In the vibrant world of industrial manufacturing, the promises of 3D printing have not always lived up to expectations. Many saw it as a revolution within reach; few succeeded in reshaping production lines. Too often, the technology ran up against material constraints, precision limits, or prohibitive economic barriers. In this sometimes disillusioned context, the Israeli startup Alumentry, founded in 2018 by Haim Baranek and father-son duo Uri and Itzik Pomerantz, truly stands out. The company has taken on one of the toughest challenges: producing high-quality aluminum parts in a way that is simple, precise, fast, and affordable—with the ambition of changing the way the world manufactures aluminum.


Today, the manufacturing of aluminum parts is dominated by CNC machining. This process, developed in the latter half of the 20th century, involves carving out a desired shape from a solid block of material with extreme precision. Reliable and well-established, it is nonetheless slow, energy-intensive, and extremely costly. It also generates enormous amounts of waste: sometimes over 80% of the original material is simply discarded.

“We created Alumentry with a four-point manifesto. First, we wanted to deliver a finished, ready-to-use part directly from a digital file, fully automated. Next, the part had to be as precise as industry standards. It also had to be manufactured in the same material already used today—without forcing the market to switch to a new type of aluminum. Finally, it needed to be cheaper than conventional methods. We start with aluminum foil and, with a special combination of physics, chemistry, and lasers, we fabricate a precise aluminum part with no compromise on properties. In the end, we get a highly precise part,” explains Uri Pomerantz, one of Alumentry’s co-founders and a trained engineer who previously worked in the machine-tool industry before diving into entrepreneurship.


For over a decade, the industry has dreamed of an additive alternative: printing instead of carving. But when it comes to aluminum, 3D printing faces well-known limitations. The printed parts are rarely usable as-is. Their finish is poor, their strength inferior, and above all, the alloys used are far from those actually employed by industrial manufacturers. “You can't print the strongest aluminum alloys—the ones used in aerospace, bicycles, or machine tools,” says Uri. As a result, machining remains the standard, even in the most cutting-edge sectors.

A Family Passion


To understand the origins of Alumentry, we have to go back to the 1980s. At the time, Uri’s father, Itzik, was running one of Israel’s pioneering 3D printing companies. In a corner of the factory, six-year-old Uri watched in fascination as early 3D printers transformed digital models into tangible objects. “My father believed you should be able to make parts directly from a digital file, without machines or manual labor. He had this very clear vision,” Uri recalls. The company eventually shut down, brought down by a technology still too immature and a market not yet ready. But the vision endured.

That childhood memory became the seed of a new ambition. In 2017, now an adult, Uri gathered two other experts—one in materials chemistry, the other in industrial production—to develop a radically new technology. The goal was not to improve an existing method but to create, from scratch, a fabrication process specifically designed for aluminum alloys.


“We wanted to start from zero. To create a technology that could produce ready-to-use final parts, with CNC-level precision, but the flexibility of 3D printing. And most importantly, using real industrial alloys—not exotic or experimental metals,” explains Haim.

A Unique Technique


At the heart of this technology lies an unexpected choice: aluminum foil. The same kind we use in kitchens—chemically reimagined. Alumentry developed a patented process that transforms this ordinary material into an extremely precise building block. Through a series of complex chemical treatments, the foil is altered so that its components separate into successive layers. This enables aluminum to be deposited layer by layer, with such fine control that even the micro-details of a part—such as threads or bores—can be directly incorporated. The results are striking.


“This gives us exceptional precision, down to just a few microns. And all of it at a cost up to 90% lower than traditional machining. We save not only material, but also time, energy, and labor. This market has a potential of $150 billion - and our technology can reduce production costs by 90%,” says Uri.


Unlike traditional metal 3D printing, which produces rough objects that must then be refined, polished, and reinforced, parts created with Alumentry’s process come out ready for use. No heavy post-processing or manual finishing required.


“We initially thought we’d sell the technology. But manufacturers are asking for the parts themselves. They want to test, handle, and see the difference. The prototype will be running in 18 months after we will finalize this funding round. At the same time, we’re raising funds to finance the next step: developing a commercial version of the machine that can produce on a larger scale. The stakes are high, because the targeted markets—aerospace, defense, automotive, electronics, robotics, and more—all need more agile, affordable, and sustainable manufacturing solutions,” says Haim.

Yet convincing investors is no easy task. The sector has been burned by unmet promises in the 3D printing space. “The people working with the parts in factories understand right away what we’re offering. But investors often still associate 3D printing with failure. They’ve seen startups promise revolutions and deliver toys or gadgets,” Uri laments.


Alumentry is aiming for the core of industry. But to succeed, it must speak to two very different audiences: the technicians, who see the potential, and the financiers, who want proof.


In a world where industry demands performance, responsiveness, and sustainability, Alumentry’s promise almost sounds too good to be true. But it is precisely because the company is built on a patiently developed vision, technical mastery, and a deeply personal history that it may well end up transforming the way we produce the objects of tomorrow.


Alumentry does not promise a revolution visible to the naked eye. It offers a decisive evolution. A change in the very material from which industry is made.
