We’re beginning this weekend’s 3D Printing Information Briefs with information from Mears Machine and Exentis Group about massive orders they’ve delivered and acquired. Then, a scholar at Kennesaw State College is researching how small design selections can have an effect on the energy of 3D printed elements. Lastly, Nugae used its ultra-light, large-format 3D printing for stage surroundings. Learn on for all the small print!
Mears Machine Delivers 3D Printed Fuel Turbine {Hardware}
Indianapolis-based Mears Machine Company just lately introduced that it had efficiently delivered a whole set of fuel turbine {hardware} to a brand new aerospace buyer. With 100 staff, over 100 machining facilities, and 4 Velo3D Sapphire XC metallic LPBF 3D printing programs, Mears focuses on manufacturing parts for missile protection, rocket launches, fuel generators, orbital automobiles, and superior propulsion programs. The propulsion system {hardware} for its new buyer order contains two Haynes 282 3D printed parts, a number of precision machined parts, and a few Inconel 718 3D printed {hardware}. The 3D printed elements underwent a mixed Sizzling Isostatic Press (HIP) and warmth remedy cycle with a purpose to enhance their properties for high-speed rotating {hardware}; these elements had been additionally polished by a specialist for improved efficiency.
“Our crew is extremely pleased with this achievement. This can be a vital milestone for Mears Machine and our buyer,” stated James Lloyd, the CEO of Mears Machine Company. “The product is a unbelievable feat of engineering, which has been realized by our world-class gear and expert staff. We want our buyer success with their testing and are excited by the expansion prospects which seem to considerably exceed our present print capability. We additionally tremendously recognize the assist of Velo3D, who because the buy of our Haynes 282 machine again in April have supplied unbelievable assist for each the machine and this product.”
Exentis Will get Order for 10 Industrial AM Techniques in Asia

Round this time final yr, Swiss firm Exentis Group AG, recognized for its distinctive 3D Additive Display screen-Printing expertise, secured a significant foothold in the U.S. market, with the sale of 9 additive programs totaling about $22.4 million. Now, the corporate is taking over a unique a part of the world, with the announcement that it has acquired one other main order, this time for 10 of its large-scale industrial programs in Asia. The corporate’s additive screen-printing is a chilly course of, working at room temperature and capable of course of a spread of supplies, together with metallic and ceramic ones. Exentis says its expertise can ship floor roughness ranges of two μm, channel widths from 125 μm, and wall thicknesses from 75 μm. The printing step is adopted by a sintering stage, however doesn’t require depowdering or machining, which speeds issues up immensely. This AM technique works for functions together with ultra-fine constructions, industrial elements, new vitality, and extra. To match with the client’s enlargement of its Asian manufacturing services, these 10 printers will probably be delivered progressively, with the primary supply deliberate for Q1 of 2026.
“We’re very happy concerning the order for ten manufacturing programs from our long-standing Asian associate,” said Dr Rolf Bachmann, CEO of Exentis Group AG. “That is yet one more affirmation of the robust demand for our distinctive and revolutionary expertise platform for really industrialised additive large-scale manufacturing, and a transparent signal of the boldness worldwide prospects place in Exentis.”
Researchers Discover how Inner Buildings Affect Print Efficiency
Eric Miller and Aaron Adams
The inner construction of a 3D printed half is simply as necessary as the surface, and if it’s not robust sufficient, the half’s energy and reliability might be restricted. Eric Miller, a mechatronics engineering scholar at Kennesaw State College and member of KSU’s START Lab throughout the Southern Polytechnic School of Engineering and Engineering Expertise, is investigating how inside constructions can affect efficiency in important industries like nuclear vitality. Beneath the steering of Division of Engineering Expertise Assistant Chair Aaron Adams, Miller’s analysis is centered round bettering half efficiency by adjusting the print settings, making small design selections to make the parts a lot stronger. As a part of their analysis, he’s designing fashions, getting ready simulations, and utilizing finite factor evaluation (FEA) to check totally different combos of lattice densities and angles, as lattice constructions and inside channels can present materials with room to increase, which improves security and effectivity. Miller will current their findings at an upcoming American Society of Mechanical Engineers (ASME) convention, and Adams believes their work may assist remedy challenges with nuclear gas effectivity.
“Proper now, the gas is within the type of a pellet concerning the dimension of a penny, and the pellets are stacked collectively like a roll of cash,” Adams defined.
“These gas pellets are then positioned inside a gas rod. When the nuclear response begins, they warmth up, increase, and are available into contact with the rod wall. As a result of they don’t have any room to increase, they have to be eliminated earlier than the gas is totally depleted, limiting how a lot of the gas can be utilized. Finally, we hope to realize a 15 p.c improve in gas utilization utilizing advanced geometries.”
Nugae’s CoreLight3D Takes Middle Stage at Garibaldi City Orchestra
Italian agency Nugae just lately used its robotic large-format additive manufacturing (LFAM) expertise to create ultra-lightweight constructions out of recycled plastics for the Garibaldi City Orchestra in Naples, a undertaking by Pessoa Luna Park, with assist from and participation by EstraMoenia throughout the Bella Piazza Mission. Nugae’s proprietary CoreLight3D—a recycled, expanded thermoplastic core—is on the heart of the undertaking, and encompasses a patented extruder, robotic kinematics for speeds as much as 300 mm/s, and a devoted slicer to allow secure deposition and partitions that, whereas described as ultra-thin, gained’t collapse because of clever stiffening and inside lattice constructions. LFAM usually means heavy objects and thick partitions, however CoreLight3D turns the idea on its head, printing extraordinarily light-weight architectures used for an inventive, city set up. Not solely does this considerably scale back Nugae’s materials utilization, however it additionally enabled the corporate to print 8 colourful, large-scale scenic parts that solely weight 3-4 kg. Plus, as a result of the surfaces of those 3D printed sea monsters are so skinny, they vibrate and amplify sound, appearing as acoustic devices within the efficiency.
“We developed this materials, which we outline as UL-LFAM, ultra-light LFAM, to construct lighter boats, however we’ve got lengthy been dedicated to themes of city regeneration and social affect,” defined Francesco Belvisi, the founding father of Nugae. “We’ve got been collaborating with Pessoa Luna Park for a while and now, with Garibaldi City Orchestra, they’ve created the best place to kick off this new revolution, which we might don’t have any hesitation in calling ‘monstrous’, particularly when in comparison with the present state of different LFAM applied sciences.”
