Meet the Maker – Lu Jiang

This week’s maker is Lu Jiang, graduate student in the Department of Bioengineering at UCSF. Let’s take a look at her project.

Q: What did you make?

I made an acrylic sheet as an integral part of a sparse scatter sampling grid to hold alloy segments.

Q: Why did you want to make it?

It is being used for a research project in my lab. We are designing a novel sparse scatter sampling grid to study scattering in cone-beam Computed Tomography.

Q: What was your process?

I used the laser cutter at the Makers Lab to help cut holes in the acrylic sheet.

Four sheets of acrylic with different grid dimensions placed side by side for comparison.
Different grid sizes were laser cut out of acrylic plastic to find the optimal dimensions for alloy segments

Q: What was the hardest part of the process?

The laser cutter is precise, but I needed to find the optimal hole dimensions for the alloy segments, which would not be too loose or too tight. Therefore, I cut many sheets to test which one could fit these segments best.

Q: What was your favorite part of the process?

Drawing a sketch and watching the laser cutter complete the job was the most interesting part.

Q: How did this help make you a better graduate student?

I learned how to use Autodesk Fusion 360, a powerful tool that can be useful in the future when I want to experiment with 3D printing.

Q: What do you want to make next?

I want to experiment with 3D printing other grid designs for various alloy segment arrangements and conduct X-ray experiments.
