3D technology that supports remote surgery is a brand-new application of 3D. Hopefully virtual reality 3D technology will see more real-world use…
- Save time and improve product quality with 3D technology in bronze casting.
- Airless bicycle tires have been 3D printed, and they will never go flat.

To overcome the distance, Dr. Ye used 3D technology to follow the surgical steps through a virtual reality headset and guide his colleagues with 3D images. A 59-year-old female patient, who asked not to be named, told a local newspaper: “All the bones, muscles and nerves in my body were scanned and processed into 3D images. The fracture site was clearer, so I could understand my own health better.”>> 3D scanners
According to Dr. Ye, 3D technology saved the cost of flying staff in to perform the surgery in person, and it is more sophisticated than using ordinary cameras.>> INDUSTRIAL DESIGN SERVICE

How is 3D technology helping medicine?
Remote surgery guided through virtual reality is just one of many ways 3D technology is changing medicine. What these applications share is turning 2D scans (CT, MRI) into 3D models that doctors can view, measure and work with directly.
- Surgical planning: 3D models of bones, blood vessels and tumors built from CT/MRI images help doctors choose an approach and anticipate risks.
- 3D printed anatomical models: 1:1 physical models help rehearse complex operations, pre-bend plates and screws, and explain procedures to patients.
- Patient-specific guides: bone-cutting guides and dental implant drilling guides designed for each case.
- Virtual and augmented reality: 3D models shown in headsets let remote specialists observe and guide colleagues.
- Training: medical students practice on 3D models and simulations before working on real cases.
From CT scan to 3D model: the basic workflow
The usual workflow has four steps. First, CT or MRI images are exported in DICOM format. Next, specialized software segments the images to isolate the structures of interest, such as bone or blood vessels. The model is then smoothed, repaired and exported to STL. Finally, depending on the purpose, the model goes into a virtual reality environment or is 3D printed in plastic or resin. For highly detailed models such as skulls and teeth, resin is usually preferred; large models such as a pelvis can be printed with FDM to save cost.
Research groups, hospitals and training schools that need anatomical models can check out our 3D printing service for medical and educational models to choose the right material and level of detail.
Challenges in practice
Despite the big potential, 3D in healthcare still needs a stable connection for remote surgery, a technical team that understands both medicine and software, and strict quality control. A 3D model is a decision-support tool; diagnosis and the actual surgery remain the doctor’s job.
Frequently asked questions
How does remote surgery with virtual reality work?
The lead surgeon, located elsewhere, watches the operation through 3D images and live video and guides the on-site team with images and instructions shown on their virtual or augmented reality devices. The surgery itself is still performed by the doctors at the hospital.
Where do anatomical 3D models come from?
They are built from the patient’s own CT or MRI scans, using segmentation software to isolate the structures to be viewed. The data can then be shown on a computer or VR device, or 3D printed as a physical model.
What materials are used to 3D print medical models?
PLA and ABS are common for large models, and resin for models that need fine detail. For models that simulate soft tissue, you can use elastic materials or cast silicone in a 3D printed mold.
Can small hospitals use 3D technology?
Yes. Many applications, such as printed anatomical models or surgical guides, don’t require buying machines and can be outsourced case by case. What matters is a standard imaging workflow and close cooperation between doctors and the technical partner.
