CBMTI now 3D prints detailed multi-material models that mimic real anatomy, even down to a specific patient’s tumor. With access to advanced multi-material 3D printing, CBMTI can fabricate models that feature different textures and densities over surfaces and throughout interiors, just as human body parts do.“The [Stratasys] J750 allows us to create models with both texture and color variations that mimic actual tissue handling and appearance better for these complex models,” said Dr. Waran. “With the Connex, we can simulate realistic layers of human tissue like skin, bone, dura, brain, and tumors within the printed model for surgical simulations.”
CBMTI develops its training courses in partnership with leaders in various fields. Together, they identify a patient with the anatomy and pathology they wish to train physicians to treat. CBMTI engineers then convert the patient’s CT and MRI scans into digital design files and select materials that best match the physical, tactile and color characteristics of the target anatomy. CBMTI has even found ways to use support material, typically removed from the final model, to enhance clinical realism.“We have also incorporated features such as fluid dynamics so we can simulate endoscopic neurosurgical procedures,” said Yuwaraj Kumar Balakrishnan, CBMTI chief operations officer.
“We find surgeons who train on these models are much better prepared in terms of dealing with complex surgeries, simply because they are able to train and retrain on the models until they perfect the procedure.”
