HP's Push to Move 3D Printing Beyond Prototype Status

3D printing has been “about to go mainstream” for over a decade. HP’s industrial AM division thinks the problem is not the technology — it is the way the industry still talks about itself.

What Happened

In a piece reported by 3DPrint.com, HP’s Arvind Rangarajan argued that additive manufacturing needs to stop being positioned as experimental technology and start being evaluated as a production process competing directly with injection molding, CNC machining, and cast metal parts. His specific language: “think about additive as a manufacturing process and not as” prototyping.

The argument comes with data. HP claims it has lowered total cost of ownership for its Multi Jet Fusion systems by approximately 50% over several years through material improvements, software optimization, and workflow enhancements. The newer HP PA 11 generation 2 material produces functionally identical parts at 40% lower cost compared to standard PA 11. Strategic adjustments to part arrangement within a build — packing optimization — can reduce run costs by an additional 10%.

Rangarajan also acknowledges what has held the sector back: “overblown promises” about additive replacing conventional manufacturing wholesale. HP’s argument is not that 3D printing will replace everything — it is that for specific geometries, materials, and production contexts, it is already cost-competitive and should be selected on those merits.

Why It Matters

The proof case Rangarajan cites is orthotics and prosthetics manufacturing: HP customers now produce hundreds of thousands of customized end-use parts through distributed facilities running multiple printers continuously. This is not a prototype volume or a trade show demonstration — it is production at scale, with the economics to match.

The argument has implications beyond HP’s own product line. If the industry continues framing additive manufacturing as R&D infrastructure rather than production tooling, it limits the capital investment, process standards, and supply chain integration that would bring costs down further. The “novelty” framing is not just a messaging problem; it shapes how procurement teams, plant managers, and CFOs evaluate the technology.

HP’s cost reduction trajectory is also relevant for prosumer desktop printing. As industrial systems close the gap with conventional manufacturing economics, the manufacturing knowledge and material science developed at the high end tends to migrate downward. The cost and reliability improvements driving adoption in orthotics and automotive end-use parts are the same forces that produced the current generation of reliable desktop multi-material printers.

What This Means for Builders

For operators at any scale — from Bambu Lab desktop users to industrial FDM installations — the practical signal here is about evaluation criteria. If you are assessing whether to produce a part through additive manufacturing, the comparison should be against the full cost of the conventional alternative: tooling, lead time, inventory, and per-part cost at your expected volume. HP’s data shows that cost-per-part parity with conventional methods is achievable for the right geometry and material combination.

The three criteria Rangarajan identifies — performance, cost, and reliability — are the right framing for any additive investment decision, regardless of scale.
