Abstract:

This paper presents the development of several 3D printed anatomical models that are being used for training nursing students at the College of Nursing at the University of Alabama in Huntsville (UAH). These models were developed through a collaborative effort between the two entities.

The following 3D training models have been developed:
1) human heart,
2) human brain,
3) placenta and
4) compression fracture at L1.

The 3D printed human heart model is being used to assist nursing students visualize the intricacies of the heart. The students are able to hold and manipulate the model and get an up close look resulting in a better understanding of the heart’s shape and structure. The 3D printed brain is being used to assist students better understand and to more easily visualize lesions in multiple sclerosis (MS) patients. The models help patients understand the reason for their diagnosis and the progression of MS as the lesions grow and develop. The placenta training model was scanned from a model, a STL file created and a 3D part made using PLA filament. The nursing faculty commented that the 3D printed placenta lacked flexibility. Another 3D part was made with a TPU filament. Again the nursing faculty stated that the model was not realistic. A rubber mold was then made from the 3D part and a silicon part was made. Color pigment was added in the mold to give the placenta a realistic look. The finished part was then heated several times to add some flexibility. Two MRIs were acquired from the same patient, one showing a compression fracture for L1 and the second MRI showing the L1 after the kyphoplasty procedure. 3D printed models are being made to show these two conditions. The College of Nursing has developed over one hundred simulation training scenarios. The 3D printed models have been added into these simulation training scenarios and are being used to provide nursing students with much needed hands-on experience, allowing the students to practice specific skills in a safe environment. Included in this paper are a description of the College of Nursing, the 3D printer lab, the 3D printed models, the use of the models in nurse training and the results and benefits.
