Abstract
Stimuli responsive materials have shown great potential in the ability to add functionality
to designs to achieve and complete certain tasks. While not ubiquitous, applications so far have
been found in fields of soft robotics in the case of mechanical grippers to drug delivery
for minimally invasive surgeries. These materials operate by exhibiting certain mechanical
properties once under the stimulation from an external stimulus. In the case of Magnetic Shape
Memory Polymer (M-SMP), it responds with a combination of magnetic field intensity and
direction along with temperature control to allow shape locking and unlocking below and above
the glass transition temperature, respectively. Current fabrication methods inhibit the ability
to combine functional ability of configurable mechanical properties with functional designs such
as those used in springs. In this thesis, a method of 3D printing, Digital Light Processing (DLP),
is explored as an avenue to develop and characterize feasibility and quality of printing custom
complex millimeter-scale components. In developing a custom DLP enabled setup, formulating
photosensitive m-SMP resin, and demonstrating functionality combined with various
complexity, it is shown that it is possible to combine design complexity with material
functionality. This research effectively expands the ability to apply complex geometric designs
that can be manufactured and allows a fuller range of ability of fabricated parts.
