A patient you may fail on.
A patient you may fail on.
In the operating room, you cannot fail.
In our laboratory, you must.
The world’s first patient-specific medical clone.
Printed at 0.02mm, in full color, in multiple materials, as a single build.
Bleeds when cut. Holds body temperature.
Co-created in Japan by MEDiDENT × MIRISE × NICHINAN.
The patient you're allowed to practice on.
練習できる患者さんを、創造する。
The one model that surgeons truly needed.
Robotic-assisted surgery, microvascular anastomosis, minimally invasive techniques — modern surgery has entered an era demanding unprecedented precision and sophistication. We are now providing, from Japan, a ‘place of learning’ that meets those demands.
In surgery, ‘firsts’ are unavoidable. No matter how many papers you read, videos you watch, or mentors you shadow, the first scalpel must eventually be placed on a living person. That is a fact surgeons have long carried, yet rarely spoken aloud.
Cadavers are scarce. Animal models have limits. Mannequins give nothing back when you touch them. So we built one.
From the patient’s own CT and MRI, we place their body here as a physical object at 0.02 mm precision. Bone hardness, mucosal softness, skin color, body temperature, vascular pathways, blood pressure, nerve positions — everything reproduced in a single build.
Before the operation, you meet that patient once in advance. You rehearse the procedure with your own hands. Young surgeons fail here as many times as needed, building technique into their bodies. So that the moment they enter the operating room, it is already their ‘second time.’
This is the design philosophy of the 3D Clone Model Platform. Not a teaching aid for education, but a second operating room before the real one — for safe surgery. What frontline surgeons truly needed, delivered here.
Diagnostic to Physical
Diagnostic to Physical
The 3D Clone Model Platform integrates patient-specific CT, MRI, and scan data to materialize it with an ultra-high precision of 0.02mm. From hard bones to soft skin and mucous membranes, multiple materials are reproduced in an integrated molding.
By providing an environment where you can actually "touch and learn" rather than just a model, it improves the accuracy of preoperative planning and strengthens the collaboration of team medicine.
In the future, through collaboration with XR (Cross Reality) and AI, we aim for further educational innovation such as reproduction of bleeding by a circulation pump, body temperature simulation, and objective evaluation of procedures by sensors.
Starting from the most difficult "Face",
to every part of the whole body
The initial prototype of this project started with the "face", which has the most complex anatomical structure in the human body. The fact that we were able to reproduce the facial area where teeth, gums, tongue, mucous membranes, bones, muscles, nerves, and blood vessels are densely packed with 0.02mm precision is proof of our technological capabilities.
Currently, this platform is evolving into a scalable foundation that can be expanded not only to the face but also to various parts of the whole body, such as tongue cancer, oral surgery areas, kidneys, brain, heart, blood vessels, and skeleton.
Four axes. One platform.
四つの軸。ひとつの基盤。
Education
Surgical training for the next generation
Young surgeons rehearse incision, suturing, and hemostasis on patient-specific clones — building muscle memory in a zero-risk environment before entering the operating room.
Surgery
Preoperative simulation & team rehearsal
The entire surgical team — surgeon, anesthesiologist, nurses — rehearses the exact procedure on the patient’s own anatomy, reducing operating time and improving outcomes.
Patient
Informed consent & shared understanding
Patients hold their own anatomy in their hands. A three-dimensional, tactile explanation replaces flat images and verbal descriptions, transforming informed consent.
Research
Evidence-based surgical science
Sensor-equipped clones log every cut, every suture. AI analyzes technique objectively — turning surgical training from apprenticeship into measurable science.
Not a "patient you can fail on",
— Daisuke Tomita, MEDiDENT CEO
but creating a safe training environment
so you don't fail in clinical practice.
Five layers. No single layer is sufficient.
五つの層。どの一層も、それだけでは足りない。
Most 3D-printing companies can produce a shape. A few can produce a multi-material shape. Almost none can produce a patient-specific, multi-material, physically accurate medical clone that a surgeon would trust enough to rehearse on.
The reason is not any single technology. It is the integration of five capabilities that have never before existed inside one organization.
Clinical interpretation of imaging data
CT/MRI data is not a blueprint. Translating Hounsfield units into clinically meaningful anatomy requires deep surgical knowledge — not just engineering.
Voxel-based volumetric rendering
Proprietary conversion logic maps HU values to physical properties — density, elasticity, color — at voxel resolution.
Multi-material monolithic fabrication
NICHINAN’s precision manufacturing integrates bone, mucosa, skin, and vasculature into a single build at 0.02mm resolution.
Triangular co-creation model
MEDiDENT (business architecture) × MIRISE (clinical validation) × NICHINAN (precision engineering) — three capabilities that do not exist inside any single company.
Validated at global scale
Stanford debut, Gold Award, MedTech World Award, FII Priority ASIA invitation, university integrations across 8+ countries. Not a prototype — a platform with traction.
Three summits, at one table.
三つの頂が、ひとつの卓に集まった。
This platform is not the product of a single company. It is the convergence of three domains — business architecture, clinical medicine, and precision engineering — each led by a principal who has spent decades at the frontier of their field.

A graduate of Showa University School of Dentistry and Tokyo Medical and Dental University Graduate School, Tomita built a 23-year clinical partnership between orthodontics and oral surgery, pioneering Surgery First and Early Surgery protocols at the intersection of both disciplines. He served as Assistant Chief of Orthodontics at Tokyo Medical and Dental University Hospital and as a full-time supervising clinician at Yokohama City University Medical Center before founding the MIRISE Well Medical Group — seven facilities spanning orthodontics, oral surgery, regenerative medicine, and a dental laboratory, all under one governance. In 2023 he completed Harvard Medical School’s Executive Education in Leading Digital Healthcare Transformation, then channelled that framework into building the 3D Clone Model platform: the conviction, forged over a decade in the operating room, that young surgeons deserve a place to fail safely before they ever touch a patient.

From Saito City, Miyazaki, Horie arrived in Tokyo with a single bag and a dream. In 1970, he founded NICHINAN from scratch, starting with screw-sized precision parts on an engraving machine. Over half a century, the company expanded from consumer electronics prototyping to fabricating concept cars for Nissan, Toyota Auto Body, and Yamaha — vehicles unveiled at the Tokyo Motor Show and the Detroit Auto Show. Today he leads a group of seven-plus subsidiaries, designated a Regional Future Leading Enterprise by Japan’s Ministry of Economy. That entire accumulation of industrial precision now converges on medicine: multi-material monolithic fabrication at 0.02 mm. A Japanese precision atelier powering the next generation of international surgical education — quiet proof that this country still leads.

The Triangle
MEDiDENT drives the business architecture. MIRISE validates clinical truth. NICHINAN manufactures at a precision no other medical-device company can match. This triangle is the reason the platform is trusted — and the reason it cannot be replicated.

Japan's next export is education itself.
日本が次に世界へ渡すのは、教育そのものだ。
Medical education is one of the few infrastructures Japan can export at the highest global standard today.
Cadaver supply is declining worldwide, animal experiments have reached their ethical ceiling, and no enterprise anywhere else integrates precision manufacturing × clinical medicine × medical imaging × XR/AI into a single operational stack.
The 3D Clone Model Platform is the flagship case that simultaneously embodies three national strategies: medical DX, medical-device export, and health diplomacy.
A textbook case of precision manufacturing and automotive-industry know-how redeployed into medicine. Simultaneously raises industrial value-add and medical-device export performance.
