The Lattice Brief, November 8, 2026. This week in healthcare 3D printing: a printed socket can cost under $10 in material, yet only 1 in 10 people who need assistive devices get one. The constraint is clinicians, reimbursement and evidence, not the printer. Also: restor3d takes its printed hip cup to full release, Kallisio’s printed oral stents ship in 72 hours, a study finds 1 in 5 printed temporary dentures fractured, and a French team prints a lung phantom for comparing scans.

The big thing

Printed prosthetics: the printer is the easy part

In 1990, Northwestern University and Baxter Healthcare printed a prosthetic socket with stereolithography. Thirty-six years later, HP and DyeMansion are running a webinar on printing them by the hundreds. Nobody asks whether a printer can make a socket anymore. The question is whether anyone can deliver one per patient, get paid for it and keep it on the limb.

Material is no longer the cost. A printed socket can cost under $10 in material. Yet the WHO estimates only 1 in 10 people who need assistive products, prostheses and orthoses included, get them: about 3% in poorer countries, 90% in wealthy ones. Printing lowers the cost of a socket. It does not create prosthetists, payers or follow-up visits. India has roughly one prosthetist-orthotist per million people. The WHO recommends five to ten.

The evidence is promising but thin. A 2025 review of 62 studies found printed orthoses improved gait, comfort and fit. Every study in an updated review of printed ankle-foot orthoses had fewer than 12 participants. Most socket studies track durability for only 2 to 6 weeks. Payers notice.

So value goes to whoever owns the clinical workflow and the reimbursement code. Open Bionics opened its own clinics and won NHS coverage. In the US, many advanced hands still bill under a miscellaneous code. This week, Western Cape public hospitals in South Africa began delivering printed spinal braces in 48 hours instead of two weeks. A health system set that pace, not a printer.

My view: the printer is a feature. The business is the clinic, the reimbursement code and the follow-up visit. Our new 3DHEALS guide to 3D printed orthotics and prosthetics maps the history, companies, market and access gap in-depth.

Join us Thursday, November 12, for Next-Gen 3D Printed Orthotics and Prosthetics with Jade Ward (AMPrint Center, Rochester Institute of Technology), Tergel Bayarsaikhan (Rightfit), Kaiyan Qiu (Washington State University), Louis-Philippe Broze (Spentys) and Schendy Kernizan (Rapid Liquid Print). Tell us what is holding back printed O&P in your clinic.

• Guide: 3D Printed Orthotics and Prosthetics: The 3DHEALS Guide. Our long-form guide to printed O&P: the history from e-NABLE to neural interfaces, the companies, market estimates that disagree by a factor of six, regional economics and why only 1 in 10 people get the device they need.
• Podcast: Bonus episode: Why 3D printed prosthetics still don’t reach most people. A two-and-a-half-minute companion to the guide on the access gap.
• Event, Thu Nov 12: Next-Gen 3D Printed Orthotics and Prosthetics. Jade Ward (AMPrint Center, RIT), Tergel Bayarsaikhan (Rightfit), Kaiyan Qiu (Washington State University), Louis-Philippe Broze (Spentys) and Schendy Kernizan (Rapid Liquid Print) on what it takes to make printed O&P routine.

Regulatory watch

No new FDA 510(k) clearances for additively manufactured devices turned up this week. The regulated-device news was about commercial rollout of devices already cleared.

• restor3d moves its Velora hip cup to full commercial release (3D Printing Industry, Nov 6). The 3D-printed porous titanium cup (FDA 510(k) K252067, cleared December 2025) leaves limited release this month. The first Identity Kinematic Alignment knee cases are done, and the printed Identity 3DP Porous knee targets full release in 2027.
• Kallisio streamlines production of personalized oral stents for cancer patients (VoxelMatters, Nov 5). Stentra holds the tongue and jaw still during head and neck radiation. It is FDA-cleared and CE-marked, printed in nylon by Myrava from an intraoral scan, ships within 72 hours, and bills under CPT 77334. Note the last part. That is the reimbursement code our big thing is about.
• BioSummer Dental adds 3D Systems’ NextDent 300 to its distribution portfolio (VoxelMatters, Nov 3). The French distributor will sell the jetted-denture printer, which earned EU MDR Class IIa certification this spring, to dental labs.

Clinical & research

• Clinical performance of additively manufactured interim complete-arch dental prostheses for immediate implant loading (Journal of Dentistry, via PubMed). Across four Italian centers, 15 of 77 printed-resin temporary full-arch prostheses (19.5%) fractured, and 13 arches broke again after being reprinted from the same file. Implant survival was 99%. Why it matters: a fracture is a design problem, and pressing print again does not fix it.
• Pulmonary embolism 3D printing model for inter-modality imaging study (3D Printing in Medicine). A Brest University Hospital team printed a watertight lung with a separately fillable segment that mimics a 5% perfusion defect, so one clot can be imaged by scintigraphy, PET/CT and dual-energy CT. Readers rated the images highly realistic. Estimated cost: EUR 770 per print. Why it matters: cheap, custom phantoms make it practical to compare scanners and protocols against a known answer.
• Robotic winding of wet-spun fibers for biofabrication of aligned, perfusable, muscle-based tissue (Biofabrication, via PubMed). University of Minnesota researchers used a robot arm to wind continuous fibers of muscle and blood-vessel cells around organ scaffolds, building aligned, perfusable muscle from the inside out. Why it matters: scale-up, not cell biology, is the usual bottleneck for engineered muscle.

Also this week

• Western Cape patients get custom 3D-printed spinal braces in just 48 hours (Cape Times). A public-sector scan-and-print brace service, launched on International Prosthetics and Orthotics Day, cuts the wait from about two weeks.
• 3D printed prosthetics have come a long way: HP and DyeMansion look at what’s next (3DPrint.com). A preview of the two companies’ Nov 10 webinar on scaling printed O&P, from scanning to finishing.
• 3D printing technology set to speed up prosthetics production (CBC Barbados). Queen Elizabeth Hospital in Barbados is raising funds to add 3D printing to its prosthetics department.
• 3D Systems reports third quarter 2026 results (GlobeNewswire). Healthcare revenue rose 14% to $49.0 million, with dental materials and medical parts each up more than 20%. The net loss widened to $33.5 million.
• 3D bioprinting of vascularized cardiac constructs (Journal of Pharmacy & Pharmaceutical Sciences). Saskatchewan and Manitoba researchers found bioprinted heart patches with vessel-like networks beat in sync by day 21. Patches without them beat irregularly.
• AI helps find better recipes for 3D-printing titanium parts (TechXplore). An explainable machine-learning model, trained on 201 published experiments, suggests laser settings for Ti6Al4V, the alloy behind most printed implants.
• Fireline: the logic and strategy behind the Form Studio 1 (3DPrint.com). Formlabs’ $669 desktop resin printer, and Joris Peels’ argument that the real prize is selling trusted resin to dentists who buy cheap printers.
• Design software reimagines everyday objects as self-aware devices (MIT News). MIT’s X-Hinges prints touch and motion sensing into hinged objects, including a glove that teaches a robot hand to grasp.
