ExOne will install a metal 3D-printing system in the Schunk Sinter Metals location in Thale, Germany, to provide serial production of sintered metal parts to automotive, aerospace, medical and other customers throughout Europe – starting with 316L stainless steel and later expanding to other materials. Schunk plans to integrate ExOne’s metal binder-jetting technology into its industrial ecosystem, which already includes other methods of 3D-printing producing parts with different materials such as copper, stainless steel and low-alloyed steel.
Desktop Metal opened a new in-house manufacturing facility in Massachusetts that will more than triple the final assembly space currently dedicated to the Production System metal 3D-printing platform. The facility is part of a strategic plan to accelerate the production ramp of Desktop Metal’s flagship Production System P-50 printer, for which the company is engaged in component procurement and assembly of initial builds targeted for shipment in the fourth quarter of 2021.
Optomec delivered a multi-functional metal additive-manufacturing (AM) machine to a supplier to the aviation engine maintenance, repair and overhaul (MRO) market. The machine combines two turbine repair process operations that are typically done manually, which not only reduces the cost of engine overhauls but also improves the quality and consistency of these flight-critical procedures. Optomec’s metal AM machines use a process called directed energy deposition (DED) to build 3D metal parts by depositing powdered metal into a precisely controlled pool of melted metal. Fiber-optic lasers supply the thermal power, while advanced motion-control systems produce the required geometries for the parts. This proprietary process precisely adds metal to worn engine components, restoring them to the geometric specifications set by the original manufacturers.
MELD Manufacturing Corp. of Christiansburg, Va., announced that its MELD technology has been selected for the U.S. Army’s Jointless Hull Program. It will be used on two machines, the larger being able to print components that are 20 feet x 30 feet x 12 feet in size. The printer will be installed at Rock Island Arsenal – Joint Manufacturing and Technology Center in 2022. A second machine will be delivered with a print volume of 5 feet x 4 feet x 3 feet.
SSI Sintered Specialties (SSI) and ExOne Company jointly announced that SSI purchased two metal binder-jetting systems featuring ExOne's patented triple advanced compaction technology (ACT). The metal 3D printers are scheduled for delivery in the first half of 2022 and will be located at SSI’s headquarters in Janesville, Wis. The company’s 250,000-square-foot facility also houses what it says is the world’s largest installed capacity of high-temperature sintering furnaces and post-processing technology to support volume production in metal binder jetting.
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.
Facility Includes Metallurgical Lab, Metal 3D Printers

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.
