Researchers print lifelike 3-D organ models for surgeons to practise on

Using a 3-D printer, researchers at the University of Minnesota created lifelike artificial organ models that mimic the exact anatomical structure, mechanical properties and look and feel of real organs.

These patient-specific organ models, which include integrated soft sensors, can be used to practise surgery on – to improve post-operative outcomes.

“The organ models we are 3-D printing are almost a perfect replica in terms of the look and feel of an individual’s organ, using our custom-built 3-D printers,” said lead researcher Michael McAlpine of the University of Minnesota’s College of Science and Engineering.

Researchers hope to use this new method to 3-D print lifelike models of more complicated organs, using multiple inks so surgeons could see a tumour or deformity and test various strategies for removing them or correcting complications.
