What it is
What is a 3D-printed cast?
A 3D-printed cast is an alternative to a traditional cast, made to the exact shape of the patient's limb. Instead of wrapping plaster or fiberglass around the arm, the clinic team scans the limb with an iPad, software designs a cast that fits the scan, and the cast is printed on an industrial printer.
The cast is printed as an open lattice: it gives support where it's needed and leaves the rest of the skin exposed to air and water. That makes it lightweight, ventilated and easy to clean. Every patient picks the color and pattern.
The process
How do you get a 3D-printed cast?
- 01
Scan
The limb is scanned with the Gero app on an iPad in under two minutes. At the first visit, the patient gets a temporary splint (ONE Splint).
- 02
Customize
The doctor chooses the cast type, and the patient picks a color and pattern. The app shows a preview.
- 03
Print
The software designs the cast automatically, and it's printed by certified manufacturing partners.
- 04
Fit
The cast arrives at the clinic within 3 days and replaces the temporary splint.
From scan to model
One visit, one iPad, one order
The team scans, checks the 3D model on screen and taps "Done." From there the software takes over: the cast is designed, checked and sent to print.
Production
From the printer to the patient
Every cast is printed layer by layer from a file the software created for one patient. Drag the handle to see a cast fresh out of the printer, and the finished product.
Comparison
3D-printed cast vs. traditional cast
| Gero 3D-printed cast | Traditional cast | |
|---|---|---|
| Weight | About 60 g | 1.5 to 2 kg |
| Fit | Designed from a 3D scan of the patient's limb | Wrapped and molded by hand on the limb |
| Water | Water-resistant: showering and swimming, with the doctor's approval | Usually has to be kept dry |
| Ventilation | Open structure that lets air flow and allows cleaning | Closed, so the skin underneath gets no air |
| Removal | No electric saw | Usually with a cast saw |
| Design | Color and pattern chosen by the patient | Usually white or a single color |
| At the clinic | Scan and order from one app, no cast room | Cast room, water basins and materials |

FAQs
Questions about 3D-printed casts
What is a 3D-printed cast?
A cast made by 3D printing from a scan of the patient's limb. Instead of wrapping plaster or fiberglass, the limb is scanned, software designs a cast that fits its shape, and the cast is printed as an open, ventilated structure.
Can I shower and swim with the cast?
The Gero cast is water-resistant, so you can shower and swim with it. Get approval from your treating doctor before swimming or sports. After it gets wet, dry the cast with a fan on a low-temperature setting.
Which injuries is a 3D-printed cast suitable for?
Gero casts are currently designed for fractures and conditions of the wrist, forearm, hand and thumb, including scaphoid fractures and De Quervain's tenosynovitis. The orthopedic doctor decides whether a 3D-printed cast is right for each patient's specific condition.
How long does it take to get the cast?
The cast is printed and shipped to the clinic within 3 days of the order. At the first visit, the patient gets a temporary splint (ONE Splint) for the first few days, until the custom cast arrives.
How is the cast removed?
The cast opens and comes off without a cast saw.
How much does a 3D-printed cast weigh?
A Gero cast weighs about 60 g. A traditional plaster cast usually weighs 1.5 to 2 kg.
What is the cast made of?
Biocompatible materials chosen to be skin-friendly, lightweight and durable.
