Dr. Williams Discusses Advances in Clinical Orthotics Through 3D Printing Technology
Bruce Williams, DPM, FAAPSM presented critical insights on how 3D Printing Technology is disrupting the manufacturing industry; and custom orthotics are no exception. He explains that the classic method of orthotics manufacturing involves taking a cast, filling with plaster to make the mold, and then removing/subtracting material throughout the process. Additive manufacturing, which is where 3D printing comes in, involves less waste, less use of materials and can control cost in comparison. He shared key differences in 3D printing directly from one’s office versus using a printing provider, pointing out that it is important to understand in-office modifications, production needs, learning curve and the staff usage needed for either option.
After delving into key components of the materials, characteristics and features of 3D printed orthotics, he encouraged attendees to look to the future. In his experience and in literature he presented at the conference, Dr. Williams says that 3D printed orthotics are just as good as traditionally created orthotics, but with the potential to be better due to advanced design capabilities.
We had a chance to ask Dr. Williams a few questions about his lecture, as well:
What do you feel are the top 3 enhancements that 3D printing technology provides in orthotic manufacturing?
Dr. Williams shares that he feels the most stand-out features are:
1. the ability to print in tenths of millimeters for thickness of devices, which can make them lighter and easier to fit in shoes;
2. the ability to print all shell additions into the shell itself with minimal need, if any, for further modifications for most orthotic prescriptive elements; and
3. the opportunity to use segmental thickness changes to maximize functionality and comfort for our patients to improve our orthotic outcomes.
What are the primary challenges that DPMs might face in incorporating this type of technology into their practices?
"The primary challenge is that doctors fear change, despite the fact that access to 3D printing is only going to get easier and easier," he says.
What do you most want attendees at the conference to know about your lecture?
"I want doctors to understand that 3D printing is here and priced competitively," he explains. "There are many options for this, whether it's DIY, or by using a 3D printing company as a lab. I also want doctors to understand that if we truly think foot orthotics are solely the domain of podiatrists, then we should all strive for a deeper understanding of how orthotics work and how they are made so that we can achieve better and more comfortable outcomes for our patients."
Dr. Williams discloses he is a consultant for Arize.
