Testimonial: 3D printing of model hearts by Phoenix Children’s Hospital workflow made safer with ductless technology

Cardiac surgeons require a great deal of imagery before they operate on a child’s heart.

They need to be able to visualize the arrangement of the heart’s components and defects they want to correct before they embark on surgery.

For decades, visualization imagery was provided by MRIs and CT scans.

Now those imaging technologies are starting points for fully rendered 3D models of the heart, models the surgeons can touch and analyze from all angles before they enter the operating suite.

In a process jointly developed with the Images Processing Applications Lab at Arizona State University, the nationally recognized Cardiac 3D Print Lab at Heart Center at Phoenix Children’s Hospital uses the images produced by MRIs and CT scans to print accurate 3D models of patients’ hearts.

Leading edge activities, however, aren’t always free of workplace hazards.

Production processes in the Cardiac 3D Print Lab entail the use of enamels, epoxies, and adhesives.

Proper safeguards for these processes include adequate ventilation.

“Phoenix Children’s Hospital houses the Cardiac 3D Print Lab which produces 3D printed models for surgical planning, family consultation, and medical education in addition to innovating research.

“Some research applications require epoxies, enamels, plastics, silicones, and dissolving
agents.

“In order to achieve a safe environment without slowing down momentum in research, we purchased the SS-330-DSH. The ductless fume hood was quickly integrated into the laboratory without significant infrastructure change, which would have been very challenging in a hospital.

“The hood allows us to effortlessly move models from the 3D printer to coating or casting processes that need ventilation.

The Cardiac 3D Print Lab uses a Model 400 Floor Sentry with a python hose like the unit shown in this photo to capture 3D printing particles. Like the Model 330 spray hood discussed above, the Model 400 traps respiratory hazards without expensive facility updates. Heavy duty casters and use of standard 115 electrical outlets makes the Model 400 a productive asset in innovative workplaces.

“In addition, we recognized the capabilities of the ductless technology and purchased the SS-400-PYT.

“The Portable Floor Sentry is able to be pushed to the area in the lab that needs it the most.

“It is easy to utilize the Floor Sentry for ventilating our vacuum chambers one moment then to the modified printer with experimental materials.

“Both Sentry units have been integrated into our lab and have been critical to its workflow.”
