3D PRINTING: WHAT IS IT?
“Process of joining materials to
make objects from 3D model
data, usually layer upon layer”

IMPACT ON AFTER-SALES SERVICE SUPPLY CHAINS
MOTIVATION
 Many slow movers, long lead times, may be expensive
 High inventory levels to ensure quick response
 Many parts discarded at end of life cycle
 Suppose that we have an alternative sourcing option:
 Small batches (e.g., no moulds, low setup costs)
 Short lead times
 Distributed (local) manufacturing
 What would this mean for your supply chain?

 3D printing offers by far the most potential for small
subcomponents (that may not even be present on
the spare part list)
 But: then the impact on after-sales service supply
chains will remain limited in the next 5-10 years
10/3/2018 8
PROPOSITION

 The gains of 3D printing in supply chain
management mainly exist for special cases, like
 remote areas, including temporary fix
 supply disruptions (including end-of-life)
10/3/2018 9
PROPOSITION

 Supply chain managers should be more in the lead
when introducing 3D printing of parts
 Product development tends to focus on
technological superiority rather than supply chain
profitability and thus overlook relevant parts
10/3/2018 10
PROPOSITION

 3D printing of spare parts on demand will remain an
illusion for downtime critical equipment
 Throughput time including postprocessing will
remain too long in the next decades
10/3/2018 11
PROPOSITION

 An important advantage of 3D printing is that it
facilitates printing on location
 No long customer order lead times (transportation,
customs, …) for centralized inventories
10/3/2018 12
PROPOSITION

 The technical challenges of printing parts at remote
locations (and affecting their performance) will limit
the application of AM for spare parts considerably
10/3/2018 13
PROPOSITION

 In most case, it is best to outsource 3D printing of
spare parts to a specialized industrial partner
10/3/2018 14
PROPOSITION

 An unexplored but promising area is to combine 3D
printing of spare parts with predictive maintenance
10/3/2018 15
PROPOSITION

 It would be a huge advantage for after-sales service
supply chains if parts could be produced as one
piece (part consolidation)
 Lower failure rate
 Less complexity (only Line Replaceable Units, no
Shop Replaceable Units)
10/3/2018 16
PROPOSITION

 The added value of 3D printing lies mainly in
improved product design, and less in supply chain
improvements
