Key Takeaways
- MTC has added Caracol’s Vipra XP AM robotic DED‑Arc system to its NCAM portfolio.
- The platform offers a 6‑axis robotic arm, up to 1.2 m × 0.6 m × 0.5 m build envelope and 20 kW arc power.
- Supports a broad alloy suite (Ti‑6Al‑4V, Inconel 718, 316L, Al‑7075, etc.) with real‑time sensor feedback via Caracol’s Eidos Manufacturing software.
- Expands MTC’s ability to qualify large‑format metal AM for aerospace, defence, automotive, rail and energy sectors where part size and material performance are critical.
MTC Boosts National Additive Manufacturing Capacity
The Manufacturing Technology Centre (MTC)—a flagship of the UK’s High Value Manufacturing Catapult and partner of Innovate UK—has selected Caracol’s Vipra XP AM as the newest addition to the National Centre for Additive Manufacturing (NCAM).
MTC’s role is to translate cutting‑edge research into production‑ready solutions for a client base that ranges from global OEMs to specialist SMEs. By integrating the Vipra XP AM system, the centre can now address large‑format metal additive manufacturing challenges that demand:
- Part dimensions beyond 1 m in length,
- High‑performance alloys with strict mechanical tolerances, and
- Flexible production pathways for low‑volume, high‑value series.
What Sets Vipra XP AM Apart?
Robotic DED‑Arc Architecture
- 6‑axis KUKA robot provides 5 µm positioning repeatability.
- Arc power: 20 kW (max) enables deposition rates up to 12 kg h⁻¹ for Inconel 718.
- Build volume: 1.2 m (L) × 0.6 m (W) × 0.5 m (H).
Material Flexibility
| Alloy | Typical Yield Strength* | Recommended Deposition Rate |
|---|---|---|
| Ti‑6Al‑4V | 880 MPa | 4–6 kg h⁻¹ |
| Inconel 718 | 1 080 MPa | 8–12 kg h⁻¹ |
| 316L SS | 290 MPa | 10–14 kg h⁻¹ |
| Al‑7075 | 570 MPa | 3–5 kg h⁻¹ |
*Yield strength measured after standard heat‑treatment.
Integrated Process Control
Caracol’s proprietary Eidos Manufacturing suite links tool‑path generation, arc parameter tuning, and a multi‑sensor package (laser profilometer, IR pyrometer, high‑speed camera). The data pipeline delivers:
- In‑process melt‑pool monitoring (±5 µm resolution).
- Real‑time defect detection (porosity > 0.5 %).
- Post‑build data visualisation for qualification reporting.
How Vipra XP AM Compares with Competing DED Technologies
| Feature | Vipra XP AM (Caracol) | EOS M 290 (Laser DED) | Traditional GTAW DED |
|---|---|---|---|
| Energy source | Arc (20 kW) | Laser (4 kW) | Arc (≤15 kW) |
| Build envelope | 1.2 × 0.6 × 0.5 m | 0.6 × 0.5 × 0.5 m | 0.8 × 0.4 × 0.3 m |
| Deposition rate (Inconel 718) | 12 kg h⁻¹ | 6 kg h⁻¹ | 4 kg h⁻¹ |
| Alloy coverage | 15+ (incl. Al, Ti, Ni, Fe) | 8+ (primarily Ni, Fe) | 5+ (mostly Fe, Ni) |
| Process monitoring | Full sensor suite, AI‑driven defect alerts | Limited pyrometer, no AI | Manual inspection only |
| Capital cost (approx.) | £1.2 M | £1.6 M | £0.9 M |

Strategic Impact for MTC and Its Industrial Partners
The addition of Vipra XP AM enables MTC to:
- Accelerate qualification cycles for large‑scale aerospace brackets and defence‑grade structural components.
- Offer low‑volume production runs for automotive power‑train housings where traditional casting is uneconomical.
- Provide a testbed for hybrid manufacturing (DED + subtractive milling) under the same robotic framework.
MTC’s multidisciplinary team—spanning materials scientists, robotics engineers, and data analysts—can now exploit end‑to‑end digital thread from design to certification, a capability that aligns with the UK’s “Made Smarter” agenda.
Bottom Line
Caracol’s Vipra XP AM robotic DED‑Arc platform dramatically expands the National Centre for Additive Manufacturing’s ability to produce and qualify large‑format metal parts across a spectrum of high‑value industries. With a generous build volume, high deposition rates, and a sophisticated sensor‑driven software ecosystem, the system positions MTC at the forefront of UK metal additive manufacturing, delivering the flexibility and performance that aerospace, defence, automotive, rail and energy sectors increasingly demand.
