The printing diameter is an important measure in InFoam Printing. Unfortunately, it changes with every foam type. Measuring by hand is time consuming and not very accurate. The challenge was to automate and standardise this measuring process.

Low-cost and easy to handle
My approach was to establish a repeatable process that could be handled in our lab. Therefore, I developed the following workflow:
Making Samples| I injected sticks into foam blocks. This foam I cut into uniform slices to get cross-cuts.
Photographing| I took pictures of all foam slices inside a white-box. The box guaranteed an even lighting and no variations between samples.
Measuring| The series of pictures was fed into ImageJ - a free program for scientific image analysis. I wrote a program that would automatically find the four samples in each foam slice and measure the diameter.
Analysing| All measured diameters were sent to MS Excel where I condensed the data into one average diameter.

What's the advantage?
By adjusting the diameter, we controlled when sticks would fuse together. We used this in all kinds of designs.
Our samples got more precise, which was especially important in cooperation projects.
We saved material and time because we could print the exact diameter we wanted.
We were able to adjust the flexibility of structures by changing the diameter.
