Version 3.9

Vortrag: Designing a 3D printed tool for medical use

From reverse engineering to iterative design


As part of a project to make medicine more accessible in disadvantaged communities, I am making usable 3D-printed copies of surgical tools. This talk will go through the process of turning an existing commercially available hemostat into a 3D-printable model. I will show how I started with a native 1:1 copy of the tool and went through several iterations to match the functional properties of the original. I'll show the problems with each iteration and how I went about solving them. In the end, I'll talk a bit about how these tools are going to be used and the impact they will have.

Making a working real-world copy of a working real-world object is not as easy as copy and paste (or scan and print). It turns out materials matter. I'll show you how each iteration of the design failed the usability test, what was done to correct it, and how the changes were implemented and tested. I've brought along printed copies of several in-between steps so you can see and feel the difference. I'll also show you the custom CAD library that was developed to make this design possible using 100% open source tools. The purpose of this work is to allow medical equipment to be manufactured locally in low-resource areas using small-scale technologies. I'll tell you a few words about the scope of this project and what we've done so far.
