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.

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.

On the record.
Since 2022.
Gareth Neal has been one of the most consistently quoted voices in industrial additive manufacturing — not as a commentator, but as a practitioner with a track record of calling what happens next before it does.
Featured in 3DPrint.com, 3D Printing Industry, Develop3D, VoxelMatters, Cambridge Network, and more. Quoted alongside CEOs of 3D Systems, EOS, HP, and Stratasys in annual industry surveys. Described by 3DPrint.com as "probably the most experienced person worldwide in implementing inkjet-based 3D printing technologies."

This year will see the continuation of Additive Manufacturing's move into scale manufacturing across a variety of sectors and applications. While in many cases this change may not be obvious, as businesses protect their IP, progress will be driven on multiple fronts. From the evolution in new material properties and machine configurations, through to software developments and the definition of throughput capability by production metrics, AM and 3DP will come of age. In addition, the complexity of some projects will demand networks where companies work together to enable delivery of a complete solution. Only through collaboration and sharing knowledge across the whole supply chain will the investment, breadth of vision and capability for AM develop.
2022 saw exactly this pattern — Dyndrite, Xaar, and Meteor formalised their three-way integration partnership for binder jetting. The Xaar–Dyndrite Developer Council membership (including EOS, HP, NVIDIA, and Renishaw) was a direct embodiment of the collaborative network model Gareth described. AM adoption data confirmed quiet, IP-protected scale-up across industrial manufacturing.
The use of multi-material, multi-functional metallic, ceramic, and polymeric products that are enabled by improved inkjet printhead capability, will develop further end-use applications as design teams become more aware of how functional fluids can offer production solutions. Similarly, the adoption of inkjet as a manufacturing technology in the numerous coating applications currently conducted by analogue techniques, will deliver multiple benefits, from production efficiencies to far more sustainable production processes.
The Xaar–Quantica partnership (2023) was a direct realisation of this — extending printhead capability to 400cP for multi-material functional applications. The trajectory Gareth described is now confirmed across dental, electronics, and ceramics AM. The energy applications prediction (solid state batteries, hydrogen fuel cells) is actively emerging as a growing AM vertical through 2024–2026.
We will see the consolidation of Additive Manufacturing's move into scale manufacturing across a variety of sectors and applications. While in many cases this change may not be obvious, as businesses protect their IP, progress will be driven on multiple fronts. Be it in the evolution of new material properties and machine configurations, or software developments and the definition of throughput capability by production metrics, significant changes will be underway. Indeed, software will play an increasingly larger role as the complexities of part building becomes more widely understood. In addition, the complexity of some projects will demand networks where companies work together to enable delivery of a complete solution.
2023 was exactly the year Dyndrite delivered software-driven process control for LPBF — directly in line with Gareth's prediction that software would play an increasingly larger role. The Lincsolution MOU at Formnext 2023 — binder jetting for metal AM via a cross-company partnership — was a direct expression of the collaborative network model. On the engineering challenge: energy storage AM is accelerating through 2024–2026, exactly the trajectory Gareth identified.
2024 will see a continued focus on sustainability and efficiencies in the 3D printing industry as businesses target costly waste by leveraging technology. In binder jetting, the ability to utilise stronger binders means fewer parts will break and that larger parts can be made with increasing reliability, creating less waste and offering higher yields. Reliability and durability in inkjet printing will become the norm. On the pro side, with HP's new MJF printer and metal being released in 2023, the continuation of polyamide polymer AM will likely grow with metals being right on the tail. The adoption of AM into businesses will hopefully grow, but many are likely to make the mistake of adoption before education, leaving them with a capital expenditure without ROI.
The "adoption before education" observation proved prophetic — 2024 saw several VC-backed AM companies fail not because the technology didn't work, but because buyers hadn't been properly educated on process requirements. This was widely recognised as a structural industry problem through 2024–2025. The five-year forecast for inkjet maturing to industrial reliability is also tracking accurately.
Described in the article as "probably the most experienced person worldwide in implementing inkjet-based 3D printing technologies."
Binder jet has suffered from a fundamental misunderstanding of the technological requirements and a rush to sell from VCs. Given so many constraints, generic binder jet just doesn't have the maturity level, and we generally haven't optimised binder jet for a given market. We need to have the right binders for the right post-process and engineer the process, including software, in a much more holistic way. But binder jetting is the smallest part of that technology; it's the secondary processes that hold it back. Solve this, and then we have batch volume capacity in small, medium to high-value things with channels, rigidity, and reasonable longevity.
Desktop Metal and Velo3D — two VC-funded binder jet and AM companies — went through significant restructuring and asset sales in 2024–2025. The industry consensus aligned precisely with Gareth's assessment: the problem was never the technology, it was the business model and the failure to engineer the process holistically. Atomik AM's universal binder research addresses exactly the approach Gareth described.
Software will start to play a larger part in the overall production of metals. To be crude, rather than waving our light sabres like a broadsword, being ruthlessly dominant over all variables, rapier-like precision and control over power, shape and direction and more will be more than a possibility, a niche. It will become prevalent in those large manufacturers that have been waiting for it and are now driving it. This will drive up quality, efficiency and TCO down. Therefore, the part cost will come down, enabling more applications. That same software control will then enable newer avenues of development, such as multi-materials and material development. I have heard of as much as a 10x reduction in cost just through software.
Dyndrite's GPU-accelerated software platform is a direct embodiment of this prediction — delivering voxel-level precision control for LPBF and binder jetting. As a commercial and technical partner of Dyndrite, Gareth is actively working to realise the trajectory he described. The "light sabre" quote became one of the most shared lines from the entire annual survey.
3DPOD Episode 160 —
Inkjet AM with Gareth Neal
A full episode on the commercial and technical realities of inkjet-based additive manufacturing — covering high-viscosity applications, binder jetting, bioprinting, ceramics, electronics, and the emerging case for desktop material jetting. One of the most technically detailed podcast conversations on inkjet AM recorded to date.
In the episode, Gareth predicted that desktop material jetting using wax and printhead technology would become a commercially viable reality — at a time when the technology was considered an industrial-only capability.
Flashforge launched the WaxJet 400, WJ530, and WJ51C — described as the world's first desktop industrial wax printer. Unijet's printhead integration extended the platform further. Exactly the category Gareth described.
Gareth discussed ceramics, electronics printing, and bioprinting as applications that would open up as printhead technology advanced — arguing that most practitioners significantly underestimated inkjet's manufacturing range.
