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.
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.
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.
SSI Sintered Specialties invested in a high-temperature refractory metal-lined vacuum furnace from Elnik Systems to expand its services into powder-metallurgy processes. The furnace, which is scheduled for installation in September 2021, will join a growing fleet of new equipment at SSI’s technology center in Janesville, Wis. Along with providing customers advanced powder-metallurgy processing, this investment positions SSI to immediately target the addition of metal 3D printing to its portfolio and the expansion of its current metal injection molding (MIM) operations. The furnace will also allow SSI to develop sintering profiles for both technologies.
Materialise opened a new 3,500-square-meter Metal Competence Center for 3D printing in Bremen, Germany. The company invested approximately $9 million to construct the facility, which has the capacity for more than 30 industrial metal 3D printers and over 120 employees. Materialise previously operated two facilities focused on metal 3D printing in Bremen, including a software development and distribution center and industrial manufacturing center. The Metal Competence Center unites and expands Materialise’s metal 3D printing sites in Bremen under one roof to support integrated production and development. It will also enable increased collaboration between software development and manufacturing teams to better serve industrial customers around the world.
Wall Colmonoy has fully installed what it says is the first Desktop Metal Shop System in the United Kingdom. Using Desktop Metal’s binder-jet technology, Wall Colmonoy can now offer affordable and fast metal 3D printing of small to medium parts. The Shop System complements the offerings of Wall Colmonoy’s Precision Components business. The division, based in Wales, encompasses a 23,500-square-foot machining facility and 19,000-square-foot casting foundry. The binder-jet printer will enable Wall Colmonoy to collaborate with customers by developing additive-manufacturing prototype or parts components, moving theoretical designs into proven applications without the restrictions of conventional subtractive manufacturing techniques. Components can be developed and manufactured for fit and function trials utilizing the company’s wear- and corrosion-resistant solutions for demanding applications or simply for end use in a desired application.
Researchers at Oak Ridge National Laboratory (ORNL) demonstrated that a new class of superalloys made of cobalt and nickel remains crack-free and defect-resistant in extreme heat, making them conducive for use in metal-based 3D-printing applications. In a study, researchers processed the cobalt and nickel class of superalloys and proved that they remained crack-free in electron-beam and laser-melting 3D-printing processes. According to ORNL, the superalloys have the material properties necessary for challenging environments because they successfully withstood the heat and also retained strength when stretched.
