Additive manufacturing has produced a decade of impressive medical demos that never left the trade-show booth, and the reason is almost never the geometry. It is the billing. So the most interesting line in Kalogon's 20 July announcement of Verro, a new custom wheelchair cushion line, is not the lattice — it is five characters: E2609. That is the Medicare code Verro carries, and it is the difference between a clever printed part and a clinical product a seating therapist can actually prescribe.
Two cushions, one of them printed
Verro launches in two models. Verro Lattice is the headline: a 3D printed elastomer built with what Kalogon calls patent-pending variable-density lattice technology. Firmness varies across the cushion surface — firmer where the body needs to be held in position, softer where pressure needs to be diffused. Verro Foam is the conventional sibling, a dual-density build pairing a custom-cut dense foam base with a soft foam topper.
Both are custom-built per user, and both are ordered through Launch Pad, Kalogon's configurator. A clinician either supplies a 3D scan of a physical mold taken with the user in the desired seated position, or enters detailed measurements. From there the job goes to Kalogon's own facility in Melbourne, Florida, with cushions shipping within 14 days of order receipt. That arrangement will look familiar to anyone who has run a print farm: no inventory, no SKU matrix, just a queue of one-off geometries derived from customer data.
The target population is specific: wheelchair users with windswept posture, pelvic obliquity, and asymmetry — the seating cases where a symmetric off-the-shelf cushion is not merely suboptimal but actively wrong. CEO and founder Tim Balz frames the origin bluntly: "We kept hearing from clinicians that their most complex patients were falling through the cracks, so we developed a technology that lets us 3D print the cushion with precise, localized control over where the body gets support and where it gets relief." On what the process buys, he is more specific: "With our variable-density lattice, we can create subtle variations across the surface and sides of the cushion that simply aren't possible with traditional materials."
That claim is narrower and more defensible than the usual lattice marketing. Carved foam can be shaped, but it cannot easily change stiffness continuously through a volume without seams, glue lines, or density blocks that telegraph their edges into the skin. A printed lattice varies its effective modulus through strut thickness, cell size, and topology — a stiffness field rather than stiffness zones. For a body asymmetric along multiple axes, that continuity is the engineering argument.
The unglamorous specs are the interesting ones
Strip away the lattice novelty and the spec sheet reads like a list of long-term cushion users' complaints, answered one at a time. The open lattice lets air move freely through the cushion, which Kalogon pitches as temperature and moisture management at the seating interface — a clinical concern, not a comfort nicety. The material is hydrophobic, so liquid passes through rather than soaking in, and the cushion is dishwasher safe on the top rack. Verro Lattice ships with a vapor-permeable outer cover and an optional incontinence liner; on Verro Foam, the liner is included. And the lattice weighs up to two pounds less than a standard cushion, which for a manual wheelchair user propelling their own chair all day is not a rounding error.
Every one of those properties falls out of the geometry for free: an open lattice is breathable and light because it is mostly air, and washable because there is no closed-cell foam to hold water and no laminated assembly to delaminate. That is what a well-chosen additive application looks like — not a subtractive job done more expensively, but a part whose secondary properties are inseparable from the printed structure.
Why the Foam model matters more than it looks
Shipping Verro Foam alongside the printed model is a deliberate hedge, and a revealing one. Its selling point is that the dense foam base can be carved and adjusted after delivery, giving seating specialists flexibility if a user's needs change over time — material comes out in the clinic when a user's posture shifts, or when the initial capture missed something.
You cannot do that to a lattice. A printed cushion's tuning is locked the moment the file is sent, so the accuracy of the scan or the configurator entry has to carry the clinical outcome. Kalogon advisor Kelly Waugh, MA, PT, ATP, puts the split in matching terms: "Every client is different, and seating specialists need options that reflect that. Verro gives us more ways to match the right solution to each unique person based on their postural support needs, personal preferences and desire for in-field modification." Read that last clause as an admission that printed is not universally better. It wins when the capture is good, the geometry is complicated enough to defeat foam, and the user's posture is stable enough that a fixed part stays correct. Otherwise, modifiability wins.
What It Means for Makers
The lesson here is not "print a lattice." Any maker with a parametric toolchain and soft TPU can make something that looks the part. The lesson is that Kalogon spent its effort on the two things hobbyist and startup projects almost always skip: a repeatable body-capture pipeline that yields a manufacturable file without an engineer in the loop, and a reimbursement pathway.
The capture side is the quiet achievement. A clinician who is not a CAD user has to generate a valid custom part, from a scan of a seated mold or from typed measurements. That is a production problem disguised as a UX problem — the bottleneck on every made-to-order printed-goods business that has ever stalled.
The code is the harder one. Carrying E2609 puts Verro inside the reimbursement system rather than outside it, where a clinician can prescribe it like any other custom seating component. Without a code, a printed custom cushion is a cash-pay item aimed at a population that frequently cannot absorb the cost. With one, it competes with carved foam on clinical merit. If you are building anything additive that touches healthcare, mobility, or assistive tech, the billing code is not paperwork you get to after the prototype works. It is the product requirement that determines whether the prototype ever matters.
Kalogon, founded in 2019, spent its first years on smart pressure-relief cushions built around sensors and adaptive surfaces before expanding into custom 3D printed seating with Verro. Verro is the quieter of the two products, and probably the more consequential — because it ships with a way to get paid for.
