized to supply, they can’t use a special set of directions from order to order.

Okay, in order that’s the method, however how do you monitor lot numbers, manufacturing runs, and so on?

If you wish to see how one group is answering these questions and extra, Multimakers has just lately launched a crowdfunding marketing campaign on Kickstarter to lift funds for growing a distributed manufacturing platform and certifying two COVID-19 masks designed from the bottom as much as be produced in a distributed method. Test it out right here by clicking right here.

Conclusion

COVID-19 has disrupted our lifestyle in unprecedented methods. 3D printing and different parts of the maker motion have come to the forefront on this disaster as methods to quickly scale manufacturing capability. However, till now, even these herculean efforts are working at lower than most capability. It’s solely by networking and becoming a member of collectively that we will create a sustainable sample for producing items in an more and more tumultuous world. With distributed manufacturing we will unlock the true energy of digital manufacturing.
