Can I use Structure Sensor (Mark II) for prosthetics and orthotics?

One of the best uses for our sensor is for custom orthotics and prosthetics.

In another lifetime, doctors needed to use foam or plaster to create molds of their patients' limbs. This was expensive and time-consuming, and there was always the chance that the mold would become damaged during delivery.

Now, with the convenience of commercial 3D sensors and specific app support, what could take hundreds of dollars and several days can be done much more inexpensively, and close to instantaneously.

What equipment do I need?

  • Structure Sensor (Mark II)
  • Lightning cable (or USB-C cable, depending on your iPad model)
  • Compatible iPad
  • matching bracket

While we do not sell iPads, the remaining equipment can be purchased through our web store.

TechMed3D also sells some orthotic/prosthetic-specific hardware here.


What software do I need?

The software you use depends on how technically-savvy you consider yourself.

You can find more general 3D-scanning apps here. These will require you to further prepare the file and find a manufacturer.

If you want more orthotic/prosthetic-specific apps, please check out these medical apps.


Will your sensor be accurate enough?

Thousands of physicians across the world have used our sensors to replace their traditional foam and plaster molds. 

The precision of Structure Sensor (Mark II) can be found on this chart.
We are still collecting data and running case studies but, from what we have seen working with professionals in the field is that, most measurements are within 1-2% when verified against a manual tape measure or existing blueprints.
