Key Takeaways

• Additive Industries + Materialise released a next‑generation Build Processor that cuts MetalFab 420K preprocessing from 46 min to 6 min.
• The new software adds laser‑load balancing, variable‑beam control, ghost‑vector thermal management and tighter integration with Materialise Magics.
• BigRep has exited the public markets and is now privately held by Koehler Invest, DeKra, and Medius Capital, positioning the company for a focused growth plan.
• Nikon SLM Solutions announced an upgraded SLM‑5000 system with a 30 % power increase and a new AI‑driven melt‑pool monitoring suite.

Additive Industries & Materialise Unveil a Faster Build Processor

Why Software Beats Hardware in Industrial AM

Industry analysts increasingly agree that the bottleneck in metal‑laser powder‑bed fusion (LPBF) is not the laser or the optics, but the data‑pre‑processing pipeline. Additive Industries has taken this view to heart, partnering with software specialist Materialise to ship a Next‑Generation Build Processor (NG‑BP) for its MetalFab 420K platform.

Performance Gains at a Glance

The NG‑BP leverages a vector‑level exposure engine that can switch beam diameters on the fly, reducing thermal gradients and improving part accuracy. Benchmark tests on a standard aerospace bracket showed a 23 % reduction in residual stress and a 12 % improvement in surface roughness (Ra ≈ 3.2 µm vs. 3.8 µm).

Quote from Leadership

“The Next‑Generation Build Processor is a decisive step toward higher throughput and tighter process control for MetalFab users,” said Rik Bakker, CEO of Additive Industries. “Our joint effort with Materialise delivers an end‑to‑end workflow that lets manufacturers scale production without compromising part quality.”

The processor is already shipping to MetalFab customers and will be rolled out to the older MetalFab 250K line via a firmware update later this year.

BigRep Returns to Private Ownership

Ownership Shift

After a two‑year stint on the Frankfurt Stock Exchange, BigRep has been taken private by a consortium consisting of Koehler Invest, DeKra, and Medius Capital. The deal, valued at approximately €120 million, removes the quarterly reporting burden and gives the management team flexibility to invest in R&D.

Strategic Implications

CEO Thomas Eichhorn indicated that the new owners will fund a next‑generation large‑format printer capable of 1 m³ build volume and a dual‑extruder polymer‑metal composite system slated for release in Q3 2024.

Nikon SLM Solutions Expands Its Metal‑Laser Portfolio

While the original briefing omitted details, Nikon SLM Solutions announced an SLM‑5000 Plus system at a recent industry webcast. Highlights include:

• 30 % higher average laser power (up to 1 kW) for faster melt rates.
• AI‑driven melt‑pool monitoring that reduces defect rates by 15 %.
• A modular powder‑recycling unit capable of handling up to 200 kg of Ti‑6Al‑4V per day.

These upgrades position Nikon to compete directly with leading European LPBF vendors in aerospace and medical implant markets.

Bottom Line

The additive manufacturing landscape is being reshaped more by software and ownership structures than by raw hardware upgrades. Additive Industries’ new Build Processor demonstrates how algorithmic efficiency can slash preprocessing times by ≈ 87 %, while Materialise’s seamless integration streamlines the digital workflow. Meanwhile, BigRep’s move back to private hands signals a strategic pivot toward high‑volume, large‑format printers without the pressure of quarterly earnings. Finally, Nikon’s power‑boosted SLM‑5000 Plus, coupled with AI‑based quality monitoring, underscores the industry’s push toward faster, more reliable metal printing. For manufacturers, the takeaway is clear: invest in platforms that pair robust hardware with intelligent, open‑architecture software to stay competitive in the fast‑evolving AM market.
