Applications

  • Advanced surgical rehearsal and preoperative planning
  • Organ behavior prediction

Technology Overview

Current 3D printed organ models are built using hard plastic and lack mimicry of the physical properties of real tissue. Important differences between tactile sensation and mechanical properties between hard plastic and tissue limit their application in preoperative planning and surgical rehearsal. Researchers at the University of Minnesota have developed a method to 3D print patient-specific organ models using soft silicone with realistic tissue-mimicking properties. These 3D printed models can also be equipped with integrated 3D printed sensors that collect quantitative feedback.

Phase of Development

TRL: 4-5
Working prototype. Prostate and aortic models have been successfully printed.
