3D PRINTING AND VETERINARY MEDICINE.

In PennDesign’s Fabrication Lab, students and faculty use three-dimensional printers to craft geometric forms, architectural models, and other products of the imagination. But in a recent collaboration with the School of Veterinary Medicine, the printers have been put to work making models based very much on reality. After examining a skull deformity afflicting a canine patient named Millie, Evelyn Galban, a neurosurgeon and lecturer in Penn Vet’s Department of Clinical Studies-Philadelphia, thought it would be useful to physically handle a replica of the dog’s skull. “It’s difficult to fully understand the malformation until we have it in our hands,” she says. “That usually doesn’t happen until we’re in surgery.” The expertise of PennDesign’s Stephen Smeltzer and Dennis Pierattini partnered with Galban, along with veterinary neurology residents Jon Wood and Leontine Benedicenti, to produce models that precisely replicate injuries or deformities of pet dogs and cats. These applications have the potential to improve training and patient care at Penn Vet, while stretching the imaginations of PennDesign students and faculty. Pierattini remarked they are very interested in finding more ways that can explore the potential of the equipment and fathom its depths. The veterinarians took CAT scan, then transformed CAT scan files into a format that the 3D printers could recognize.They produced the skull of Millie, composed of gypsum powder bound by acrylic and sealed with a super glue-like substance to make it rigid. These models could help vets like Evelyn Galban plot out and practice surgical procedures in advance of an operation. Full-color models may even allow for testing new approaches that avoid contact with critical blood vessels and other tissues. Read more;
