Inaugural Science Sunday: Slime and Smoothing (12/1)
1. Fun Activity: Make Slime and Oobleck
Our fun activity of the week will be a simple classic. We will make both slime and oobleck and you can take home a container of slime with you as well. Feel free to stop by as long as supplies last even if you aren't planning on participating in our group research project.

2. Group Research Project: 3D Vapor Smoothing Chamber Planning Session
We have selected the design of a new, improved 3D Vapor smoothing chamber as our initial project. This first meeting will be mostly a design and planning meeting covering the following items. (1) The current state of the of the chemical mechanical polishing process will be demonstrated so that improvements can be suggested and tools designed. (2) We will then discuss the proposed design of the 3D vapor smoothing chamber and determine the overall scope and goals of the project (potentially publishable results) as well as putting together a plan to build the first test chamber. (3) We will also work on designing a printed test pattern to use as a sample which will be cross-sectioned (possibly via lapidary type polishing methods after setting in epoxy) and examined under the microscope. (4) We may potentially improve process control using acetone concentration sensors that we develop. This would also potentially allow us to use CFD to model the vapor flow patterns and inform modifications to the design.
See: Vapor Smoothing Chamber for ABS 3D Prints for more details.
Potential Relevant Fields and Skills: 3D printing, Mechanical Design/Engineering, Lapidary/Polishing, Laser (sensor fabrication), Electronics, Automation, Metal Working, Glass Working.
