3d Scanning of a Human Knee & Elbow Joints for Bespoke Medical Device Design

The Challenge:

In order to design a bespoke medical product fitted to an individual's leg or elbow, 3d scans and digital models of the individual's anatomy were needed.

Particular challenges exist for scanning live subjects, namely how to accurately scan an object that is not 100% stationary due to slight human body movements that can occur during the scanning process.

The Solution:

A hand held white light scanner under rapid HD scan mode was used to quickly capture the knee joint geometry. Automatic alignment in the software enabled slight movements in the leg to be accounted for and re-aligned.

The resultant stl scan model was converted to a water tight obj fomat model for subsequent importation into CAD. The models enabled key geometric data to be designed around, a critical requirement of teh project.

Rapid scanning of individual body zones is a cost effective method of capturing key end user geometric data.

Do you have a scanning need?

We are able to scan small and large parts with resolution down to 0.05mm. We have a range of scanning options from hand held light scanners, scanning arm (upon request) and photogrammetry.
