The AM Services Market Is Moving From Printing Parts to Running Production

From Prototype Bureaus to Production Partners

Additive manufacturing services used to be a stepping stone. A company would send a design to a bureau, get a prototype or a small batch, and eventually buy its own printers if the numbers justified it. That model is changing. A new report from AM Research argues that the sector has shifted from additive print services to additive production services, and the tracking tools built for the old world no longer fit the new one.

The Scale of What Is Already Being Printed

The numbers are large enough to matter. AM Research estimates that about 28 million metal parts and 454 million polymer parts were produced by additive processes in 2025. Service providers are a key driver of that volume. Many are no longer selling one-off prototypes; they are running repeat production jobs, managing post-processing, finishing, and quality documentation for customers that may never bring the work in-house.

The report notes that print services are becoming a larger and more pivotal part of AM's growth, but that evolution is also making the market more dynamic and complex. The old way of tracking the sector, built back in 2018 around a list of roughly one hundred service bureaus, assumed a fragmented, largely transactional market focused on rapid prototyping and modelling with a few healthcare applications mixed in.

Why the Old Model No Longer Works

In 2018, service providers were often treated as a costly bridge. The theory was that a customer would use a bureau to trial the technology, then buy the same printers internally to scale. The core strategy was transactional. Today, many service providers are acting as production partners, handling finishing, inspection, supply chain logistics, and even design for additive manufacturing advice. The economics have changed, and so has the relationship between provider and customer.

That complexity is why AM Research says it has developed a new market model to track the services sector. The new framework tries to capture how value is created across a wider set of activities: not just the print itself, but the surrounding engineering, materials, quality, and logistics work that turns a printed part into a shippable product.

What This Means for the Industry

For buyers, the shift means additive is becoming a viable outsourcing option for production volumes, not just emergency prototypes. For service providers, it means the competition is moving beyond machine count and price per cubic centimetre to include quality systems, documentation, repeatability, and customer engineering support.

The report does not claim the transition is complete. Plenty of companies still operate as traditional bureaus, and plenty of customers still treat additive as a bridge to in-house production. But the direction is clear: as more real commercial parts are produced by additive processes around the world, the businesses that make those parts are being judged as manufacturers, not as print shops.

AM Research is calling its new model the start of a longer tracking project. If it works, it should give a clearer picture of where the money is actually flowing in additive services: not just who owns the most printers, but who is doing the work that customers are willing to pay a premium for.
