Jeph Ruppert could have solely been at Fortius Metals for a few months, however he is aware of the intricacies of additive manufacturing (AM) like somebody who’s been steering the corporate for years. With a profession rooted in metallic AM, together with time at Medical Modeling and later 3D Programs after its acquisition, Ruppert has spent over a decade deep in powder-based additive. Now, he’s bringing that experience to the wire-fed world, and he sees actual potential.
“I’ve all the time been eager to know what Fortius was doing,” Ruppert tells 3DPrint.com. “It’s a small neighborhood right here on the Entrance Vary of Colorado, and I’ve been conscious of their work for years. When the chance got here as much as get entangled straight, it simply made sense.”

Fortius Metals focuses on superior alloys for Directed Power Deposition (DED), a type of wire-based AM that’s typically “overshadowed” by powder-based approaches like laser powder mattress fusion (LPBF). However that will quickly change. Ruppert is satisfied DED is prepared for progress, and he says Fortius is able to lead.
“No person welds aluminum until they need to; it’s an actual headache,” he laughs. That ache level is precisely what drew him in: “Aluminum is in all places, from plane fuselages to Tesla fenders, nevertheless it’s notoriously tough to weld. That’s why what Fortius is doing is so thrilling: we’re making historically unweldable supplies not solely weldable, however dependable for high-performance purposes in high-criticality industries.”
Supplies with Muscle
Elementum3D, Fortius’ sister firm, has developed proprietary Reactive Additive Manufacturing (RAM) expertise that’s utilized in Fortius’ RAM2 wire alloys, together with 6061RAM2 and 7075RAM2 aluminum, designed to carry out in purposes the place standard aluminum wires fall brief. These aren’t simply off-the-shelf spools. In actual fact, Ruppert describes a vertically built-in manufacturing course of that begins with large-diameter wire and ends with customer-specified diameters, full with coatings and optimized welding parameters.
“7075 is the highest of the meals chain in terms of high-strength aluminum,” Ruppert notes. “It’s extremely priceless for structural elements, particularly in aerospace and protection. Nevertheless it’s notoriously powerful to weld. That’s why we’ve spent lots of time optimizing welding parameters and maturing the fabric. It’s not nearly making the wire, it’s about guaranteeing efficiency and reliability all through the construct course of.”
The corporate can also be growing a modified model of 2024 aluminum, often known as 2024 RAM2. That is an alloy historically identified for its excessive energy and fatigue resistance, particularly in aerospace. Nevertheless, customary 2024 can also be notoriously tough to weld, explains Ruppert. So, Fortius is tailoring its RAM2 variant for wire-based AM, hoping to unlock that efficiency in DED purposes the place welding high quality and consistency are vital.
Whereas nonetheless in early improvement, Ruppert sees important potential: “It’s a difficult materials, however with the appropriate course of management, we predict we will make it viable for structural use in additive.”

In the meantime, Fortius is exploring what may very well be an actual breakthrough: a low-magnesium 5000 sequence alloy designed particularly for DED that doesn’t require post-process warmth therapy. This might eradicate one of the vital time- and cost-intensive steps in manufacturing giant, thin-walled aluminum buildings.
“Should you don’t need to warmth deal with, you keep away from the distortion dangers and the logistical complications,” he explains. “That’s particularly interesting for house and protection purposes, the place thermal biking, sensitization, and half dimension typically complicate standard approaches. We’ve acquired a proposal in proper now — if it goes by means of, it may unlock new choices for each fabrication and restore.”
Extra Than Simply Wire
Fortius isn’t simply delivery supplies, it’s constructing the workflow round them. That features a software program instrument able to operating thermo-mechanical simulations to optimize each toolpaths and welding parameters, explains the chief.
“We’re not simply making a toolpath. We’re producing the very best welding parameters alongside that path. That’s distinctive. It’s about management, about making a extra homogenous microstructure without having a PhD to run the machine. Consider it as DED meets automation. The long-term imaginative and prescient is a wire-based system as straightforward to run as a desktop FDM printer. If we will make it so simple as operating a Fortus 450, that may be nice. If we will make it so simple as a Bamboo Labs printer my five-year-old may use, then we’ve actually carried out one thing.”
Purposes That Matter
However not each market is the appropriate match, the CEO informed us. Proper now, the corporate is specializing in the aerospace, protection, and power industries the place reliability, energy, and efficiency matter most, and the place the corporate’s supplies and processes can actually stand out.
House purposes are a pure match: “Aluminum is nice for house, it’s light-weight and powerful, however once more, welding it’s a nightmare. Our supplies assist with issues like propellant tanks, cryogenic vessels, and satellite tv for pc elements,” Ruppert says.
On the protection aspect, the problem is the availability chain. Ruppert explains that there’s a lot of curiosity in utilizing stronger aluminum for floor autos. However at the moment, designs are restricted by the necessity to use weldable however weaker supplies. He believes Fortius can change that.
There’s additionally rising traction in nuclear power. Fortius’s supplies provide neutron shielding and different benefits. Because the small modular reactor (SMR) market expands, Ruppert sees actual potential: “It’s early, however the performance we will convey is de facto thrilling.”
Even electrical autos (EVs) are on the radar, however cautiously. “It’s a quantity recreation with EVs. They’re tremendous cost-sensitive, so we’d possible collaborate with others to discover that.”
Collaborating, Not Competing
One of many firm’s greatest strengths is its openness to working with others. As an alternative of attempting to construct all the pieces itself, Fortius focuses on serving to different corporations succeed with its supplies and instruments.
“There’s no clear winner in DED but,” Ruppert notes. “That’s what makes it thrilling. We wish to work with everybody, together with OEMs, integrators, and even opponents. Our job is to make the fabric work.”
Their in-house robotic welding cells, as an example, aren’t there to construct elements at scale. As an alternative, they exist to assist Fortius fine-tune its parameters and make it simpler for others to undertake its supplies. That open mindset additionally extends to Fortius’s software program technique.
“We’re nonetheless defining the enterprise mannequin,” Ruppert states. “However whether or not it’s licensing or bundling, the objective is to make DED extra accessible.”

For Ruppert, the mission is obvious: to simplify AM. He makes comparisons to metallic injection molding and the early days of robotics, each of which have been tough for most individuals to know or use.
“AM shouldn’t be a black artwork,” he says. “You shouldn’t want a military of SMEs [subject matter experts] to run a machine. We wish to democratize that.”
It’s an bold objective, however Ruppert appears decided: “Now we have to be quicker than the massive guys and extra targeted than the opposite small guys. That’s how we win.”
From unique aluminum alloys to smarter DED workflows, Fortius is quietly reshaping what wire-based AM can do. And with Ruppert on the helm, it gained’t keep quiet for lengthy.
