From technician
to strategist.
Twenty years
of doing it.
I didn't start at a desk advising on things I'd never built. I started on the bench — making, iterating, solving. Everything I know about strategy, systems, and scale came from the work itself.
Twenty years ago I was a technician, making prototypes of mobile phone cameras. Not designing them — making them. That distinction matters. It's where I learned that the gap between a good idea and something you can actually manufacture is where most projects fail.
Started hands-on — building prototypes of mobile phone camera components. Other people's designs, but I was the one making them work in reality. That's where design for manufacture became instinct, not theory.
Moved from making to advising — identifying changes to designs that made them easier to produce, easier to manufacture at scale, and more reliable in the real world. The bridge between engineering and production.
Joined a startup developing new types of industrial inkjet printheads. Designed, developed, structured, planned, iterated, ideated. Built something genuinely new from the ground up — and learned what it takes to turn a technology into a business.
From startup to publicly listed company — a different discipline entirely. Process, governance, commercial accountability, and operating at scale. The experience that turns a specialist into a strategist.

Where AM is going.
And why it matters.
The companies still selling hardware and consumables as separate revenue streams are going to find themselves outflanked by those who integrate software, hardware, materials, and knowledge into a single offering. The value isn't in the machine. It never was.
I've watched this pattern play out across startups, Ltd companies, and PLCs. The ones who understood that the intellectual property lives in the process — not the product — are the ones still standing.
AM capability is constrained by materials science, not machine capability. The next decade belongs to whoever advances the materials.
Software, hardware, materials, and knowledge have to work as one system. Siloed expertise doesn't scale.
Most prototypes fail in production for reasons that were visible at the design stage. DfM isn't optional — it's the job.
Few people understand printhead systems at depth. That's the specialism that opens doors others can't find.
Where the work
has been done.
Prototyping and AM in regulated, high-precision environments where failure is not an option. Working with global life sciences organisations including Sartorius — delivering prototypes assembled in clean environments, meeting the exacting standards of biopharmaceutical manufacturing.
From mobile phone camera components to industrial printhead systems and additive manufacturing processes — deep experience across the full spectrum of industrial manufacturing. Design, development, iteration, and scale-up across startups, Ltd companies, and PLCs.

East of England.
Working globally.
Based in the East of England — but the work has never been confined to a postcode. Global clients, international travel, and cross-border projects are a normal part of how I operate.
Whether your project is down the road or on the other side of the world, the conversation starts the same way: what are you trying to build, and what's stopping you?
Heard enough?
Let's talk about
your project.
Six disciplines.
One conversation.
Every engagement starts with a conversation about what you're trying to achieve. The right service — or combination of services — will become clear from there. No fixed packages. No unnecessary scope.
Available for contract, consultancy, advisory, and project-based engagements. Based in the East of England — working globally.
Every project is different. The conversation is always free.
Start the ConversationPrototyping
Engineering
From a brief to a functional model — with all the iteration, problem-solving, and design-for-manufacture thinking in between. This is where it started, and it remains the core of what GN3DC does.
You have a design that needs to become something real. Or a product that works on paper but keeps failing in production. Or a team that needs specialist prototyping capability without a full-time hire.
Additive
Manufacturing
Deep, practical knowledge across AM technologies, processes, and materials — from process selection through to production workflow optimisation and Design for Additive Manufacturing (DfAM).
You're evaluating AM for a new application, struggling to scale an existing AM process, or need someone who understands the technology deeply enough to challenge your current approach.
Printhead
Technology
Industrial printhead systems for manufacturing — thermal inkjet, piezoelectric, and beyond. This is a genuinely rare specialism. Very few engineers understand printhead technology at the depth required for industrial AM and functional printing applications.
You're developing a binder jetting system, integrating industrial inkjet into a manufacturing process, or have a printhead-related challenge that most consultants simply don't have the depth to address.
System
Architecture
Designing systems that scale — from mechanical and production infrastructure through to digital, operational, and organisational architecture. The discipline that connects engineering decisions to business outcomes.
You're scaling a manufacturing operation, integrating new technology into an existing system, or need someone who can see the whole picture — not just one component of it.
Business
Strategy
Strategic advisory for technology businesses navigating growth, transition, or market entry. The difference here is technical credibility — strategy grounded in a genuine understanding of the technology, not just the spreadsheet.
You're a technology business that needs strategic clarity — and you're tired of advisors who understand business but not the technology, or vice versa.
Sales & Business
Development
Commercial execution with genuine technical credibility. Opening doors, building pipelines, and closing deals in technically complex markets — where the person selling needs to understand the product as well as the engineer who built it.
You have a technically sophisticated product and need someone who can sell it without dumbing it down — or a sales team that needs technical backing to close complex deals.
From first conversation
to delivered outcome
Tell me what you're trying to achieve. No forms, no briefs, no pitch decks required. A direct conversation is always the starting point.
Once I understand the problem, I'll propose the right approach — the service, the engagement type, the timeline, and the commercial terms.
Hands-on, direct, and accountable. I do the work — I don't subcontract it. You get Gareth Neal, not a junior with my name on the email.
A functional prototype. A clearer strategy. A closed deal. A system that works. Whatever the engagement, the outcome is always concrete.
