This study analyses the potential for large-scale production of Metal Injection Molding (MIM) F75 Co-Cr-Mo alloys using low-carbon atomised powders sintered in industrial-scale continuous furnaces under various atmospheric combinations. The goal was to achieve the required properties without the need for Hot Isostatic Pressing (HIP) or conventional heat treatments, promising MIM a competitive advantage for the high volume production of parts for consumer electronics and beyond. Hao-Ming Chen and colleagues, from Chenming Electronic Technology Corp. (UNEEC), Taiwan, present their findings.

As exploration of the potential of metal Binder Jetting (BJT) picks up pace, so does the diversity of materials processed using the technology. At the 2022 World PM Congress, organised by the European Powder Metallurgy Association (EPMA) and held in Lyon, October 9-13, a number of presentations reported on developments that looked at a range of materials with commercial potential for BJT, including aluminium alloys, nickel-free stainless steel, hardmetals (cemented carbides) and metallic glass. Dr David Whittaker reports for PIM International.

Die casting is a widely used process for the production of Metal Injection Molding-sized parts, but its application is typically for components with lower strength requirements. When the mechanical performance specifications for a die cast component increase, opportunities arise for alternative processes such as MIM to step in. In this case study, Ecrimesa’s Manuel Caballero reviews such a conversion process in which a zinc die cast hinge set is redesigned for production by Metal Injection Molding in 316L stainless steel in order to significantly improve mechanical properties.

How has the global Metal Injection Molding industry weathered the most turbulent years in recent history, and what has the impact been on MIM’s key markets worldwide? In this overview, PIM International’s Nick Williams reports on market data presented at World PM2022, the first Powder Metallurgy World Congress since the COVID pandemic, held in Lyon, France from October 9-13. This is supplemented by other available data sources and insight from conversations with industry leaders at the event.

HP’s Metal Jet has undergone significant refinement in the years since it was first unveiled in 2018. Now, by incorporating nearly the whole Binder Jetting workflow in one solution, HP hopes that the Metal Jet S100 – commercially launched at IMTS 2022 and showcased at Formnext 2022 – will tempt the wider manufacturing community into the world of AM. As Binder Jetting’s evolution moves from the intricacies of process optimisation to real application development and growth, Emily-Jo Hopson-VandenBos reports on a recent visit to HP’s Barcelona 3D Printing campus and the company’s progress and growing momentum since 2018.

Tritone’s MoldJet is unique as an Additive Manufacturing process – not Binder Jetting, Material Extrusion, nor Material Jetting, the MoldJet process involves a number of steps that share features with common sinter-based AM technologies, but don’t quite fall under their definitions. But this isn’t simply a novel fringe technology: Tritone’s founders have drawn on extensive experience within Israel’s 2D and 3D printing ecosystem to build a robust AM platform that is very simple, yet highly sophisticated. Joseph Kowen visited Tritone and here reports on the MoldJet process and its potential applications.

Since the very first PM Titanium conference in Brisbane, Australia, in 2011, the PMTi series has been the essential meeting point where technical and commercial advances in the powder-based production of titanium parts are discussed. Encompassing production technologies from Metal Injection Molding to Additive Manufacturing, this year’s event was no different. As Dr Thomas Ebel reports, the technologies involved have moved significantly towards production readiness, but with the ever-present playoff of non-negotiable performance goals against the drive to reduce cost.

Binder Jetting (BJT) is never far from the headlines in the worlds of Powder Metallurgy and Additive Manufacturing, but, whilst there has been a lot of emphasis on Binder Jetting’s build process, the crucial sintering stage has received less attention. Can we really go along with the assumption that it’s ‘just like sintering for Metal Injection Moulding’? Here, Markus Schneider and colleagues from GKN Sinter Metals Engineering GmbH, GKN Additive and Hoeganaes Corporation bring together their deep expertise in sintering to reveal just how differently metal BJT parts perform, and what implications there are for part design and future process optimisation.

The hardmetals industry is well used to making high-performance components from metallic powders. Today it is an industry with global sales in excess of $15 billion and applications that range from cutting tool inserts to components for oil & gas, construction and beyond. The processing of hardmetals, otherwise known as cemented carbides, by Additive Manufacturing has inevitably become an area of intense activity, building, in part, on expertise from the industry’s use of MIM to deliver greater design complexity. Bernard North reports on innovations in the sinter-based AM of hardmetals presented at this year’s Plansee Seminar.

There can be few people in Europe’s MIM industry, if not further afield, who are unaware of Prof Dr Frank Petzoldt’s contribution to the development and promotion of the technology over more than three decades. Following his recent retirement from the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM, Bremen, Germany, Dr Petzoldt spoke with Dr Georg Schlieper about the past, present and future of MIM technology and shares his insight into the industry in both Europe and worldwide.
