Unexpected Supply Chain Benefits of 3D Printing

Not all products can be, nor should be, 3D printed. 3D printing will never rival the economies of scale found in mass-produced commodities, though the technology is becoming more capable and reliable.

According to Gartner, 47% of supply chain managers plan to use 3D printing in the next two years. This creates five unexpected benefits of bringing 3D printing into supply chain processes. 

Avoid Negative Outsourcing Effects

Businesses have outsourced to other companies for decades because it made economic sense. However, global logistics is becoming riskier and more expensive. Things only get more complex when you add the time required to negotiate with multiple suppliers, and navigate several time zones and different languages in the mix. More fragmented than ever, outsourced supply chains are losing their luster.

There is huge potential for 3D-printed spare part creation, which, according to one DHL report (bit.ly/35VK0Fu), can account for more than 20% of a company’s unused or excess stock. Many automotive manufacturers are required to stock spare parts for seven to 10 years for every vehicle they make. The end-to-end process that 3D printing offers serves as a fully fledged production method, cutting down on excess stock and wait times for parts. 

Simplify Supply Chain Costs and Save Time

Compared to outsourcing, 3D printing typically has a higher ROI, but supply chain simplification provides other savings as well. Three examples of how 3D printing can generate even more ROI include: 

Transport Costs

The logistical nightmare of producing and shipping spare parts from overseas offers an opportunity for easy savings. By simply installing a 3D printer to meet on-demand part manufacture, research suggests companies could save up to 85% on shipping costs.

Wider Profit Margins 

Based on public data sets from the Bureau of Labor Statistics and manufacturing industry economic data, it can be estimated that cost of operating in the manufacturing industry in the United States is $4,258,341 per minute, with a profit margin of only $22,480 each minute. 

3D printing can impact a large industry if it can save time in gained productivity. Although the cost savings for printing one prototype part in-house may not seem significant, each opportunity to save time or money adds up quickly, especially for large-scale manufacturing facilities.

Reduced Labor

Typically, overseas labor rates were cheaper than U.S. rates, so many manufacturers outsourced that cost. 3D printing reduces dependence on this variable because one trained worker can operate a small spare parts production facility at a workstation. This is due to increased printer uptime and reliability, with network-enabled machines controlled via intuitive printer management software.

Create a More Agile Value Chain

Traditional supply chains are not known for their responsiveness and are only getting more complex. By reducing the manufacturing duration and cutting out overseas transportation, 3D printing almost negates lead times. 

Depending on their complexity, most printed parts are produced in hours, not weeks; organizations can easily scale production output with multiple machines to meet demand.

Benefit from 3D Printing’s Unique Product Performance

3D printing offers small-batch manufacturing with a significant advantage: geometric freedom. Traditional production methods, like injection molding, can be restrictive and follow design-for-manufacturing rules. 

With 3D printing, more exotic and efficient geometries can be printed with generative design—leading to improved structural performance, material savings and a shorter design-to-manufacturing cycle.

Differentiate Services with On-Demand Part Production

As digitization fuels the “demand economy,” 3D printing synergizes perfectly with connected manufacturing. This on-demand part production enables greater levels of personalization for finished or almost-finished goods. Parts can be individualized, such as manufacturing tools with ergonomics specific to the worker. 

Essentially, 3D printers can replace your just-in-time inventory. Already a reality, virtual warehouses can send 3D model files digitally to the nearest 3D printer. Logistics companies like DHL and UPS are already using 3D printing to supplement their “end-of-runway” services when specific parts are needed in the fastest time possible.

Not everything should be 3D printed. But with its multiple benefits, 3D printing technology can improve the supply chain in ways that shouldn’t be overlooked.
