The Center for 3D Medical Fabrication (3DMedFab) at Georgia Tech has successfully laser sintered resorbable tracheal splints from polycaprolactone (PCL) using an EOS P110 laser sintering system. These splints will be subject to coupled in vitro degradation and fatigue testing as part of an NIH grant, NIH/NICHD (National Institute of Child Health and Development) grant R01 HD 086201. Tracheal splints will also be tested in a large pre-clinical animal model. Both the in vitro and in vivo testing are critical parts of Quality Systems assessment of the airway splint. Experimental results will also be compared to micro-CT and computational simulations.
