K3D expands MetalFab fleet to six systems, surpasses one million metal AM parts produced

Dutch additive manufacturing service bureau K3D has added two Additive Industries MetalFab 300 Flex systems, bringing its total MetalFab fleet to six units across two production sites. The expansion follows K3D surpassing one million metal AM parts produced, a milestone the company reached earlier in 2026. K3D, a subsidiary of baking equipment manufacturer Royal Kaak, operates MetalFab systems capable of processing 316L stainless steel, AlSi10Mg aluminum, and Ti6Al4V titanium alloys for aerospace, food machinery, and industrial equipment customers. CTO Jaap Bulsink reported that the fully automated MetalFab equipment has achieved 95% utilization rates over the past several years.

K3D’s trajectory from a single MetalFab system in 2016 to a six-machine fleet producing one million parts illustrates a pattern that remains rare in metal AM: a service bureau moving from technology validation to profitable, repeatable production. The company’s origin as an internal manufacturing unit for Royal Kaak’s dough-cutting knives — a topology-optimized end-use part that won a TCT Industrial Application Award in 2019 — grounds its growth in real production economics rather than speculative capacity. The 95% utilization figure is notable because it signals that K3D has solved the workflow and order-loading challenges that keep many metal AM service bureaus operating well below capacity. Additive Industries CEO Rik Bakker noted that K3D’s first MetalFab system, delivered in 2016, remains in continuous production, which speaks to the durability of the hardware platform but also to K3D’s ability to maintain and operate it over a decade.

For the broader metal AM service bureau market, K3D’s numbers provide a grounded benchmark: seven years from first machine to one million parts, with fleet expansion paced by actual customer demand rather than speculative build-out. The company’s focus on food machinery and industrial equipment — sectors with less qualification overhead than aerospace or medical — allowed it to scale production without the long certification cycles that slow adoption in higher-regulation verticals. The practical takeaway for other service bureaus is that metal AM production at scale is achievable when the application mix, machine utilization, and customer pipeline are aligned from the start.
