Here’s what I know and who I think you can confidently listen to on the topic of 3D printing.
But first, why should you care? What has 3D printing got to do with assistive technology?
To answer these questions I have to first distinguish between two concepts:
- mass production, and
- mass customization.
We’ve all encountered the benefits of mass production. The reason why you can purchase inexpensive products, with confidence that the particular one you take home with you will perform as you expect, is because some company put a tremendous amount of thought into the design of that product and then determined the most cost effective way to produce it.
All of that work was done up-front, before the first component of that product was molded, machined, soldered, welded, or painted. The machines were all purchased – and the workers were all trained on exactly how to do their work with no wasted effort or material. Every widget that comes off the manufacturing line looks and behaves exactly like every other one.
This process really shines when the customer market is large and uniform in its needs and desires – or they’re able to convince that it is. Many years ago, there was a saying that the telephone company would be happy to give you any color telephone you want – as long as you want a black one.
Mass production cannot accommodate late changes or customization because doing so would require creating additional, expensive production lines or returning to square one to redesign, configure, and retrain the factory. That would be even more costly.
The disabled community is neither large nor uniform. Every disabled individual is a unique amalgam of needs and desires. The market for assistive technology doesn’t have a “sweet spot”. Therefore, there’s no place to target your mass production process. This is a community that needs highly customized and personalized products. This is a market that requires mass customization.
There is a new category of technology that is completely general-purpose. Nothing in the shape and function of a 3D printer will give you a hint as to what it can or will create. The 3D printer itself doesn’t know, or care, whether the item that it will create next is in any way like the item it just created. Unlike other machines and manufacturing methods, the 3D-printing process is great at producing something in this run that is “slightly different” from the thing that it just produced. Iterating on a design in an effort to get the best fit, look, and function is a process of enhancement through small changes.
Now combine that inherent characteristic of the 3D-printing process with the fact that the printers themselves are cheap, easy to use, involve inexpensive materials, and are not reliant on other machines or technologies. The result is the ability of non-technologists to create, from scratch, new devices. That work can be done close to the individual who will be the user of the device.
The fact that one can iterate quickly and inexpensively on a device in close proximity to the end user enables the design process to be a cooperative one between the service provider (e.g., therapist, caregiver, teacher) and the service recipient (the individual with disabilities).
Volksswitch tries to make this work easier by supporting the device design and iteration process through the creation of easy-to-use design tools with customization and personalization built-in.
