“At Mayo Clinic, 3D printing isn’t a aspect mission, it’s a patient-specific service that runs on hospital time, serving to surgeons plan and act with confidence,” says Dr. Jonathan Morris, a neuroradiologist and Medical Director and Co-founder of Anatomic Modeling Unit (AMU) within the Division of Radiology at Mayo Clinic in Minnesota.
The 161-year-old establishment has constructed a 24/7 manufacturing service contained in the hospital, and it succeeds the place business gained’t. The purpose-of-care system takes surgeon orders straight from the Digital Medical File (EMR) and turns them into patient-specific instruments, fashions, and sterilizable units for the working room (OR).
“It’s a producing system that serves a hospital. It’s a service embedded within the EMR-to-OR workflow, supporting surgeons throughout subspecialties. The truth is, our return on funding is the very best consequence for a affected person who involves Mayo Clinic.”
In a current 3DPOD episode, Morris mentioned the worth of fashions and the realities of scientific adoption. In our follow-up dialog, he went additional, into the units, workflows, and high quality programs that make a hospital-based manufacturing unit work, and the sorts of bespoke affected person wants that business usually can’t or gained’t serve.
From “Cool Mannequin” to Customary Device
Mayo’s lab helps each surgical subspecialty, from craniomaxillofacial and orthopedics to skull-base neurosurgery, urology, and sophisticated oncology. Some companies are actually routine, like life-size fashions for intricate planning and sterilizable chopping guides for jaw reconstruction, together with fibula-to-jaw transfers.
The core concept is to make use of 3D printing when the case requires it. Not each affected person will get a mannequin, as a result of not each case wants one, explains Morris.
“We do it when it’s clinically acceptable, when the surgeon has a necessity. If individuals begin calling to say, ‘I want each CT scan of an enormous toe 3D printed,’ then the reply is not any. Similar to it’s not clinically acceptable to get an MRI scan for everyone who has a headache, or it’s not clinically acceptable to function on each again. It’s a medical instrument that’s run by physicians at Mayo Clinic on the level of care, constructed into the complete cloth of the establishment,” explains Morris. “Meaning any surgeon can press an order within the digital medical file system, and we then put it by means of a producing pipeline, which begins with radiology imaging. It’s not analysis funded, it’s not grant funded. It’s a scientific operation that serves the wants of Mayo Clinic.”
Morris frames fashions as learning-curve compressors. As a substitute of piecing collectively 1000’s of CT/MRI slices of their heads, newer surgeons can maintain the anatomy of their fingers and see precisely what’s the place — vessels, nerves, the tumor — so the plan clicks. Skilled surgeons don’t want a mannequin for routine instances, however they attain for one when the anatomy is uncommon or the surgical procedure is high-stakes, corresponding to a kidney tumor wrapped round vessels or a posh jaw rebuild, as a result of it lets them rehearse the method and keep away from surprises.

The place this story actually breaks new floor is in hospital-made units, options too area of interest for a conventional medtech enterprise case. Exterior breast prostheses are an excellent instance. A easy request from Mayo’s breast staff asking, “May we make these lighter and actually patient-specific?” become a full program.
“We weren’t making exterior breast prostheses. Now we’re making like 110 of them, light-weight, 3D printed, lattice construction, and matched to the opposite aspect. That now serves girls after mastectomy and congenital instances like Poland syndrome — helpful, humane, and unlikely to scale by means of business for such a small inhabitants.”
And in radiation oncology, the lab prints customized boluses and mini-beam collimator adapters for exophytic tumors and ocular instances, components that conform to anatomy and {hardware} to purpose the dose extra exactly and assist scale back pores and skin burns. None of this makes apparent business sense, but it surely makes scientific sense, explains Morris. That’s the hospital manufacturing unit’s edge: patient-first return on funding (ROI).
“Our return on funding is the very best consequence for a affected person who involves Mayo Clinic.”
Constructed Like a Actual Manufacturing unit (with Hospital Guidelines)
Morris’s staff runs 24/7, with a fleet that spans prosumer SLA as much as million-dollar industrial programs, like PolyJet, MJF, FDM, and micro-printers, supported by an 18-person cross-disciplinary employees. It’s not a “maker area.” It’s a regulated, quality-managed pipeline.
Surgeons place their requests within the EMR, and radiology runs particular scan protocols to seize manufacturing-grade information. For instance, a renal case may use a 0.6-millimeter, multi-phase CT somewhat than an ordinary research. From there, the file strikes by means of a decent high quality chain that features information checks on arrival, cautious segmentation, engineering for printability, managed printing and post-processing, and last metrology earlier than something reaches the OR.

“We’ve obtained a reasonably sturdy high quality management system, a few 0.8 mm variance on our guides. Each case goes by means of high quality management from the order to the radiology protocols. Now we have radiologic protocols particular to 3D printing, for instance, a kidney mannequin is perhaps 0.6 millimeters, with 5 phases on a particular scanner. So it’s a special order.”
They’re very correct. The 0.8 mm variance means the completed, sterilizable surgical guides differ from the supposed dimensions by lower than one millimeter on common. In apply, the holes, edges, and angles line up inside that tiny margin so the information suits the bone the way in which the plan says it ought to.
And whereas Mayo companions with corporations for what they do finest (like titanium plates from Stryker or KLS Martin), a lot of the planning, guides, and patient-specific tooling is now carried out in-house, at scientific pace.
Drugs First, Not Merchandise
On regulation and reimbursement, Morris famous that the lab operates below the apply of drugs, which suggests it serves Mayo sufferers solely and doesn’t promote units commercially.
“We’re not a medical gadget firm. We’re the Mayo Clinic hospital system that has a point-of-care manufacturing facility. However the FDA has been an incredible companion.”
Over the previous decade, that has meant steering paperwork, convention conversations, and exploratory classes at Mayo to outline what hospitals can safely do on the level of care. For now, the staff produces class II sterilizable units below tight inner controls, whereas implants (like titanium plates) proceed to come back by means of the business as Mayo works with regulators on what’s subsequent.
On billing, Mayo helped create Class III CPT codes for 3D printing—these are non permanent “monitoring” codes for brand new procedures. They let hospitals invoice and accumulate information, however insurers don’t need to pay, and once they do, the funds are sometimes restricted. The purpose is to construct sufficient proof — by means of registries (real-world case information) and scientific appropriateness standards (when it ought to be used) — to maneuver 3D printing to Class I. Class I codes are established, totally acknowledged, and way more prone to be reimbursed.
“Mainly, they show worth first, then formalize cost. The precept stays the identical: do what’s proper clinically, then align the paperwork to that actuality, not the opposite method round,” states Morris.
The Arduous Half No One Markets: Reliability
Working a number of 3D printers is messy. Machines differ, break, and wish babysitting, and post-processing isn’t standardized. In a hospital, the place timing and accuracy are life-critical, the stakes actually soar up.
“These printers usually are not mission-critical with six sigma ranges of reliability. You must function each like an vintage automotive, and you need to do far more than the operators ask you to do service. We’ve needed to struggle to get our personal employees skilled on the degree of a manufacturing unit particular person as an alternative of coping with a 3rd social gathering.”
Downtime, variability between supposedly similar machines, and a patchwork of post-processing instruments pressure Mayo to over-provision printers and prepare in-house factory-level technicians to maintain them alive. It’s costly. It’s irritating. But it surely’s price it—as a result of the choice is telling a surgeon (and a affected person) that the instrument gained’t be prepared.
At Mayo, it’s so way more than simply “3D printing helps surgical procedure.” It’s a special thesis; right here, hospitals can manufacture care.
“Whenever you embed printing, metrology, sterilization, and requirements within the scientific cloth, new therapies seem — those no firm can justify, however actual sufferers want. It’s not flashy. It’s not easy. It’s, nevertheless, a blueprint. Manufacturing has turn out to be a part of the very cloth of how we ship care to sufferers for advanced issues throughout each surgical subspecialty.”
For the AM crowd, the angle has shifted. This isn’t nearly taking a look at a medical mannequin anymore; it’s about working a hospital manufacturing unit. Level-of-care fills the markets nobody else can attain, together with congenital anomalies, uncommon reconstructions, and one-off radiation setups. And it’s not improvised. The “pipeline runs EMR-to-OR with ASTM-aligned high quality, documented accuracy, and actual sterilization validation,” explains Morris.
That leaves a transparent job for business: make {hardware} that’s dependable, straightforward to service, and constructed for the OR, and standardize post-processing, Morris provides. Repair these gaps, and hospitals like Mayo will transfer even quicker, particularly if that hospital owns the technique of manufacturing. Then, care adjustments, case by case, affected person by affected person.
