Who Is Behind GBI Group?
Neil Glazebrook – From Machining Floor to AM Visionary
Neil Glazebrook began his career in traditional machining, later transitioning to CAD/CAM sales and product management at Cimquest. He then launched AB Corp’s 60 000 sq ft 3‑D‑printing facility in Tennessee. Drawing on more than two decades of manufacturing experience, Neil founded GBI Group in Massachusetts to act as a true manufacturing partner rather than a mere machine‑time broker.
“Customers don’t need another company selling machine time. They need a partner who knows when and how to use the technology to create value.” – Neil Glazebrook
Service Philosophy: Application‑First, Process‑Second
GBI’s workflow starts with a Design‑for‑Additive‑Manufacturing (DfAM) audit. Engineers assess part geometry, tolerances, material requirements, and production volume before recommending CNC, metal powder‑bed fusion (LPBF), or polymer extrusion. This reduces the risk of costly redesigns and shortens time‑to‑market.
Benefits of the Application‑First Model
| Metric | Traditional “Machine‑Time” Model | GBI’s Application‑First Model |
|---|---|---|
| Lead time (prototype) | 4–6 weeks | 1–3 weeks |
| Design iterations | 1–2 cycles | 3–5 cycles (guided) |
| Cost per part (low volume) | $250–$400 | $150–$250 |
| Risk of non‑functional part | 30 % | <10 % |

Strategic Focus Areas
| Focus | GBI Initiative | Expected Impact |
|---|---|---|
| DfAM Integration | Early‑stage geometry analysis, topology optimization | 15 % reduction in material usage |
| Mass & Cost Reduction | Hybrid builds (CNC‑+‑LPBF) | Up to 30 % lower part weight |
| Scalability | Process standardization, repeatable build parameters | 2× faster transition to production runs |
| Supply‑Chain Resilience | Domestic sourcing, ITAR compliance | Mitigates import‑delay risk for defense contracts |
Market Outlook & Compliance
- Supply‑chain volatility is prompting U.S. manufacturers to shift 20‑30 % of critical component production in‑house.
- GBI’s ITAR registration positions it for classified defense projects, while the pursuit of AS9100 (aerospace) and ISO 9001 (general quality) certifications ensures cross‑industry credibility.
Bottom Line
GBI Group, led by seasoned AM veteran Neil Glazebrook, is redefining the role of a 3‑D‑printing service provider. By placing the application analysis ahead of the technology choice, the firm delivers faster, cheaper, and more reliable parts across CNC, metal LPBF, and polymer extrusion. Its expansive material catalog, hybrid‑process capability, and rigorous quality framework make it a compelling partner for defense, aerospace, medical, and industrial customers seeking a secure, value‑driven path from concept to production.
