Industrial Additive Manufacturing Moves From Last Resort to Planned Production – Interview with Felix Manley of 3D People

Founded in 2017, 3D People is a UK-based industrial 3D printing service focused on polymer components for engineering and production use. Instead of treating additive manufacturing as a bespoke service request, the company frames it as a procurement workflow: users upload CAD data, receive an instant quote, select materials and finishing options, and manage repeat orders via its PartsVault feature—aimed at reducing manual coordination between engineering and purchasing.

Manufacturing is handled entirely in-house, with an emphasis on short lead times and repeatable output for engineers, designers, and manufacturers across sectors such as automotive, OEM supply chains, and film production. For polymer parts, 3D People uses powder-bed systems including Selective Laser Sintering (SLS) and HP Multi Jet Fusion (MJF), typically producing in PA12 nylon. Post-processing options such as vibro polishing and vapor smoothing are offered to adjust surface finish and functional characteristics. The service covers single parts and prototypes as well as scheduled or call-off production, and cites ISO 9001 as its reference point for inspection and delivery consistency.

Interview with Felix Manley

In the interview, Felix Manley, co-founder of 3D People, discusses how industrial additive manufacturing in the UK has moved from last-minute problem solving to a more deliberate production tool, with customers expecting higher consistency and better finishing. He also outlines what still limits scale—especially process stability and post-processing effort—and shares his view on how the market may evolve toward more specialized, application-driven use cases.

How has the demand for industrial 3D printing evolved in the UK in recent years, and what shifts in customer expectations are you seeing as adoption grows?

Demand for industrial 3D printing in the UK has grown steadily, but more importantly, it has matured. A few years ago, many of the larger inquiries we received were reactive—additive manufacturing was used as a last resort when traditional manufacturing timelines collapsed. We’d often see drawings specified for injection molding land in our inbox simply because time had run out.

Today, that has fundamentally changed. We now see production-scale projects designed for PA12 from the outset, with injection molding never part of the conversation. AM isn’t replacing injection molding wholesale, but it has carved out a significant and growing share of polymer manufacturing.

Customer expectations have also sharpened. Many clients come to us after disappointing experiences with low-cost providers or desktop FDM printing and are surprised by what industrial AM can deliver, particularly in surface finish and consistency. Tolerances still require careful expectation-setting, but when designs consider process constraints, AM performs exactly as it should—as a credible, industrial manufacturing method.

Looking back at the past decade of industrial 3D printing, which technical shifts have most enabled true end-use production rather than just prototyping?

The move from prototyping to end-use production wasn’t driven by a single technological breakthrough. It was the result of gradual, cumulative improvements and a mindset shift across the industry.

When we installed our first SLS machine in 2018, PA12 was already the dominant polymer, and it remains so today. While machines like SLS and MJF have become more reliable and refined, the real progress has happened around them. Software has transformed how parts are designed, quoted, nested, and tracked. Workflow tools have reduced friction and human error, while automation has slowly increased trust in repeatability.

Perhaps most importantly, the industry stopped treating additive as experimental. As confidence grew, so did the willingness to use AM for real products. End-use adoption followed not because the technology suddenly changed, but because it became dependable enough to be treated as manufacturing, not prototyping.

What are the most critical technical bottlenecks to scalability in additive manufacturing today, and how are you addressing them?

In powder bed fusion, scalability is ultimately about consistency. As volumes increase, maintaining stable quality becomes more challenging. AM’s flexibility—building hundreds of different parts in a single build—also introduces variability. Changes in packing density alter thermal behavior, affecting cooling rates, internal stress, dimensional accuracy, and surface finish.

The good news is that this is becoming increasingly manageable. Modern machines use dense sensor arrays and predictive software to monitor and correct thermal variation in real time. However, scalability isn’t just a machine problem.

Post-processing remains labor-intensive, and when AM is scaled without local production advantages, the total energy cost per part can still exceed traditional methods. At 3D People, our focus is on tightening every link in the chain—from build consistency and finishing to quality control—so the entire workflow behaves predictably and economically, and supports production at scale without sacrificing additive’s core benefits.

How do you expect industrial 3D printing and the AM market to evolve over the next five to ten years, and how does 3D People fit into that future?

Over the next decade, we expect additive manufacturing to continue fragmenting into specialized, application-driven niches. Progress is likely to come through targeted improvements rather than dramatic leaps—lowering costs, improving efficiency, tightening process control, and simplifying adoption for production use.

Decentralized manufacturing will remain a major theme. AM is already proving its value in spare parts, short runs, and supply chains that prioritize speed and resilience over scale. That trend will only accelerate.

As a service provider, 3D People sits at the intersection of technology and reality. We see what machines can theoretically do, and where friction appears in practice. Our role is to remove that friction through better quoting, production control, finishing, and quality assurance. The strategy is straightforward: keep improving reliability, speed, and cost so additive manufacturing becomes a dependable, everyday production method—not something reserved for niche or emergency use.
