Heat treatment and qualification testing take printed nickel-alloy valve trims into demanding sour-gas service.
Studio 3e8 says its Mesa 1 deposits metal and scaffold material from sealed powder cartridges directly into a crucible, then sinters the part inside the same machine. The company describes a process without lasers or binders and no intermediate handling step. A Kickstarter campaign opens December 1 with pricing from $3,500; independent performance and customer production results have not been established in the report.
An external review of process controls, procedures, personnel qualifications, equipment and materials traceability underpins the accreditation. GKN expects the independent assurance to support wider industrial use of its laser-wire directed-energy-deposition route. The milestone concerns the manufacturing process, not blanket certification of every component produced with it.
A preferred-partner agreement pairs HP's Metal Jet technology with Hyperion's hard-material expertise for prototyping and production services. Hyperion has installed a Metal Jet S100 at its Barcelona facility. The new deployment is intended to widen industrial access to printed tungsten-carbide components rather than introduce the material for the first time.
Retrofit3D trim-cage example, illustrating IMI’s printed valve hardware. Photo: IMI.Seven anti-surge valves fitted with IMI’s laser-printed nickel-alloy disk stacks have entered service at TotalEnergies EP Denmark. The deployment follows a qualification programme combining additive manufacturing with a proprietary heat treatment developed for sour-gas conditions. The components must operate where hydrogen sulphide partial pressures reach 3.3 kPa, making corrosion resistance and mechanical reliability central to acceptance.
The project began with valve passing in an existing anti-surge system. Printing replacement geometry was only part of the response: IMI and TotalEnergies also had to establish that the resulting material could withstand the service environment. Mechanical and corrosion testing, together with the new heat treatment, supported DNV-ST-B203 AMC Level 3 qualification. The report says the components performed comparably with conventionally manufactured nickel-alloy parts before TotalEnergies approved their installation.
The result illustrates why post-processing belongs within the manufacturing route rather than at its end as an optional refinement. Here, the heat treatment and qualification evidence are part of what makes the printed replacement usable. The demonstrated outcome is specific to the tested components, material and operating conditions; it does not confer general approval on other printed nickel alloys or disclose a universal heat-treatment recipe. For industrial users, the relevant advance is a documented route from a maintenance problem to installed hardware.
Planned facilities in Huntington Beach, California, and Shelton, Connecticut, will combine metal printing with machining and heat treatment. Additions of DMP Flex 350 Triple machines expand Precision Resource’s existing 3D Systems fleet. Both sites are expected to be operational in the first quarter of 2027, linking capacity expansion to a more integrated route from printed part to finished component.
A Wayland Calibur3 installation gives Innsbruck researchers an open platform for difficult and high-temperature alloys. Active charge neutralization reduces dependence on powder-bed pre-sintering to prevent electrostatic smoke events. The university plans to vary beam parameters, scanning and temperature management while using thermal imaging to study process-microstructure relationships.
The European Spallation Source has placed a SEK 28 million order for tungsten-based components in its target-wheel system. Freemelt will manufacture 7,000 parts over 14 months, with most deliveries scheduled for 2027. The contract concerns an industrial production commitment rather than a laboratory demonstration.
A Rolls-Royce purchase order covers a Ti-6Al-4V structural component printed at Norsk Titanium’s Technology Center in Norway and destined for machining in Germany. Norsk is approved to supply parts for Rolls-Royce development activities. The order advances exploratory engineering within the engine supply chain; the report does not announce flight-qualified serial production of this component.
A planned A$6 million share placement will fund engine-production lines, commercial metal printers and personnel as Aurora Labs expands its small-turbojet business. Settlement is split into two tranches, with the second subject to shareholder approval. The financing supports a move toward higher output rather than proving new engine performance.
Stratasys plans to unveil a polymer production system at Formnext and bring its F870 FDM platform to Europe. The preview also highlights factory applications from Toyota and General Motors. Technical details of the new system remain to be disclosed, so the announcement is a preview rather than a verified performance advance.
Advanced Manufacturing Partners has selected Austin for a flagship factory combining metal printing, machining, depowdering and measurement equipment. Its fleet includes an AMCM M 8K alongside systems from EOS, Solukon, Zeiss and machine-tool suppliers. Customer work is already underway, with a formal opening planned for early 2027; clients retain their intellectual property.
BIZU Space engineers will receive design-for-additive-manufacturing education and engineering support through EOS Additive Minds. The Brazilian startup is exploring printed combustion chambers and closed-cycle turbopump technologies. The agreement develops engineering capability rather than announcing a qualified production engine.
Manchester Metropolitan University's planned FUSE-M facility will connect digital modelling, simulation and immersive technologies with PrintCity's manufacturing expertise. The 1,600-square-metre centre is intended to help businesses validate and adopt new processes. Its five-year programme begins with design and construction before demonstrations and collaborative projects.
A US pilot announced October 28 uses iTero intraoral scans to manufacture Invisalign Sports Guard mouthguards directly, rather than forming them over printed dental models. Participating providers will offer several thickness options. A broader commercial launch date has not been announced.
A generative model produces scaffold geometries from specified structural properties in about 12 seconds, according to a PLOS One study reported this week.

Densifying binder-jetted D2 steel is not enough: the study finds that raising sintering temperature beyond the best-performing condition can reduce strength despite a small density gain. Subsequent austenitizing, cooling and tempering reduce retained austenite and lift tensile strength to about 1.3 GPa in the tested specimens. The results argue for optimizing sintering and heat treatment together, using mechanical properties as well as density.
