Enhanced in-line mixing of 3d-printed pastes
Geoff Brennecka | gbrennec@mines.edu
3d printing of ceramics with graded properties (e.g., permittivity, porosity, elastic modulus, etc.) using a multi-feedstock printer is promising for a number of applications, but is currently limited by how well the different feedstock pastes mix during extrusion. We want to take advantage of the shear-thinning nature of these pastes in order to improve mixing with minimal dead space by adding controlled agitation to the mixing/print head.

Mentoring Plan
my office is across the hall from the lab and my door is always open (in other words, I won’t be looking over the student’s shoulder, but I’m very accessible); the student will be invited to (and hopefully actively participate in) biweekly research group meetings; multiple graduate students will also be in the lab and occasionally working with the printer(s)
