Centorr Vacuum Industries, to satisfy multiple orders, is currently building two furnaces designed for the metal 3D-printing and metal injection molding (MIM) industries. Sintervac AM is designed for debinding and sintering. It is outfitted with a graphite hot zone and operates in vacuum, partial pressure or positive pressure of forming gas. It also has a dual trapping system to handle the process off-gassing from binder-jet 3D-manufactured parts. MIM-Vac, which has multi-zone temperature control for improved processing uniformity, has the ability to handle virtually any metal feedstock.
Desktop Metal Inc. and ExOne Company entered into a definitive agreement pursuant to which Desktop Metal will acquire all of the issued and outstanding shares of ExOne common stock. The transaction is valued at approximately $575 million. A pioneer in binder-jet 3D-printing technology, ExOne manufactures metal 3D-printing systems. The North Huntingdon, Pa.-based company also provides specialized 3D-printing services, including on-demand production of mission-critical parts, engineering and design consulting. Based in Burlington, Mass., Desktop Metal designs and manufactures a range of metal 3D-printing systems. The company offers an expansive portfolio of 3D-printing solutions, from rapid prototyping to mass production.
Many components and assemblies have internal features that are difficult to inspect, none more so than additively manufactured (AM) parts. Conventional quality control requires samples to be sectioned and subsequently scrapped. However, the advent in the 1980s of X-ray computed tomography (CT) for industrial material analysis and nondestructive testing heralded a new era for inspection of such parts, both internally and externally.
Burloak Technologies Inc., a division of Samuel, Son & Co. Ltd., established an additive-manufacturing center in Camarillo, Calif. With the addition of this facility, the company becomes North America’s first multi-site AM services provider. The new 25,000-square-foot facility bolsters the manufacturing capacity available at Burloak’s 65,000-square-foot Additive Manufacturing Center of Excellence in Oakville, Ontario. Between the two facilities, the company offers laser powder-bed fusion, electron-beam powder bed, metal binder jet, and powder and wire DED technologies. In addition, Burloak offers post-production services including design, engineering, CNC machining, heat treatment and finishing.
Desktop Metal acquired Aerosint, a provider of multi-material deposition systems for powder-based additive manufacturing (AM). Based in Belgium, Aerosint offers a powder deposition system based on a proprietary digital process that selectively deposits two or more powders to form a single, thin powder layer containing multiple materials. The company’s patented selective powder deposition technology enables full three-dimensional control of material placement during printing. It can be integrated into any powder-bed AM process, such as laser powder-bed fusion, binder jetting, high-speed sintering or selective laser sintering. This multi-material approach to powder deposition is designed to support high-speed printing of a broad range of metals, polymers and ceramics.

Relativity Space, the first company to 3D print an entire rocket, announced a major expansion of its operations in Long Beach, Calif., with a new, 1,000,000-square-foot headquarters factory at Goodman Commerce Center. Relativity Headquarters will have capacity for over 2,000 employees, a metallurgical laboratory, DMLS printers and a mission control center. It will also have dozens of the company’s proprietary Stargate 3D printers, which it says are the largest metal 3D printers in the world. With software changes, Relativity’s Stargate printers are capable of printing both Terran 1, the world’s first entirely 3D-printed launch vehicle, and its fully reusable, entirely 3D-printed rocket, Terran R. Move-in is scheduled for January 2022.
Penn State University purchased a high-speed metal 3D printer from Australia’s SPEE3D. The investment into a LightSPEE3D cold-spray metal 3D printer will allow the institution to advance its additive-manufacturing (AM) capability. The university’s Applied Research Laboratory will adopt SPEE3D’s high-speed metal 3D-printing technology to meet the materials and manufacturing challenges of the U.S. Navy, Department of Defense and the industrial base. According to SPEE3D, its metal 3D printers run at a speed 100 to 1,000 times faster than traditional metal 3D-printing methods. They leverage cold-spray technology, which can produce industrial-quality metal parts in just minutes.
Abbott Furnace and ExOne, a provider of 3D-printing systems, are collaborating on the use of continuous furnaces for sintering of aluminum and high-volume binder-jet applications. ExOne announced in March that it had begun successfully binder-jet printing and sintering 6061 aluminum. While most binder-jet 3D printers sold today are paired with a batch sintering furnace, ExOne found – with Abbott’s assistance – that Al 6061 preferred a continuous furnace that would be advantageous in high-volume production.
Sciaky Inc., a subsidiary of Phillips Service Industries (PSI) and a supplier of industrial metal 3D-printing solutions, received a Small Business Innovation Research (SBIR) award from NASA. The objective of the SBIR is to enhance Sciaky’s electron-beam additive-manufacturing (EBAM) process with new machine-learning algorithms that automatically identify and eliminate defects with titanium (Ti-6Al-4V) 3D-printed parts and structures. The machine-learning algorithms will utilize Sciaky’s patented interlayer real-time imaging and sensing system (IRISS) to monitor titanium deposition, identify anomalies and fix them. These intuitive adaptive control features will help manufacturers deliver consistent results.
Thermal-processing companies around the world are feeling pressure to lower the environmental impact of their operations and make them more sustainable. These pressures are coming from both governmental regulations and societal expectations, resulting in increasingly stringent requirements that are expanding globally. Many companies are accelerating their own “green” initiatives and programs to leap ahead of these regulations and lead this transformation for their industry. Join this free webinar, sponsored by Honeywell, on June 3 at 11:00 a.m. (EDT) to learn more about the solutions that are available today to help achieve your sustainability goals.
