3D AMUG and RAPID + TCT to generate an ML model of
properties of interest. The team then ran Alchemite optimization for high thermal conductivity and strength, arriving at a proposed alloy comprised of titanium with additives of 3-percent vanadium, 1.9-percent molyb- denum, 1.5-percent iron and smaller amounts of nickel (0.31 percent), palladium (0.13 percent) and ruthenium (0.14 percent). The program predicted this material to achieve the required thermal conductivity and
ultimate tensile strength.
GKN material experts reasoned that
high palladium costs could limit potential applications, so the team leveraged Alchemite’s ability to perform virtual experiments to consider whether an alloy with no palladium could still meet strength requirements with minimal sac- rifice of thermal conductivity. The results were obtained in seconds where other experiments would take a day, according to Intellegens officials. The crucial role of palladium in boosting thermal conduc- tivity was affirmed.
Alchemite reduced a typical 2-yr. mate- rial-design process to 3 mo., confirmed team leaders. This project reportedly also can be applied to consider other possible materials as heat-exchanger ingredients. And, experimental data can be added to Alchemite to continually improve the model and visualize the implications of process-parameter modifications, thanks to the engine’s ML capability, note Intel- legens officials.

Wide Material Portfolio in Showcase of AM Parts
Desktop Metal showcased a collection of more than 300 3D-printed production parts across a wide portfolio of materials, including metals, polymers, elastomers, ceramics, composites and even upcycled wood. One highlight was a hydraulic valve, binder-jet printed in steel by Desktop Metal’s Aidro brand that delivered a 60-
percent weight reduction along with improved performance.

New PostProcess Platform
Eases Automated Post-Processing and Connects to Full AM Production Process
ment and access to historical informa- tion
• Planning and scheduling features for efficient operation
• Remote monitoring for anytime-any- where visibility to system status and supervisory management and control
• Notification services over text or email • Enterprise-grade features such as role-based user adminis- tration, efficient license manage-
ment and robust security. “Connect3D sets the stage for
the industry’s next step-function advancement in AM,” says Rich Caplow, PostProcess vice president of product. “Today in AM, data are captured and connected in the design and printing phases, but the digital thread for a 3D part is cut off prior to its final finished stage. Connect3D links the finish- ing, or post-printing stage, to the part’s digital thread to unify the
complete workflow.”

New Spee3d Machine Part of EWI’s New Cold Spray Center of Excellence
EWI has established a center of excel- lence at its Buffalo, NY, facility (Buffalo Machine Works) to unlock the potential of cold spray—a solid-state, supersonic particle-deposition process—and mature it into a more reliable, repeatable and more-cost-effective capability, according to EWI officials. Recently delivered to out- fit the new center: a WarpSpee3d cold spray unit from Spee3d.
The goal of EWI’s cold spray initiative: advance the knowledge and capability within the field to facilitate and accel- erate the successful application of cold spray technology across manufacturing industries.
Cold spray represents one of the fastest metal-AM production techniques avail- able, providing a method for applying unique coatings and making repairs with similar or dissimilar metals. It eliminates heat affected zones and can be used on

PostProcess Technologies released its Connect3D AM platform, designed to more easily automate post-processing and connect to a user’s full AM production system. The platform, available as an annual subscription service, is the latest addition to the company’s full-stack solu- tion of hardware, chemistry and software, and complements PostProcess’ current AutoMat3D software application.
Connect3D addresses long-standing gaps in the post-printing market, accord- ing to company officials, and applies arti- ficial-intelligence and IoT capabilities to automatically generate optimized recipes for unique, part-specific requirements.
The platform reportedly integrates with factory automation systems to support initiatives that automate lights-out man- ufacturing for high-scale part production. Its open-architecture design includes pub- lic APIs to unify the additive digital thread and interoperate with third-party software applications across the additive workflow, such as MES solutions, print management software and CAD applications.
Connect3D features include:
• Intuitive presentation of alerts and alarms for real-time operations manage-
