This activity demonstrates the basic challenges and opportunities of nanoscale engineering and manufacturing as an outreach effort to high school science teachers and students using digital projector as a fabrication platform.
A regular video projector provides enough UV light to initiate a photochemical reaction by cleaving a molecule to form free radicals when white light is emitted. The free radicals will polymerize a monomer through an addition polymerization reaction. It will polymerize the solution, becoming solid, only where the white light is projected. It will remain an unreacted liquid elsewhere.
Successive layers are made by lowering the polymerized shape into a beaker of the solution. A thin layer of fresh solution flows over the top and light is again projected to solidify portions of the fresh layer. This is repeated, creating a 3 dimensional object layer by layer.
In the past, the proposed activity has led to development of a 3D printing educational module that engaged students and teachers from more than 10 high schools, showcased at the Illinois State Capitol Educational Fair and the St Louis Science Center. Several student projects from the 2.710 and 2.719 courses at MIT are emerging from this objective, and we expect the students and teachers participating in this proposed IAP activities will develop more projects to accessible educational kits.
