The tripod base has been added to the flexible insole for Lynne's foot. We are still prototyping the corner arch support. The second insole design is in progress and we are experimenting with different flexible materials.
April 8-22 2016
After the meeting we set some new goals we wanted to achieve by the stem symposium. We are working on putting a flat, tripod like base on the insoles to stabilize them. In addition, we are creating a small, stabilizing corner to hold up the arch on the basic insole and still have it be able to fit into a shoe. Finally, we are working on replicating the process for Lynne's insole on a separate foot scan.

We had our second meeting with Prof. Santiago Muños. He looked over our design, and suggested that we research and design a heel wedge rather than a heel cup. He also showed us how to sand down our insoles to create a more finished look.
April 1 2016
We attended the Pittsburgh Regional Science and Engineering Fair! It was a great experience and we learned a lot!
Spring Break
Continued designing the heel cup, prepared for the Pittsburgh Regional Science and Engineering Fair.
Feb. 28 2016 through Mar. 12 2016
We researched a design for the hell cup, looking for a shape that wold mold to the insole and fit in the shoe. We discussed the viability of the different plastics and ruled out NinjaFlex as the plastic for the stand alone insole.
Jan. 26 2016 through Feb. 21 2016
During these classes we have been working on created a supported insole that can be printed. We are experimenting with different plastics and designs.
Jan. 26 2016
Using the original foot scan, we're applying the advice we got from our city as our campus meeting using MeshMixer and TinkerCad.
Jan. 21 2016
We had our first city as our campus meeting! We received a lot of feedback and materials to help us develop our insoles. See the "City As Our Campus" page.
Jan. 14 2016
Using a soldering iron we cut the orthotics out of the plastic forms. They still have rough edges which we will work on shaping and sanding.
Jan. 12 2016
Today we went back to tech shop in our two hour period. We vacuum formed on the ABS foot print with the 1/8th in PETG plastic. Since the pack we ordered had 5 sheets, we were able to make three forms (2 of which were successful).
Jan. 6 2016
Writing our Research Plan for the PRSEF. For this we adapted and used some parts of our original proposal to outline out work clearly.
Jan. 4 2016
Today we wrote our abstract for submission to the PRSEF. We also continued to work on designs to print and vacuum form for once the plastics come in.
Winter Break
Plastics to form in have been ordered. We bought PETG plastics in 1/8th and 1/16th inch thicknesses. This is a pretty rigid plastic, so we might need to experiment with more flexible ones. We also got two different sizes to see if we can use the smaller plastic on the former (less waste).
Dec. 7 through Dec. 11 2015
We continued to work on designs so that we can make use of the Vacuum former during winter break. We are doing research on plastics we can use to print in and ones we can form in so that we can order them in time. We need a plastic with a higher melting point so that it doesn't get melted in the vacuum former. We are working on way to accurately print the ABS foot so that it doesn't shrink and come off the plate.
Dec. 3 2015
Today we went to Tech Shop to learn and get certified on the vacuum former.
Dec. 1 2015
After working on the model for the second prototype outside of class, we printed the new design. (3)
Today we are beginning design on the third prototype. This one will take less time since we do not need to start over completely, we just need to modify our second prototype design. We are also starting research on different materials that we can print with. On the 3rd we are going to Tech Shop to learn how to use the vacuum former. This will open up the option of using different types of materials that we can then test.
Nov. 23 2015
We have completed our first prototype! It printed well, but the insole didn't reach all the way across the foot (2e). Now, we are working on extending the arch support by modeling off of the full foot scan rather than the cropped foot scan.
Nov. 13 2015
Today we continued to update our research blog to accurately represent where we are in our progress. We also continued to edit the initial prototype model that we created on MeshMixer. We are researching the kind of person that we would like to meet with for our city as our campus connection, as well as continuing to research foot orthotics.
Nov. 11 2015
We've been familiarizing ourselves with MeshMixer. After some trial and error, we've figured out how to create an insole from the positive mold. Next step, smoothing some edges and printing!
Nov. 9 2015
We have completed the parts of our first low-res prototype (pictures can be found under the Images and Visuals tab). The MeshMixer 3D model will represent the parts of our prototype as a whole.
Nov. 5 2015
Today we started our blog! As we continue to update it, we have also imported the positive mold of our scanned foot into MeshMixer. We are experimenting with different ways to modify the mold to create a corrective insole.
