PURPOSE
Neuroanatomy learning continues outside of the cadaveric laboratory or the
virtual reality suite. Seeking a cost-effective approach, we turned our
attention to 3-D printed anatomical models. This approach offered a more
cost-efficient approach through the availability of 3D printers. We we
discuss the proof-of-concept approach to introducing 3-D neuroanatomy models
to the classroom. Through our observational data, we determined that the
models have use in the classroom and require learning activities designed
around the models to keep student interest high.
METHODS
We used two BambuLab X1 3D-printers (BambuLab, Austin, TX) to print models
using polylactic acid (PLA) filament. Models were sliced using Bambu Studio
(BambuLab, Austin, TX). Identified models met the following criteria:
anatomical accuracy, general aesthetics, license for educational use, and
cost. Many of the models we reviewed failed to have the accuracy and
sufficient resolution to be used as in-class models. We identified two models
that met the outlined criteria.
RESULTS
Whole brain and brainstem models were placed on 10 tables (seating 6
students each) during the course. Several students used the models during the
sessions, while most focused their attention on the presentation. We had
hoped to have more student engagement with the models. Upon reflection, model
integration with each session, through hands-on activities, could result in
widespread use. We've identified several approaches to integrate the models
and expand their use in the classroom.
CONCLUSION
By introducing the use of 3-D printed models in the classroom, we hope to
increase classroom engagement, learning and knowledge retention. We estimate
that the total cost for licensing, printing material each of brains and
brainstems was less than $500. Given this information, we would like to
introduce more models and integrate them with in-class session activities of
the neuroscience course.
