What is 3D printing?

3D printing is an additive process by which material is printed layer by layer using a computer aided design (CAD) program.
Traditional printing of models utilizes a subtractive process where material is cut away to create the design. (think clay modeling)
3D printing is ideal for hollow models and can be personalized for each individual patient's anatomy using CT and MRI scans to provide the data for the CAD programs.

Implications Nursing Informatics
3D printing can be applied to nursing in patient care, patient education and nursing education. The models are currently used in physician residency training programs to aid in surgical practice. With continuing research in bioprinting, the models have more life like feel and consistency of real tissue. These models can be used in the same way with nursing education.

Case Study

Hseih, Dedhia, Cervenka and Tollefson (2017) reported a small study in which 3D models were used to create mandibular reconstruction plates. "The group treated with 3D printed prebent plates demonstrated significantly better postoperative facial contour symmetry (p<0.05) than the group treated with intraoperative bent plates" (Hesiah, Dedhia, Cervenka, & Tollefson, 2017, p. 293)

Pros

Why is 3D printing beneficial?

Patient specific models
- better fit, less pain, less complications
surgical practice on patient specific anatomy
nursing and medical education with anatomically correct models; can possibly replace cadavers

Cons

danielle_daquisto — 2017-10-08 20:43:35 UTC

What are the challenges to using 3D printing?

consistent print technique and duplicative models. Currently, printing is not regulated, so the quality of the models depends on the manufacturer.
Length of time to produce a product. Current techniques require long lead time to produce a patient specific product. This cannot be used urgently.
Lack of FDA approval for many products.
Ethical considerations. There is some thought that this technology can be used to create super humans, especially when utilizing biological printing substances.

Opinion

danielle_daquisto — 2017-10-09 01:46:20 UTC

3D technology has exciting applications in healthcare. Research on biofabrication “the marriage of 3D printing with tissue engineering” (Paxton, Powell, & Woodruff, 2016, p. 190) can change nursing care. Think about a world with skin grafts that could potentially have an antimicrobial component. Decreased wound infections would result. Implants that are patient specific would result in less pain, more function and decreased length of stay due to quicker recovery time. The ability to create patient specific models for less cost would mean more anatomic models for all students and would enhance learning. More access to simulation not only in schools but in the hospital for inpatient nurses would keep the staff up to date and more engaged in continuous learning.
