3D PRINTING CONFERENCE INNOVATION,
MODELLING, APPLICATION & IMPLEMENTATION
This research focused on the characterization of additive
manufacturing technology based on composite filament
fabrication (CFF) as a design input for a novel foot-ankle
device. CFF utilizes a similar method of layer by layer
printing as fused filament fabrication, but is also capable of
reinforcing parts with layers of various continuous fibers into
a polymer matrix. Due to the orthotropic characteristics of
additive manufacturing based on fused filament fabrication,
3D printed parts may present different mechanical behaviour
under different orientations of stress. Furthermore,
technologies such as CFF allow a range of configurations to
fabricate and reinforce the parts. In this study, mechanical
characterization of polyamide 6 (PA6) reinforced with
carbon fiber and fiberglass was conducted by design of
experiment as a statistical method, to investigate the effect
of reinforcement, print orientation and percentage of fiber
on mechanical properties in compression and flexion. The
results were considered as an input to design and validate a
novel low-cost foot-ankle device by using CAD and CAE tools.
Speaker Biography
Miguel Araya-Calvo is currently working on a Master’s degree thesis in Medical
Device Engineering from the Instituto Tecnológico de Costa Rica, Costa Rica, related
with a novel foot-ankle design implementing fiber-reinforced additive manufacturing
technology. He is a researcher at the ergonomics and biomechanics laboratory and an
Industrial Design Engineering professor at Instituto Tecnológico de Costa Rica. He has
focused for more than 3 years on the implementation of 3D printing for low cost below-
the-knee prosthetic solutions.
