We’re beginning this weekend’s 3D Printing Information Briefs with information from Mears Machine and Exentis Group about giant orders they’ve delivered and acquired. Then, a pupil at Kennesaw State College is researching how small design decisions 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 Gasoline Turbine {Hardware}
Indianapolis-based Mears Machine Company just lately introduced that it had efficiently delivered a whole set of gasoline turbine {hardware} to a brand new aerospace buyer. With 100 staff, over 100 machining facilities, and 4 Velo3D Sapphire XC steel LPBF 3D printing programs, Mears makes a speciality of manufacturing parts for missile protection, rocket launches, gasoline generators, orbital autos, and superior propulsion programs. The propulsion system {hardware} for its new buyer order consists of 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 Scorching Isostatic Press (HIP) and warmth therapy cycle so as to enhance their properties for high-speed rotating {hardware}; these elements have been additionally polished by a specialist for improved efficiency.
“Our crew is extremely happy 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 improbable feat of engineering, which has been realized by our world-class tools and expert staff. We want our buyer success with their testing and are excited by the expansion prospects which seem to considerably exceed our current print capability. We additionally tremendously recognize the help of Velo3D, who for the reason that buy of our Haynes 282 machine again in April have supplied improbable help for each the machine and this product.”
Exentis Will get Order for 10 Industrial AM Programs in Asia

Round this time final yr, Swiss firm Exentis Group AG, identified 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 distinct 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 methodology works for purposes together with ultra-fine constructions, industrial elements, new vitality, and extra. To match with the client’s enlargement of its Asian manufacturing amenities, these 10 printers will probably be delivered progressively, with the primary supply deliberate for Q1 of 2026.
“We’re more than happy concerning the order for ten manufacturing programs from our long-standing Asian accomplice,” said Dr Rolf Bachmann, CEO of Exentis Group AG. “That is one more affirmation of the sturdy demand for our distinctive and revolutionary expertise platform for actually industrialised additive large-scale manufacturing, and a transparent signal of the boldness worldwide clients place in Exentis.”
Researchers Discover how Inner Constructions Affect Print Efficiency
Eric Miller and Aaron Adams
The inner construction of a 3D printed half is simply as vital as the surface, and if it’s not sturdy sufficient, the half’s energy and reliability may be restricted. Eric Miller, a mechatronics engineering pupil at Kennesaw State College and member of KSU’s START Lab throughout the Southern Polytechnic School of Engineering and Engineering Know-how, is investigating how inner constructions can affect efficiency in vital industries like nuclear vitality. Below the steerage of Division of Engineering Know-how Assistant Chair Aaron Adams, Miller’s analysis is centered round enhancing half efficiency by adjusting the print settings, making small design decisions to make the parts a lot stronger. As a part of their analysis, he’s designing fashions, making ready simulations, and utilizing finite ingredient evaluation (FEA) to check completely different combos of lattice densities and angles, as lattice constructions and inner channels can present materials with room to develop, 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, develop, and are available into contact with the rod wall. As a result of they don’t have any room to develop, they should be eliminated earlier than the gas is totally depleted, limiting how a lot of the gas can be utilized. In the end, we hope to attain a 15 p.c enhance in gas utilization utilizing advanced geometries.”
Nugae’s CoreLight3D Takes Heart 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 mission by Pessoa Luna Park, with help from and participation by EstraMoenia throughout the Bella Piazza Mission. Nugae’s proprietary CoreLight3D—a recycled, expanded thermoplastic core—is on the middle of the mission, and encompasses a patented extruder, robotic kinematics for speeds as much as 300 mm/s, and a devoted slicer to allow steady deposition and partitions that, whereas described as ultra-thin, received’t collapse due to clever stiffening and inner 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, performing as acoustic devices within the efficiency.
“We developed this materials, which we outline as UL-LFAM, ultra-light LFAM, to construct lighter boats, however now we have lengthy been dedicated to themes of city regeneration and social affect,” defined Francesco Belvisi, the founding father of Nugae. “We’ve been collaborating with Pessoa Luna Park for a while and now, with Garibaldi City Orchestra, they’ve created the perfect 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.”
