Carpenter Technology Corp. announced the formation of its Carpenter Additive business unit. Carpenter Additive’s capabilities span the entire additive-manufacturing (AM) process, including: highly engineered, gas atomized powders; metal-powder lifecycle management solutions; finished component production capabilities; integrated AM and research-and-development facilities focused on technical solutions for customers; and industrial-scale AM and full post-processing capabilities.
Sintavia officially opened its new 55,000-square-foot advanced manufacturing facility in Hollywood, Fla. The facility houses over $25 million of advanced manufacturing equipment, including medium- and large-scale metal 3D printers, multiple furnaces, EDMs and post-processing machines. Some of the industrial engineering improvements of the building include separate manufacturing rooms segregated by alloy, a large-scale powder management system, an uninterruptable power supply, an inert-gas farm and a final production acceptance quality-control room.
GKN Powder Metallurgy opened its new North American headquarters and additive-manufacturing (AM) customer center in Auburn Hills, Mich. The 38,260-square-foot facility expands the company’s global 3D-printing network and extends its scope of in-house powder-metallurgy capabilities. Housing over 80 employees from the three GKN Powder Metallurgy businesses (Hoeganaes, GKN Sinter Metals and GKN Additive), the facility includes a 3,200-square-foot AM Customer Center equipped with two direct metal laser sinter (DMLS) printers.
The ExOne Company announced a collaboration with Oak Ridge National Laboratory (ORNL), the largest U.S. Department of Energy (DOE) open science laboratory, to make further advancements in 3D binder-jetting additive manufacturing. The project is initially targeted on the development of technology for new binder systems, focusing on optimizing chemistry and process parameters for ExOne’s sand and metal systems. This includes leveraging ORNL’s instrumentation and advanced data-analysis methodologies.
Quintus Technologies will deliver a hot isostatic press (HIP) with uniform rapid quenching (URQ) to the FIT Additive Manufacturing Group. Coming online in September 2019 at FIT’s main facility in Lupburg, Germany, the HIP will enable the additive-manufacturing (AM) specialist to boost productivity while meeting the heightened industrial requirements for 3D-printed metal parts. Operating at a temperature of 2552°F (1400°C) and pressure of 30,000 psi (2,070 bar), the press has a capacity of 264 pounds (120 kg) per load in a work zone that measures 10.6 inches (270 mm) in diameter and 19.7 inches (500 mm) in height.
HRL Laboratories of Malibu, Calif., is commercializing its additively manufactured (3D-printed) high-strength aluminum, which has obtained the first-ever registration of an additive alloy from the Aluminum Association. HRL will be granted registration number 7A77.50 for the aluminum powder used to additively manufacture the alloy and number 7A77.60L for the printed alloy.
Aerojet Rocketdyne Holdings Inc. acquired 3D Material Technologies (3DMT) from ARC Group Worldwide Inc. 3DMT provides additive manufacturing (3D printing) services to the aerospace, defense, medical and industrial markets. The deal complements Aerojet Rocketdyne’s capabilities to develop and produce metal-alloy AM parts for aerospace propulsion and power systems. The addition of 3DMT’s capacity and expertise in metal-alloy AM will also expand Aerojet Rocketdyne’s range of products and services.
Lincoln Electric Holdings Inc. acquired Baker Industries Inc. and related assets. Detroit, Mich.-based Baker will complement Lincoln Electric’s automation portfolio and its new metal additive-manufacturing (AM) service business that will launch in mid-2019. Leveraging Lincoln Electric’s core competencies in automation, software development and metallurgy, the metal AM business will manufacture large-scale printed metal parts, prototypes and tooling for industrial and aerospace customers. The Baker operation, along with a new Cleveland-based AM development center, will provide an AM platform to help customers improve their lead times, designs and quality in their operations.
Additive manufacturing’s promise to revolutionize industry is constrained by a widespread problem: tiny gas pockets in the final product, which can lead to cracks and other failures. Research published recently in Science, led by researchers from Carnegie Mellon University and Argonne National Laboratory, identified how and when these gas pockets form, as well as a methodology to predict their formation.
