At first glance, it would appear additive manufacturing will mean the end for service parts supply chains. I came across a PwC study that said 85 percent of parts suppliers “will incorporate 3D printing into their [businesses].” The question is, to what degree?
Do I think 3D printing will have a profound impact on parts planning? Yes, but the technology won’t render service supply chains obsolete, as I’ve heard some people suggest.
Let’s look at this from a hypothetical situation. Suppose you manufacture and service industrial turbines. You have 70 locations at which you store parts.
Now assume you have some sort of service parts inventory optimization capability working on the back end of your ERP. It’s analyzing the following factors to determine where you should stock specific parts, and how many:
What would happen if you threw a 3D printer into the mix? The algorithm would try to identify the location in which the 3D printer’s strategic value would be highest and which parts the machine should print. Making these decisions would involve assessing:
Essentially, the service parts optimization algorithm would identify the location where you would see the highest, most expedient return on investment for your 3D printing capability.
Right now, most companies (at least the ones I’ve spoken with) seem to be in the very early stages of implementing additive manufacturing. They see it as an interesting technology, but they're not rushing toward large-scale implementation.
This aligns with one of PwC's findings: The majority of parts manufacturers (60%) expect they will use 3D printing to manufacture only 1% to 10% of their spare parts in the next five years.
3D printing will play an integral role in parts logistics. However, it will not eliminate supply chains. Rather, additive manufacturing will further increase the importance of sophisticated solutions to optimize and manage service parts networks.
