From requirement to reality: How DEEP Manufacturing is scaling large-format metal AM

DEEP Manufacturing is not a conventional metal Additive Manufacturing company. Established to support the wider DEEP Group’s ambition of enabling long-duration human habitation beneath the sea, the privately backed organisation is part of a programme supported by more than $230 million in publicly reported investment across the UK and US.

Metal AM’s Martin McMahon, Emma Lawn and Nick Williams visited DEEP Manufacturing’s Avonmouth facility and spoke with COO Louise Slade about how an ambitious subsea habitat programme created one of the largest wire-arc DED operations.

From titanium scrap to AM powder: Inside 6K Additive’s UniMelt expansion

As aerospace, defence and energy manufacturers look more closely at where critical metal powders come from, recycled feedstocks are moving from sustainability story to strategic supply chain issue. 6K Additive is addressing that shift by combining recycled metal inputs with UniMelt microwave plasma technology to produce titanium-, nickel- and refractory-metal powders for Additive Manufacturing and advanced industrial applications.

Following a visit to Burgettstown, Pennsylvania, Bernard North examines the technology, qualification activity and expansion strategy behind the company’s growth.

Scaling metal AM for maritime spare parts: From legacy portfolios to on-demand supply

Metal Additive Manufacturing is increasingly capable of producing qualified end-use parts, but for maritime OEMs the greater challenge is delivering those parts consistently, securely and at scale. For operators supporting long-lived vessels and offshore assets, legacy spare parts present a persistent service and inventory challenge.

Håkon Ellekjær, CEO, and Scott Harding, VP Engineering, of Pelagus, a joint venture between Wilhelmsen and thyssenkrupp, examine how digital inventory, traceability and qualified manufacturing networks are enabling controlled, on-demand production.

Building trust in flight-critical metal AM: Inside the SAE AMS AM standards committee

Standards rarely attract the attention given to new Additive Manufacturing machines, materials or applications, but in aerospace AM they are essential to progress.

Reporting from the SAE AMS AM Metals Sub-Committee’s spring meeting at GKN Aerospace in Trollhättan, Sweden, Chair Dr Tyler LeBrun offers an inside view of the consensus work shaping flight-critical metal AM, from machine qualification and process control to in-situ monitoring, powder management, Nadcap accreditation and future inclusion in MMPDS.

Incodema3D boosts metal AM productivity with HK Technologies’ VacuSift powder handling system

As Incodema3D scaled its EOS metal AM fleet to support aerospace, defence and energy production, manual powder recovery and sieving became a constraint on machine utilisation, material yield and operator efficiency. Working with HK Technologies, the New York State manufacturer implemented the VacuSift Powder Conveying and Sifting System to automate powder recovery, screening and transfer.

In this article, HK Technologies describes how the implementation improved machine turnover, powder reclamation and workflow repeatability in high-volume metal AM production.
