We had our first meeting with the Clinicians at UMD school of medicine this past week and have a solid set of task and goals for the coming months of our project.
To educate the department on 3D printing, we will be attending three physical therapy classes throughout the month of January to present a short curriculum on 3D printing technology. In the first class we will be lecturing to over 60 physical therapy students about the uses of 3D printing technology in medicine. In a second class, the professors will provide case studies for the students to evaluate in order to discuss produce potential 3D printed solutions. Each group of students will make a model out of playdough and other materials to create their prototype. Those objects will be brought back to our lab for 3D printing. In our third class we will be presenting the students with their 3D printed models. We hope this entire curriculum will motivate the students to utilize 3D printing in their medical practices.
As a side project we are also printing spare parts for the occupational therapist to use immediately in their current practice. The clinicians have requested a set of crutch tips to replace the missing and broken ones on their current set of crutches for their patients. This will empower clinicians to continue replacing parts with 3D printed replacements whenever they need them.
In terms of printing we have a lot to accomplish:
- 20 basic crutch tips (some plastic some ninja flex to test both materials)
- Model of potential grip a clinician designed during our meeting
- More test models
We also have to
- Submit our TAPIA poster
- Create a small presentation/curriculum to educate the physical therapy students.
We got some good news from CREU about our deadline for the TAPIA posters being extended till January. This alleviates some pressure from meeting the initial deadline.
I just got back from the Igniting Innovation Summit on Social Entrepreneurship conference at Harvard University. This evening, I stopped by the lab and printed a test crutch tip on the Afinia. The structure came out well, however, there is some build up on the bottom of the tip.
Here are the pictures of the test:
I am striving to print at least 5 crutch tips and before Thanksgiving.
Today, Sam and I met with the physical therapists, Karen Gordes and Dr. McCombe Waller. It was a very productive weekend.
They explained that they would like us
- to interface with the students.
- to teach students how could you use 3D printing and how to customize grips for crutches.
- teach students different ways they could think of using 3D printing.
- would like to see a team evolve where we are working with the students to help them develop designs.
They mentioned there is a 3D printer in the University of Maryland Library for our use. We suggested that we could bring some people from our lab and printers for the students to use for the duration of our visits.
Their goal is for the students to understand collaborations. We are scheduled to hold several sessions with the physical therapy students (65 students).
First, we are holding a lecture called “Interprofessional Technology Development” which will be an introduction to 3D printing and how it relates and is incorporated with medicine (focusing specifically on assistive devices). Also, we will bring some examples of 3D printed objects(handle modifications) made with different materials for the student’s viewing.
Then, we will have a follow-up session where we will help them develop the designs for their assigned cases to ensure the designs are ready to print by the end of the second session.
The third session is solely for printing the designs the physical therapy students created during the second session.
We have tentative dates for the sessions.
- An introductory lecture on what 3D modeling is and how it can be utilized by physical therapists.
- Scheduled for 1/22 from 2:00 – 4:00pm (Allied Health Building, Room 219)
- Snow back-up date: 1/29 from 2:00 -4:00pm
- A lab that incorporates 6 patient cases where 3D technology can be used to modify assistive devices. Students will be introduced to design ideas, how to design and information on 3D printing of their design ideas.
- Scheduling options: 3/23 from 2:00 – 5:00pm (Allied Health Building, Room 146/152), or 3/31 from 2:00-5:00pm(Allied Health Building, Room 146/152)
- A lab where the completed 3D items are brought back for student review and discussion.
- Scheduling options: 4/4 from 3:00 – 5:00pm, or 4/5 from11:00 – 1:00 (Allied Health Building, Room 146/152) [4/5 is preferred date, can alter time on this date]
We received feedback from some of our prototype grips. They liked two of our grips. There was a request for a 3D print of the clear cylindrical grip that is slightly wider from the original using the ninjaflex filament.
In addition, they would like 20 crutch tips, rocker bottom and a grip with a flair at one end. Dr. McCombe Waller designed the grip w/ a flair end with play-doh. We plan on using memento to create a 3D model.
For this week, our main focus is completing the conference for TAPIA and then we will begin 3D printing our requests.
Forearm prototype model
While researching grips, I found an article about a Georgia Tech graduate Partha Unnava which has 3D printed a new design for crutches. It incorporates the same ideas we had for forearm support bar and better grip. However, these crutches require completely new manufacturing. We would like to see if we can incorporate his grip design concepts but attach it to pre-existing crutches many people and business already own. By physically lowering an average crutch to it’s shortest setting, we can potentially replicate this type of design while saving people money and resources. Designs of the crutch are currently in progress.
We have also successfully set one of our printers to print Ninja Flex! Meaning we can build softer and more pliable grips with our 3D printer
This week, we are working on the poster for TAPIA 2016. We are designating our weekly lab meeting to working together on the poster.
